Why
is Compressed Air Useful?
The compressed air energy contained within a balloon is equal to the energy required to inflate it. The energy is stored as pressure.
When the balloon bursts, the pressure equalizes and the energy is released. This energy can be used to complete work.
Just like an engine of a car, as the pistons rise, they press the air into a tighter space which creates pressure. Compressors can have 1 stage or 2 stages of compression.
is compressed once and then discharged. Max Pressure = 130 PSI. Two-Stage Piston air is discharged once in a low pressure side and again in a higher pressure side before discharge. Max pressure = 175 PSI.
- Low Price
- Easy to Understand
- Simple to Maintain
Duty Cycle: Piston compressors generate a lot of heat during the compression process, they are restricted to the
amount of time they can operate. This is what we can the "duty cycle". Single-stage pistons normally have a 50%
duty cycle and two-stage pistons have a 75% duty cycle.

Rotary Screw Compressors
Variable Speed Compressors Quiet Rotary Screw Compressors
Rotary screw compressors act like superchargers in a sports car. Two helical rotors match each other and rotate together. As they do, air is squeezed into a smaller and smaller cavity, creating increasing pressure. A thin film of oil lubricates the rotors and keeps them from overheating.
- Runs cooler so it can operate continuously - More stable pressure - Air always available when you need it - Low sound level- 7 times quieter than a Piston - Better work environment for your team - Lower Oil Carryover - Reduces product contamination - BEST choice for painting - Better for the environment
To size the compressor, we need some basic information.
1. Maximum Operating Pressure: - Look at the pressure ratings on the equipment - Are there any known pressure issues?
2. Total Air Requirements (Total cfm) - Add up all the cfm ratings on the equipment (they are listed on all tools) - Do you want to wait on the compressor for air? - How many tools are you using at once? - Have existing compressors and storage tanks?
Calculate the Correct Air Requirements 1. Determine the total air requirements (in cfm) for all equipment 2. Make adjustments: - Add 10% for leaks and growth in business - Use consumption x 1.5 for piston compressor - Use consumption x 1.0 for rotary screw 3. Determine final air requirement in cfm for the equipment 4. Check your air requirements with the "benchmarks" below on the number of workers
