Efficient at full load, part load and no load conditions, the VS Series™ features expertly designed airends and rotor profiles that offer industry leading turn down and performance. When air is not needed, the VS Series compressors stop running and do not vent to atmosphere; eliminating any waste of compressed air in the system. The “soft” starting capability of the AirSmart™ controller allows the motor to start against a pressurized system at any time and will do so as often as required by the system.
