Hitachi SDS Series 335-900 HP

 

 

 

While most manufacturers top out at 500hp, your compressed air needs don’t, and neither does Hitachi. The SDS Series features twostage 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. Technological 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.

Applications

  • Textiles
  • Electronics
  • Air Separation
  • Food and Beverages
  • Discharge Silencer - Through the reduction of press pulsations, the discharge silencer reduces noise levels
  • Noise Control Cover - Robust construction aids in the reduction of noise leakage caused by vibration and air turbulence (inlet and vent)
  • Main Motor - Reliability is increased thanks to a totally enclosed fan-type motor (TEFC)
  • Highly Durable Capacity 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
  • Oil Capture - An Oil Mist Capturing System (OMCS) collects oil mist discharged from the gear casing
  • NEW Air Block - Through the reduction of press pulsations, the discharge silencer reduces noise levels

    1. 3-D Screw Rotor (patented) - A new rotor design compensates for thermal deformation distribution due to air temperature differences from inlet to outlet. The rotors also received a new, patented resin coating, increasing durability.

    2. Long-Life Bearings - Precision machining, high quality materials, advanced analysis, and lubricating theory are used in the design of the SDS Air Block bearings ensuring increased longevity.

    3. Highly Reliable Shaft Seal - The entrance of oil mist into the compression chamber is reduced through the use of a wear-resistant floating seal and high quality thread seals.
