» How often the compressor is used and how it is used
» Short list in-plant compressed air application. Make a list of equipment in the plant Consuming compressed air and expected air flow requirement in ‘CFM’ and the required pressure in ‘PSI’
» Consider the duty cycle of your compressors as most compressors are not meant to run all the time.
» Decide on the size/capacity of the tank. The more use of equipments means the need for larger tank. Choosing a larger tank than the need will ensure optimum use of the Compressor.
» Consider 10% more capacity compressor to compensate the air misuse or leaks and pressure drop in the system.
» Decide on the continuous run style or start-stop style compressor. ( A compressor that runs continuously, but only compresses air as per demand or a compressor that fills the tank and stops until low pressure signals a start).
» Consider the accessory which is to be installed with each compressor.
» Other like maintenance, life expectancy, trouble shooting (also know the manufacture network/ regional offices), repair costs, etc.
» Bare compressor
» Air Suction Filter

» Air Dryer : For dry or moisture free air – Refrigerated; Heatless Air Dryer
» Air Dryer : Condensate Drain Trap : Automatic Type
» Low Oil Level Switch
» Sound Enclosures : For low noise
» Control Panel – for centralized control & display of parameters
» Compressor also available as : Base Plate Mounted – Portable, Tailor- made package
Two – stage air compressors are designed for Medium Pressure Application and made of Heavy – Duty components to give the maximum performance. These compressors are having two different size cylinder bores. Robust overhung design crankshaft for reliability & easy maintenance, solid end connecting rods, highly thermal efficient inter cooling, totally reliable splash lubrication & balanced V-type construction for smooth vibration free operation.
Two Stage Medium Pressure Compressors ( 7 – 17.5 kg/cm2)
