Eight Questions to ask when Specifying an Air Compressor 1. What horsepower are you using on your current air compressor? 2. What Horsepower (HP) and/or flow capacity (CFM) are you looking for? 3. What Discharge Pressure, Pounds per Square Inch (PSIG) do you need? 4. What are the Electrical Requirements of the Installation Site? - Voltage: 110,200,208,230,460, 575 - Phase: Single (1) or Three (3) - Generally air compressors over 7 hp only come in 3 phase. - 220 is standard voltage for homes, also 220 voltage only has single phase capability and will only run up to a 3hp air compressor. 5. What application will the air compressor be used for? What quality of air will be needed? Considerations Usage Aluminum Recip 0 -40% Cast Iron Recip 0-100% ESP Rotary 0-100% Se Rotary 0-100% 6. How often during the day will the air compressor be in use? Ie total hours the facility is open for work activities, and during that time, is the air compressor being used constantly or intermittently? 7. What do you anticipate the FUTURE needs of your air compressor to be? (A good rule of thumb is to oversize a compressor by 25-30% to account for future growth, leakage etc.) 8. Where will the air compressor be located? (indoor/outdoor, clean/dusty, temperature extremes)
