Oil-Free Rotary Screw Air Compressors 335-900 hp (250-680 Kw)
While most manufaturers top out at 500hp, your compressed air needs don’t, and neither does Hitachi. The SDS Series features two-stage models up to 900hp. Not only do the Hitachi SDS compressors go bigger, they also last longer, thanks to Hitachi’s legendary reliability founded upon a culture of quality. Teachnological innovations found in the SDS Series, such as PLC control, result in a compressor that outperforms and outlasts the competition. With Hitachi, reliable premium air comes standard.
Through the reduction of press pulsations, the discharge silencer reduces noise levels.
Noise Control Cover
Rboust construction aids in the reduction of noise leakage caused by vibration and air turbulence (inlet and vent).
Reliability is increased thanks to a totally enclosed fan-type motor (TEFC)
Oil Capture System
A Oil Mist Capturing System (OMCS) collects oil mist discharged from the gear casing.
Highly Durable Capactiy Regulator Valve
The intake valve is driven by a simple hydraulic piston allowing for a reduced pressure setting range during load, which improves the compressor’s efficiency.
