WH Compressors (WH28 – WH50)

Gardner Denver WH Series industrial high-pressure air compressors are high-pressure application compressors designed with an engineering-first approach: to deliver critical compressed air with consistent performance, real energy efficiency and defensible TCO.

High-pressure reciprocating compressors with shaftless motor

Shaftless motor compressors eliminate mechanical transmission losses, delivering 100% motor-to-crankshaft efficiency. No belts, no intermediate gears, no associated wear — zero transmission loss compressors by design.

3-stage double-acting compressors in W configuration

3-stage double-acting reciprocating design: the piston compresses on both upstroke and downstroke. The W configuration enables dynamic balancing, reduces piston ring load by up to 30% and virtually eliminates external vibrations.

Water-cooled compressors for continuous operation

IP56-protected water-cooled motor with efficiency above 97.1%. Self-contained system that reduces radiated heat to the compressor room, operates in harsh environments and virtually eliminates maintenance associated with forced ventilation.

Optimized total cost of ownership

• Compressors with low total cost of ownership
• 3-stage design with only 18 valves (vs. 36 in adapted 4-stage compressors)
• 40-year design life — 40-year lifespan compressors
