The newly enhanced airend has improved efficiency over its predecessor and increased bearing life over 50%. Low Sound, Compact Size and Ease of Maintenance.


Gardner Denver Integra: Maximum Reliability and Control in an Integrated Compressor Package. Includes Energy Efficient Airend, AirSmart control, Low dBA level, and Easy Access to all Components. The Integra is offered from 15-50hp and comes in a small, compact footprint.


Gardner Denver Electra-Screw: Value with field proven reliability. The Gardner Denver Electra-Screw 40, and 50hp rotary screw compressors provide an economical solution to your compressor needs. Standard features include modulating capacity control system and microprocessor based system control. Optional features include quiet enclosure and wye-delta starting for the 40/50hp units.


Electra-Saver II series are workhorse air compressors that range from 15hp all the way to 200hp. These rotary screw 60Hz compressor packages are Direct Drive with oversized airends and bearings insuring energy savings and long life.


Gardner Denver Electra-Saver with Turn-Valve: The Industry Standard for Variable Displacement Compressor Technology. With Energy Efficiency models with sizes up to 500hp, the patented Turn-Valve provides electricity cost savings when demand for compressed air fluctuates. These variable displacement compressors operate on the basic principle that air is drawn through the fully opened inlet by the “un-meshing” action of the rotating screws. This technology matches the compressor output to the compressor air demand. For more information request a quote today!

EnviroAire T/VS Series oil free compressors offer industry leading performance in the most demanding applications through high efficiency components, low pressure losses, low temperatures and economical control.


V & HV Series Rotary Vane Air Compressors

Rotary vane compressors are the unique alternative to rotary screw compressors. All hydrovane rotary vane compressors are direct drive and operate at slow rotational speeds. Hydrovane compressors are typically quieter, smaller, and have less moving parts than a rotary screw. For fluctuating demand applications, hydrovane compresors are also available with regulated speed drives, which greatly reduce energy costs.
