Reciprocating 1 To 20 HP Single-Stage Low Pressure

INDO-AIR Single-stage air compressors are designed for low pressure application. These compressors have cylinders of same size (regardless of the number of cylinders). Robust, overhung design crankshaft for reliability & easy maintenance, solid end connecting rods, high thermal efficiency, inter-cooling, reliable splash lubrication and balanced V-type construction for smooth, vibration-free operation.

Factors to consider in an Air Compressor

  • 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.
