● LOW POWER CONSUMPTION75% of the running cost of an aircompressor is energy cost. V-Majorand V-Compact use less energy thanrotary types, giving substantial costsavings every year.

● LONG TERM RELIABILITYHardwearing reliability under allconditions has been designed intoCompAir reciprocating compressors.

● OIL FREE OPTIONFor applications requiring reliable,clean, 100% oil free air.

● LOW COST MAINTENANCERobust design with low runningspeeds, large bearing surfaces and frictionless valves ensure low maintenance.

● SIMPLE SERVICINGRoutine maintenance does notrequire special tools or specialistpersonnel, reducing downtime and costs.

The V-Major compressor is a slow speed, double acting, watercooled design – lubricated or oilfree, and available for pressuresfrom 1.5 to 20.5 bar g, and powerfrom 55 to 280 kW.

OIL FREE OPTION

Available with oil free cylinders for applicationswhere oil cannot be tolerated in the gas or airbeing compressed. Extended piston rods havenon-lubricated packings and self-lubricatingPTFE piston rings run in corrosion resisting,replaceable, austenitic iron cylinder liners.

EFFICIENT REGULATION

The V-Major has three step regulation for full,part, or no load operation to reduce part loadpower consumption.

SUITABLE FOR HIGH AMBIENTS

These robust compressors work equally wellin ambients of up to 550C. The V-Major isequipped with water jackets and intercoolersto maintain correct running temperatures.Closed circuit cooling systems can beprovided for locations where cooling water is not available.

AVAILABLE OPTIONS

• Vee belt driven

• Direct coupled motor

• Suitable for gases other than air

o Per f o r m a n c e

V-Major and V-Compact – a range to suit all needsCompAir reciprocating compressors have been in

production since the 1920's with a policy of constantimprovements in design and materials. Many

thousands are in service around the world,providing long term, reliable, energy

efficient compressed air in every industryand environment.

With over twenty models available, theV-Major and V-Compact have theversatility to meet a wide range of

applications.

Machines can be supplied for use asvacuum pumps, booster compressors, and for

the compression of gases, including, carbondioxide, nitrogen, methane and biogas.

The product can be suitably adapted to perform inhostile environments.

Additional instrumentation can be fitted quickly andeasily to suit particular requirements.

Compressors can use a variety of power sources,including high or low voltage motors, steam turbines ordiesel engines via a variety of drives. Speeds can beadjusted to match compressor outputs for anyrequirements.

LONG TERM RELIABILITYAND ENERGY EFFICIENCYHard wearing reliability under all conditions has beendesigned into CompAir reciprocating compressors.

Accurate manufacturing tolerances and advancedrunning systems make the range exceptionally efficient.Energy consumption is minimised, using automaticvalve unloading to match variable air demand.

FLEXIBLE INSTALLATION AND ACCESSORIESThe whole range is available with vibration absorbingmounts, and baseplate mounted units orcomprehensive packages, including piping and wiringto minimise installation costs.

A complete range of complementary equipment such asintake filters, silencers, aftercoolers, check valves, anddrive systems are available.
