    How Rotary Screw Air Compressors Work

    • Two intermeshing rotors in a housing having an inlet port at one end and a discharge port at the other end
    • Most Rotary Screw units are single stage
    • Motors run continuously. The inlet port is closed when the desired PSI is achieved and opens again as needed
    • Lubricant injected into the compression chamber serves three functions
      • Lubricant injected into the compression chamber serves three functions
    • Air exiting the rotors passes through a sump/separator. Directional and velocity changes are used to separate most of the liquid.
    • The remaining aerosols in the air are separated by a Coalescing Filter, resulting in generally 2-5 parts per million of lubricant carryovers
    • Lubricant (carrying much of the heat from air compressing) passes through the cooler before returning to the rotators

    Additional Notes
    • Rule of thumb: every 1 HP produces 4 CFM
    • Advantages
      • Duty cycle can be 100% (80% minimum, designed for continuous use)
      • Quiet
      • Lower cost of compressed air (energy cost)
      • Complete package: air is cooled, filtered through a Coalescing Filter, vibration free
    • Disadvantages
      • Higher initial cost
      • Requires professional maintenance
