②
Well-designed structure means easy maintenance - for the draining and cleaning of suction filters.
③
Drain rust is prevented by utilizing an aluminium air tank.

1. Compressor sucks air through an air inlet located at
outer scroll.
2. Compression chamber becomes smaller with the
rotary movement and trapped air is compressed.
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
repeated continuously.

Because the back and right sides are flat and the exhaust extraction is from the top, it’s possible to install the compressor
with two sides close to walls. Installation space is greatly saved.

It is still necessary to secure space for maintenance.
Control Mode setting can be changed between Multi-Drive Control and Pressure Switch Control.
Under Multi-Drive Control mode, the operation of SRL heads is modified automatically, responding to the need of air.
The necessary pressure is maintained producing an optimized, energy-saving performance.
P-Mode:
Similar to conventional Pressure Switch Control, if
maximum pressure is reached, the compressor will
stop operating. When the pressure decreases to the
cut-in pressure, the compressor will restart.
Multi-Drive Mode:
The compressor is automatically controlled to maintain
the necessary operating pressure

Unnecessary power consumption is prevented by
avoiding reaching maximum pressure - and energy
savings are achieved.

Specifications
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.
4. External dimensions indicate the package panel ONLY, NOT including protruding objects such as
discharge outlet.
5. Ambient temperature must be between 0 (at which there is no freeze of drain water) and 40°C.
6. 1.0MPa model is optional for all models except for 3.7kW. Refer ( ) for corresponding data.
7. Hitachi air compressors are not designed, intended or approved for breathing air applications.
8. Motors start with full voltage and on 3 phase source.
