2 Steps to Select !
1. New Facility
2. Existing Facilities
2a. Compressor always Loading [no off loading]
2b. Compressor can load & off load.
1. New Facility
List all the air operated equipments and devices.
Decide how they are use, all the time or some of the time. Select load or use factor for the devices or equipments.
Example; 15%, 25%, 35%, etc., use factor, if use all the time the use factor will be 100%.
Determine the pressure range and volume of air required for each and every devices and equipments.
The Air Compressor should maintain a minimum pressure at least equal to the highest of these pressures ranges.
2. Existing Facilities
2a. Compressor always Loading [no off loading]
Use formulae:
P1V1 = P2V2
2b. Compressor can load & off load.
Use Formulae:
Air Consumption = Vl / u+l
2c. Using Instruments
Compressor always Loading [no off loading]
Compressor can load & off load.
