Hitachi DSP series oil free screw air compressor


Power: 15 - 240 kW

FAD: 2.0 - 40.5 m³/min


1)  Provides "CLASS 0" level clean oil-free compressed air: Tested by a third-party certification body (TÜV) according to ISO 8573-1, proving that Hitachi oil-free compressors meet the "CLASS 0" standard for compressed air quality and have been certified.

2)  High-performance air end: Oil-leak-proof drive shaft and seals, corrosion-resistant and durable stainless steel rotors and timing gears.

3)  PC end-pressure control, Patent No. (Japan): 4425768: Predicts terminal pressure based on air consumption, reduces outlet pressure during low-load operation, and decreases power consumption.

4)  PQ expansion mode Vtype (22-75xw): Variable frequency drive system enables operation with low pressure and high capacity or high pressure and low capacity.

5)  ECOMODE mode (standard machine) M:e: Automatically lowers unload pressure based on compressor load ratio, achieving energy savings.

6)  Energy saving with unique mid-stage air release through variable frequency Vwe: No suction throttle valve; by releasing air simultaneously from the high-pressure and intermediate stages, ensures shaft seal stability without maintenance for the suction throttle valve.

7)  Long lifecycle and easy maintenance: High-quality spare parts and global after-sales service.

8)  Cost reduction: The cost of DSP single-stage compress is much lower than two-stage compress, with major overhaul costs at 60% of those for two-stage compress.

9)  Low-pressure specification for higher discharge volume: Adjust the air compressor according to the required pressure, saving energy while improving work efficiency.
