1. Compressor sucks air through an air inlet located at
outer scroll.

3. Compression chamber achieves minimum volume at
the center of the scroll and air is pumped out through
the air outlet located at the center of scroll.
4. The suction, compression & discharging process is

No need to change oil and separate the oil from drain. No need to install oil mist filter as well.
2. Well-designed structure means easy maintenance - for the draining and cleaning of suction filters.

If the suction air is thought to contain oil, it is necessary to install an oil mist filter.
Drain rust is prevented by utilizing an aluminium air tank.

Note:
1. Air capacity is converted value at its inlet condition. For guaranteed values, contact your nearest dealer or
HITACHI local representative office.
2. Noise level is measured at 1.5m front, under full-load operation in an anechoic room. It may vary in different
operation conditions or environments.
3. It is necessary to install an air receiver tank for 5.5kW and above models to reduce ON-OFF frequency.
For 2.2/3.7kW models, it is also recommended to install an additional air receiver tank.
