  • Page 13: Operating Principles

    Operating Principles Air Compression The Gas Engine Driven 30 CFM Air Compressor uses a VMAC designed and manufactured flooded lobe, rotary screw compressor. The oil filled compressor housing contains 2 rotors. Compression occurs when air (at normal atmospheric pressure) enters a chamber where it is trapped between meshing rotor lobes.

  • Page 14: Spark Arrester

    Filtration VMAC rotary screw compressors are designed and machined to exacting tolerances. Foreign particles entering the compressor can damage system components such as seals, bearings, rotors, as well as the inside of the housing, resulting in performance losses and reduced system life.

  • Page 15: Extreme Climates And Elevation

    Cold Environment Operation The Gas Engine Driven 30 CFM Air Compressor system is not designed or recommended for use in cold climates (below 0 °C / 32 °F) unless equipped with a VMAC cold climate kit (P/N: A500044). Cold Environment Recommendations Ensure the following conditions are met before starting the compressor: •...

  • Page 16: High Altitude Operation

    For engine oil recommendations in temperatures above 40 °C (104 °F) refer to the Honda GX390 Owner’s Manual supplied with the system (VMAC P/N: 1901066). Failure to follow the information supplied in the Honda Owner’s Manual may result in poor engine performance or engine damage.
