Lubricated rotary screw air compressors
50 HP to 500 HP
The Electra-Saver lubricated rotary screw compressors with Turn-Valve by Gardner Denver is 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.

Turn Valve Part Load Technology :
- Patented Turn Valve provides efficient part load capacity.
- Kypho rotor design, coupled with Turn Valve technology, can reduce energy costs as much as 16%.
- Automatically compresses exactly the right amount of air required, assuring maximum efficiency and energy savings.
Direct Drive Non-Geared Airend :
- Increased bearing life (L-10 life in excess of 100,000 hours) due to large tapered roller bearings.
- Permanent airend to motor connection via rigid flange connection for vibration-free operation.
Maintenance Reducing Design Features :
- Simplified access to air/oil separator, requiring removal of only six bolts and no piping to change separator elements. Can reduce maintenance time up to 90%.
- Easy access to air filter mounted directly to the inlet valve.
- Spin-on ten micron full-flow oil filters ensure longer lubricant life and protection for all working parts.
Eliminator Air/Oil Separator (200-500hp) :
- Has TWICE the surface area of conventional separators for better separation and longer life.
- Low carry-over…… less than 2 parts per million, measured BEFORE the aftercooler, at 100PSIG (6.9 bar), full load operation.
Heavy Duty Inlet Air Filter :
- Canister-type filter is standard.
- Removes 99.9% of airborne particulates five microns and larger.
- Extends lubricant life by almost 20%.
AirSmart Controller :
- Easy to use.
- User Selectable Turn Valve or Load/No Load.
- Response time to changes in air demand is instantaneous.
- Built-in ability to sequence up to eight compressors.
