Rotary Screw Compressor Considerations
- One HP is the force needed to lift 550 lbs. one foot in one second.
Cubic Feet per Minute (CFM)
- CFM is the amount
or volume of air velocity that passes through a medium. Think of a water hose where you can measure the quantity of water that is possible to pass through in one minute.
Pounds per Square Inch (PSI)
- PSI is the measure of pressure
that a compressor is able to produce, in pounds, per square inch of space. Going back to our water hose example, PSI would be the amount of pressure at which the water (or air) comes out of the hose. Without a nozzle, it may trickle out, while one with a fine tip can blast grime out of concrete.
If you ever had a kink in a line, then you would experience no CFM, while pressure behind the kink (PSI), would be building and possibly rupture the line.
It's important to pay attention to both CFM and PSI requirements of air equipment so you choose a powerful enough compressor for the job.
- You need to choose single-phase or three-phase. Single-phase electricity is found in residential settings while three-phase electricity is most typically found in industrial locations & settings.
Consult with your electrician and local codes to determine which type you have.
