DSP Oil Free Rotary Screw Air Compressors-Single Stage VSD

Features

Purity of Air Compression

• Patented HX-18 PTFE-Free coatings ensure purity of air.
• Stainless steel rotors eliminate corrosion and promote the adhesion of the coatings.

Innovative Design

• Patented Rotor Profile Design optimizes the clearances for increased performance.
• Tapered rotors are utilized to compensate for the thermal expansion in the airend.

High Efficiency

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

Maximized Thermal Efficiency

• Patented Stainless Steel Hi-Precooler assists in providing efficient cooling and thermal protection.
• The cooling air path of the Hi-Precooler maximizes thermal efficiency of the cooling system.

Environmentally Friendly

• Patented Oil Mist Remover (OMR) eliminates environmental oil emissions from the gear case, ensuring purity of air compression.
• By recapturing the vented oil mists, oil loss is minimal.
  

Increased Flow = Maximized Power

• Patented “PQ-Wide Mode” gives HITACHI the capability to adjust the speed of operation to provide greater output with lower pressure settings.

HITACHI Microprocessor Based Control

• Lead/lag functionality is standard.
• Operational data recording is standard.
• Schedule Start/Stop operation is standard.
• Instantaneous Power Interruption (IPI) Restart Function is standard.
• PowerSave operation, which saves power by automatically decreasing the unload pressure and averaging the operating pressure is standard.
• Automatic Remote Air Dryer Pre-Start is standard.
  

Major Component Protection

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

Industry Leading Sound Levels & Vibration

• Quiet enclosure is standard.
• Low sound levels allow placement in a variety of locations
• Low vibration design minimizes leak paths. 

Space Saving

• Hitachi manufactures the smallest oil free rotary screw air compressor package in overall dimension, allowing for easy placement in a variety of locations.
• Panel accessibility promotes 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.
