The VWK900-7.5/500P reciprocating compressor with a cast iron three-cylinder unit and a 500 litre vertical air chamber delivers 7.5 HP, 10 bar pressure and an effective displacement of 740 l/min, making it the ideal solution for industrial plants, garages and process applications with high air requirements. Three-phase power supply (400 V) ensures stable operation and efficient filling of the air tank. The 500 l vertical air duct saves floor space but still provides sufficient air supply for continuous work. The low speed (~900 rpm) contributes to quieter operation, less vibration and longer machine life. Powerful compressor with huge air supply for professional use!

Product detailed description

Walter VWK900-7.5/500P Vertical Piston Compressor is an uncompromising industrial station designed for operations with extreme air consumption that also struggle with space limitations. Thanks to the unique combination of a huge 500-liter vertical air receiver and a powerful three-cylinder cast-iron unit, you get a maximum supply of compressed air in a minimal floor space.

Maximum capacity in a space-saving package

The VWK900 model uses 3W three-cylinder technology, which is synonymous with smooth operation and high volumetric efficiency, which is crucial for the stability of production processes with a displacement of 740 l/min.

1️⃣ Three-cylinder cast-iron power (GK series)

3W unit with low speed (902 rpm) – The Low RPM slow-speed concept radically reduces unit heating and piston ring wear, ensuring a lifespan measured in decades.
Cast-iron cylinder construction – Massive cast iron effectively dissipates heat generated during compression and guarantees mechanical stability even under continuous load.

2️⃣ Innovation for Industrial Reliability

New suction filters with steel mesh – The metal insert and robust steel filter cover protect the unit from dirt intake, even in demanding environments like sandblasting and painting shops.
Reinforced valve system – Modernized valves and seals are designed for high flow and pressure of 10 bar, minimizing losses and increasing overall efficiency.

Ideal application and benefits of the VWK900 model

The combination of 5.5 kW power and a 500l tank predestines this compressor for the toughest applications:

  • 🔹 Industrial production lines – Central air source capable of covering high intermittent demands thanks to its large accumulation space.
  • 🔹 Sandblasting and blasting – The 500-liter air supply ensures constant pressure for blasting boxes even during longer cycles.
  • 🔹 Large paint shops – Stable air supply for several spray guns simultaneously without parameter fluctuations.
  • 🔹 Mechanical engineering and assembly plants – Vertical installation frees up handling space for machinery and personnel.

The Valve advises: Ladies and gentlemen, this is the "king of verticals". To build a 500-liter tank vertically and equip it with a 900-liter three-cylinder engine requires solid engineering. The VWK900 will take up the same space in your workshop as a pallet, but will supply the entire production. The three-cylinder "V" runs beautifully smoothly, and the steel mesh on the filters is simply a must for such a giant. Just keep an eye on the ceiling height, this beauty demands its space upwards!
