Structure of High Performance Airend

Stainless Steel Rotor Airend

The rotor material, machined by high-precision grinding, is a
special stainless steel that excels in corrosion resistance and
durability. In addition, to minimize internal leakage, the rotor is
mirror finished to ensure proper clearance, taking thermal
expansion during operation into consideration.

High Performance Rotor Profile

Rotors exposed to discharge temperatures of 300° C or more in
single-stage machines and 200°C or more in two-stage machines
undergo significant thermal expansion.

Premium Air Quality

True Oil-Free Air at Class 0 Level
Test and analysis of condensation of oil in the discharge
air of Hitachi Oil-free Screw Compressor (DSP) are
implemented by third party (TÜV) based on ISO8573-1 ISO 8573-1
standard. By the test result, oil contained in the
discharge air of Hitachi DSP is proved and certified as

What compressors are used for

- The compressors listed in this catalog can only compress air. Never use them to compress gases other than air.
Doing so may cause fire, damage, etc.
- The compressors cannot be used for respiratory equipment for breathing compressed air.

Installation location
- Install the compressors indoors. Do not use the compressors in a place where it is exposed to moisture such as rain or steam.
Doing so may cause fire, electric shock, rusting, or decrease in product life.
- Use the products in a location where there are no explosive or flammable gases (acetylene, propane gas, etc.), organic solvents,
explosive dust, or fire nearby. Failure to do so may result in fire or accident.
- Do not use the products in locations where corrosive gases such as ammonia, acid, iron, sulfurous acid gas, etc. are present.
It may cause rusting, decrease in product life, or damage.

Terms of use
- Please read the "Instruction Manual" carefully before use and use the products correctly.
- Never modify the products or its parts. Doing so may cause damage or malfunction.
