The HWK1500-10/500 reciprocating compressor is equipped with a cast iron four-cylinder unit and a 500 litre horizontal air tank. This model provides 10 HP power, 15 bar maximum pressure, and an efficient 920 l/min displacement, making it an ideal solution for industrial plants, manufacturing facilities, and applications requiring high air pressure. Two-stage compression ensures higher efficiency, lower operating temperature and longer machine life. Three-phase power supply (400 V) ensures stable operation and efficient filling of the air tank. the 500 litre air tank provides a huge air supply for continuous operation without frequent motor switching. Low speed (~720 rpm) contributes to quieter operation, less vibration and higher reliability. Powerful high-pressure compressor with large air supply for industrial use!

Product detailed description

High-pressure piston compressor Walter HWK1500-10/500 represents the absolute peak in the category of industrial piston machines. Thanks to two-stage compression and a robust four-cylinder cast iron unit, this model is capable of continuously delivering compressed air at pressures up to 15 bar. With a massive 500-liter air receiver and extremely low speeds, it is an uncompromising source of power for the most demanding industrial operations.

Two-stage technology for maximum efficiency

Unlike conventional compressors, the HWK series uses a two-stage compression system, where the air is cooled between the first and second stages, which increases efficiency and reduces thermal stress on the entire machine.

1️⃣ Industrial compressor unit of the new generation

Four-cylinder cast iron design – A massive unit guarantees parameter stability and extreme mechanical resistance even in three-shift operations.
Ultra-low speed (725 rpm) – Minimum piston speed radically reduces noise and wear, making the HWK 1500 one of the most durable machines on the market.

2️⃣ Innovations in filtration and cooling

Steel filters with metal mesh – New suction inserts ensure top-notch filtration and protection of valve plates from dirt. The steel filter cover is resistant to mechanical damage.
Optimized thermal management – A large intercooler and fan maintain the outlet air temperature within optimal limits, saving downstream pneumatic components.

Application of the high-pressure HWK1500 model

Thanks to the 15 bar pressure and massive power, this compressor is designed for:

  • 🔹 Industrial lines and factories – Powering automated systems requiring constant high pressure.
  • 🔹 Sandblasting and blasting – Sufficient capacity for continuous blasting work without performance drop.
  • 🔹 High-traffic paint shops – Stable supply of dry and cool air for paint booths.
  • 🔹 Tire services for commercial vehicles – Ideal for high-torque wrenches and inflating large-volume tires.

Valve advises: The HWK1500 is a true giant in the piston world. This is no longer just about volume, but about pressure – 15 bar can break through even the longest pipe runs in the hall. Note that even though the engine has 7.5 kW, thanks to the four cylinders and two-stage compression, the unit doesn't even break a sweat. It runs at a mere 725 rpm, so while you'll be winding down, this Walter will still be in prime condition!
