Hitachi Industrial DSP Oil Free Rotary Screw - Two Stage VSD Air Compressors

Hitachi two stage VSD DSP oil free rotary screw air compressors provide contaminant free compressed air for a variety of manufacturing facilities. Hitachi's rich experience and technological breakthroughs in the development of industrial-class air compressors has made the industrial two stage VSD DSP oil free rotary screw air compressors ideal for all industrial applications.

Hitachi Two Stage VSD DSP Compressors Features

Go through the following key features of industrial two stage VSD DSP oil free rotary screw compressors to learn why Hitachi DSP air compressors are known for reliable and energy efficient performance:

Purity of Air Compression

  • Patented HX-18 PTFE-Free coatings to ensure purity of air.
  • Stainless steel 1st and 2nd stage rotors to eliminate corrosion and promote adhesion of the coatings.

Innovative Design

  • Patented Rotor Profile Design to optimize the clearances for increased performance.
  • Tapered rotors to compensate for thermal expansion in the air end.

High Efficiency

  • Matched HITACHI inverter and EPAct Efficiency motor to allow for low power consumption and stable pressure control.

Maximized Thermal Efficiency*

  • Patented Stainless Steel Hi-Precooler to assist in providing efficient cooling and thermal protection.
  • Cooling air path in the Hi-Precooler to maximize thermal efficiency of the cooling system.

Environmentally Friendly

  • Patented Oil Mist Remover (OMR) to eliminate environmental oil emissions from the gear case, ensuring purity of air compression.
  • Minimal oil loss through recapturing of the vented oil mists.

No Inlet Valve Design

  • The patented No Inlet Valve Design ensures that vacuum is not generated at the air end inlet and succeeds at obtaining stable sealing performance even at slow running speed.
  • No rebuild or replacement parts are needed, which saves investment in consumable and maintenance items.

HITACHI Microprocessor Based Control

  • Standard lead/lag functionality.
  • Standard operational data recording.
  • Standard schedule Start/Stop operation.
  • Standard Instantaneous Power Interruption (IPI) Restart Function.
  • Standard Power Save operation to save power by automatically decreasing the unload pressure and averaging the operating pressure.
  • Standard Automatic Remote Air Dryer Pre-Start.

Major Component Protection

  • To protect major components, the standard Motorized Isolation Valve (MIV) automatically closes the discharge when the DSP air compressor stops.

Industry Leading Sound Levels & Vibration

  • Standard quiet enclosure.
  • Low sound levels to allow placement in a variety of locations.
  • Low vibration design to minimize leak paths.

Space Saving

  • Hitachi manufactures the smallest oil free rotary screw air compressor package in overall dimension to allow easy placement in a variety of locations.
  • Panel accessibility to promote space conservation.

In-House Manufacturing

  • Hitachi manufactures most of the major components of the DSP air compressors: HITACHI Airend, HITACHI EPAct Efficiency Motor, HITACHI Microprocessor Based Control and HITACHI Enclosure.

* Available for 125 psig air-cooled models.
