Gast Group – the leading designer and manufacturer of precision air products and member of IDEX Corporation’s Health & Science Technologies division – will be using its stand (A1.550) at drinktec 2017 to promote its products and services for beverage dispense applications.
Traditionally CO2 has been used to operate beer and soft drinks syrup pumps but, due to environmental and health & safety concerns, many venues are introducing compressors for larger installations, which has led to a significant increase in demand for compressed air to replace CO2 in beverage dispensing systems.
Besides reducing the number of gas cylinders that need to be stored and handled, an on-site compressed air generator can be used to dispense draught beer (from traditional kegs to 500-1000 litre pressurised beer tanks); pump beer, wine and syrup; and operate bag-in-box and blend-in-cup installations for the dispensing of other drinks.
Gast Group will be using drinktec 2017 to showcase its JUN-AIR 86/87R Series Systems, which are designed to suit virtually any beverage or liquid food application and be even quieter and more durable in operation. They provide best-in-class reliability, quality and performance; and their compact footprint makes them easy to install and ready to use at point-of-installation, making them easily integrated into most applications.
Also on the stand – and ideal for beverage and liquid food applications – are Gast Group’s new LubeFree options, which utilise a proprietary vane material to provide versatility and allow users the options to oil or not oil the motor.
Gast Group in Action
Heineken’s Orion and Cellar-beer dispense systems consist of a series of 250, 500 or 1000 litre stainless steel tanks, installed in either a cold room or water-cooled insulated beer-tank and filled from beer trucks or road tankers.
Unlike traditional kegs that rely on CO2 for dispense, the Heineken systems use compressed air from JUN-AIR compressors or GAST rocking pistons to pressurise the tanks and squeeze the beer-filled in-liners to deliver beer to the taps. This method also improves health and safety in the workplace as employees don’t handle heavy barrels or gas canisters.
For Heineken’s Cellar-beer, a wall-mounted JUN-AIR OF312 compressor with an 8.5 litre receiver tank produces compressed air at 2.5 bar to deliver the beer at 25 l/min, sufficient for up to five taps. The Orion system uses a wall-mounted Gast 82R rocking piston fitted with an 8.5 litre stainless steel receiver tank and is capable of delivering beer at 20 l/min, sufficient for four taps. For larger venues, Heineken also specifies JUN-AIR’s OF1202 fitted with two 8.5 litre receiver tanks, which are connected in series and capable of dispensing beer to as many as 90 taps.
Summarising, a Heineken spokesperson says: “We have used electric pumps to deliver beer but, since developing the Cellar-beer 2000 system, the JUN-AIR and GAST compressors have helped us set new standards. They are a reliable source and I am confident in talking to the company about future innovations, specifications and developments to our dispense systems.”
Gast Group’s expertise covers multiple applications and is supported by an extensive knowledge of compressed air applications in the food and beverage sector; with customers benefitting from the company’s many successful relationships with OEMs and partnerships with equipment distributors.
Gast Group will also be promoting other GAST and JUN-AIR oil-less and oil-lubricated ranges of clean and quiet compressed air solutions at Drinktec 2017. For further information call Gast Group on +44 (0)1527 504040, email gastgroup.uk@idexcorp.com or visit www.gastmfg.com.
GAST – the leading designer and manufacturer of precision air products and member of IDEX Corporation’s Health & Science division – is introducing a new range of vacuum pumps and compressors to its extensive portfolio. These new products are simple in operation, robust and an effective source of compressed air. The three pump and compressor ranges include sixteen oil-free and oil-lubricated rotary vane models and, in a first for the organization, four claw pump models.
Announcing the new ranges, Gast Group's Andrew Lidington explains that the company has extensive knowledge of the pneumatic industry and its customers’ needs continually drive the development and introduction of new and innovative products.
“GAST is already renowned as a world-class manufacturer of vacuum pumps and compressors and these additions to our portfolio will provide customers with products that, compared to our traditional offering, can deliver even greater flow and deeper vacuum. The addition of claw pumps also perfectly complements our portfolio and opens up new industries and sectors that we haven’t been able to participate in previously.” says Andrew.
“Using simulation software and the latest manufacturing techniques, we believe that the performance of our new rotary vane and claw pump models are class-leading. The range is also more environmentally-friendly than ever and, thanks to extended maintenance schedules, total cost of ownership is also significantly improved.” he says.
GAST Claw Pumps
Claw pumps are an often-overlooked technology due to a slightly higher initial cost. However, compared to oil-free rotary vane, claw pumps use significantly less horsepower to provide similar vacuum capability. They also provide 100% duty cycle and, with no carbon vanes and significantly less gear lubricant to replace, are quicker, easier and cheaper to maintain.
With only moderate energy consumption and very high efficiency, GAST’s four new claw pump models – PA.155, PA.315, VA.155 and VA.315 – use contactless rotors that are synchronized by gears without any lubrication in the pumping chamber. This frictionless operation avoids any residue (generated by rubbing during rotation) from contaminating the air supply; and means lower maintenance and operating costs, longer lasting performance and improved total cost of ownership.
With nominal capacities from 186 to 360m3/h at 60Hz, vacuum capability to 25.5”HgV and pressures up to 17psi, the GAST claw pump range is ideal for numerous vacuum, compression, aeration, extraction and drying applications in sectors including printing, environmental, medical, bulk material handling, CNC machining and vacuum hold-down.
GAST Oil-Free Rotary Vane Pumps
Adding to an already impressive portfolio of rotary vane pumps, two new oil-free models – SB.16 and SB.40 – being introduced feature an industrial Monobloc design with the rotor assembled directly on the motor shaft. This direct-drive design means fewer moving parts, making these new dry vacuum pumps extremely compact, reliable and easy to maintain. Additionally, a rear centrifugal fan ensures optimal cooling of the pump and each model is equipped with protective filters at the inlet and silencers at the outlet. Both models are also suitable for use as compressors.
A third model, the SC.100, has the rotor installed on the shaft and fixed by two bearings, with the motor being connected by a flexible coupling. The fan is installed between the pump housing and motor to ensure optimal cooling; and a robust and compact housing provides protection and keeps noise levels extremely low.
GAST’s new oil-free rotary vane models offer nominal capacities from 19 to 150m3/h at 60Hz. All models provide vacuum in excess of 26”HgV and are ideal for applications including printing, conveying, wood/plastic presses, automated packaging and pick and place operations.
GAST Oil-Lubricated Rotary Vane Pumps
Ideal for applications as diverse as laboratory conditioning/refrigeration appliances, mass spectrometry, packaging, medical equipment, thermoforming machines and glass and marble machining, GAST’s new ten-model range of oil-lubricated rotary vane pumps – including the LB.8, LC.12, LC20, LC.25, LC40, LC60, LC106, LC151, LC.205 and LC.305 – are ideal where the intake flow may require higher flow and deeper vacuum.
Additionally, and for applications where intake vapour is considerable, a WR version also features an integral system that separates oil and water condensate, which is then expelled when the pump is stopped.
All six oil-lubricated models offer nominal capacities from 9 to 365m3/h at 60Hz and total final pressures between 1.5 and 0.08 Torr.
Summarising, Andrew Lidington says that, thanks to their advanced performance, durability and ease of maintenance and serviceability, GAST products are trusted globally to operate in critical applications. “The introduction of these new pumps now provides us with a comprehensive product line, which will allow OEMs to minimize their product development timeline and investment and get to market faster than their competitors.” he says.

GAST – a leading designer and manufacturer of precision air products and member of IDEX Corporation – has launched NEW LubeFree options for their AM series air motors that utilize a proprietary vane material that provides versatility, allowing users the options to oil or not oil the motor.
This new LubeFree option has expanded GAST’s range of 2AM, 4AM and 6AM Series air motors and affords operators the flexibility to modify their maintenance schedules or save money by eliminating oil, lubricator components and system maintenance.
Existing 2AM, 4AM and 6AM Series motors – which are used in a vast number of applications including chemical, paint and sanitary mixing, pump drive, material handling, and other industrial and remote applications – can be upgraded and retrofitted using a new LubeFree vane kit.
As Gast Group’s Andrew Lidington explains, pneumatic motors operating with in-line lubricators have the benefit of extended life, they improve efficiency and acts as a protectorant of surface finishes against dirty or humid inlet air. However, ensuring that motors are regularly oiled can be costly, cumbersome and, in some applications, not even an acceptable option.
“With the LubeFree AM Series option, GAST now has a simple and effective solution. In fact, independent tests have shown more than 10,000 hours of operation in completely oil-less applications and, when lubricated regularly or even occasionally, the motor’s life can be extended by up to 110%!” says Andrew.
There are two LubeFree AM Series options available. The “LL” option offers new vanes with light oil and minimal rust protection, which is ideal for applications where motors rarely get oiled or maintained or where there’s a need to eliminate lubricators completely. For a truly oil-less option where even the slightest contamination cannot be tolerated, the “NLP” option provides a fully oil-free construction with complete corrosion protection for harsh or damp conditions.
The compact and portable 2AM, 4AM and 6AM Series offer operating speeds and power output that can be adjusted to meet the precise needs of your application. Their air throttling and pressure control is not only cost-effective over electric motor controls, but they can also be stalled or overloaded for long periods without damaging the motor. Additionally, they are cool running and have no electrical spark, which makes them ideal for use in hazardous locations.

Gast Group – a leading designer and manufacturer of precision air products and member of IDEX Corporation’s Health & Science division – will be using its stand at Brau Beviale 2016 to promote its JUN-AIR range of compressed air solutions, which are ideal for the beverage dispense and include dedicated models for beer tank pressurisation and postmix equipment.
Commenting, Gast Group’s Andrew Lidington says: “We have many years’ experience in the beverage dispense sector, having worked in partnership with some of Europe’s leading brewers to design and develop medium- and large-scale, cellar-based beer dispense systems.”
He goes on to say that compressed air-based systems provide an ideal solution to the problem of cylinder gas storage, which can have implications for health and safety, storage and replacement.
For beer and/or beverage dispense applications, the Gast Group’s JUN-AIR range of oil-less air compressors offers an unrivalled combination of low noise levels (as low as 47-55dBA when housed in soundproof cabinets), reliability, long life and low maintenance. Receiver tanks are available in stainless steel versions to avoid corrosion and ensure the highest air quality throughout the lifetime of the compressor. Units also feature a unique cooling system and wear-resisting piston rings, and are designed for 100% continuous operation up to 10 bar maximum pressure.
Designed to suit virtually any application and be even quieter and more durable in operation, JUN-AIR latest 86/87R Series Systems provide best-in-class reliability, quality and performance. Their compact footprint makes them easy to install and they are ready to use at point of installation, making them easily integrated into most applications. With low-cost operation in mind, the new systems have also been designed to operate at 8 bar (120psi) for over 10,000 hours before any mechanical maintenance is required.
To provide continuous clean air flow at up to 28lpm, JUN-AIR 86/87R Series Systems also benefit from an integrated double air filtration arrangement, with a 50μm intake filter on the compressor and a 5μm filter regulator for air leaving the tank. Optional ancillaries are also available to further improve the supply air filtration to as low as 0.01μm.
Gast Group will also be promoting other JUN-AIR oil-less and oil-lubricated ranges of clean and quiet compressed air solutions at Brau Beviale 2016. For further information call Gast Group on +44 (0)1527 504040, email gastgroup.uk@idexcorp.com or visit www.jun-air.com.
Mention Gast Group and its JUN-AIR range, and you’d be forgiven for thinking of air compressors that are perhaps best known for being specified for industrial, process, pharmaceutical, laboratory or dental applications.
However, via its French distributor Enerfluid, the Gast Group – a leading designer and manufacturer of precision air products and member of IDEX Corporation’s Health & Science division – has supplied and installed a JUN-AIR OF1202 compressor for “Le grande orgue de Notre Dame de Paris”, the main organ at Paris’ Notre Dame Cathedral which, receiving over 14 million visitors each year, is the most visited location in the city.
As part of the organ’s pneumatic system modernisation – which started in September 2013 – the pneumatic stop tie machines were completely restored and a register system, motorised by high-pressure pneumatic actuators, was supplied to replace the old “Cavaillé-Coll” system that had been used in the organ since its original installation in 1865.
An oil-free JUN-AIR OF1202-40MQ3 compressor was specified for the new pneumatic system thanks to its combination of low operating noise and for providing a supply of clean compressed air – that is free of oil, water and dust – to the air cylinders, which are opening sets registers to ring the pipes installed in the organ.
The JUN-AIR OF1202 compressor serves as the compressed air source for the control system for the instrument, with the amount of air supplying air cylinders which are activated depending on which sound is desired from the organ. For this type of control, a set of pneumatic cylinders have been installed above the Cavaillé-Coll system and provide a force of 200N on an adjustable stroke of up to 6cms and with a working pressure of 1.2bar. This allows for the full Cavaillé-Coll system to remain in place.
Commenting for Orgues Quoirin, engineer Laurent Mesme says: “The JUN-AIR compressor has been installed in the north tower room next to the organ and has actually enabled us to use a very similar technology that Cavaillé-Coll has used for 150 years. It’s just more modern and miniaturised.”
Very little in the transmission of the draw of the original games elements has changed and the operation of the assembly is as quiet as that of the original Cavaillé-Coll pneumatic machinery. Additionally, because the JUN-AIR compressor is enclosed in a soundproof box, it is virtually inaudible.
As Mr Mesme continues, the JUN-AIR equipment has also solved a servicing problem for the customer as the OF1202 compressor can run for several thousands of hours without maintenance, which is essential for this installation.
The JUN-AIR OF range of oil-free, ultra-quiet compressors provides clean, dry air for a wide range of applications. It has an output of up to 260 l/min at 8 bar and the 50/60Hz dual-frequency also provides greater flexibility for exporting OEMs, as it can operate anywhere in the world without the need for modification. Versions are also available to operate at 10 bar maximum pressure.
Like all oil-free compressors from the Gast Group, the OF range is extremely quiet, operating at just 65 to 79dB(A) as free standing units. When housed in optional silent-running cabinets noise levels are reduced to between 46 to 63dB(A).

The Gast Group – a leading designer and manufacturer of compressors and vacuum pumps and a member of IDEX Corporation’s health and sciences division – has launched two completely re-engineered oil-less rocking piston compressors and vacuum pumps which, the company claims, are quieter, more durable and suitable for virtually any application.
The new 86/87R Series extends the company’s already impressive range of rocking pistons and features a new design with a patented crossover chamber design. This causes air to decelerate as it enters the crossover and accelerate as it exits, which dampens the sound and optimises performance while delivering a wide range of pressure level options. The result is a rocking piston that reduces noise output by over 5 decibels compared to previous models and delivers higher pressures, a longer life and greater application flexibility.
As Gast Group’s European sales director Andre Goodson explains, when the company set out to re-engineer its rocking piston compressor it aimed to do more than just increase pressure. “We set out to dramatically reduce sound, enhance flow, improve the compressor’s aesthetics and create a standard footprint for easy retrofit anywhere in the world.”
As a result of this re-engineering, the 86/87R Series features universal dual voltage motors for worldwide operation and its design and construction contains fewer components, causes less friction and has a low exhaust temperature for greater reliability and durability throughout the life of the product.
For OEMs, the new single- and twin-cylinder 86/87R Series features common port locations, additional side ports and can easily retrofit into existing footprints, making it a smart and flexible solution for medical, laboratory, printing, material handling, transportation, food and beverage, environmental and general industrial applications.
Despite its compact size, the 86/87R can reach a maximum pressure of 8.6 bar (125 PSIG) as standard, with the single-cylinder version providing up to 65 lpm (2.3 SCFM) maximum airflow, and the twin-cylinder providing 150 lpm (5.3 SCFM). Vacuum pump versions are designed for operation down to -930 mbar and bespoke compressor models are available on request.
Summarising, Andre Goodson says the new models enhance Gast Group’s already extensive rocking piston range and help create new opportunities in numerous sectors, for applications as diverse as oxygen concentration, beverage dispense, body fluid analysis, automotive suspension, sterilisers, tyre inflation equipment and core drilling.
