Cast iron piston compressor HWK1500-10/500P-15P input power 7.5 kW, suction power 1120 l/min, pressure 15 bar, air receiver 500 l, voltage 400/50 V/Hz
Code: HWK1500-10/500P-15PRelated products
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.
