Hydrovane HR04 to HR07
Rotary vane compressors 4 to 7.5 kW – the new Regeneration series
The HR series looks like a Hydrovane, yet inside it has been completely redesigned. It is available as a compressor only, with receiver, with dryer or as a complete package with filters.
At 66 dB(A) it is quiet enough for the point of use, and the air leaves the outlet clean, dry and pulsation-free.
Motor power
4 to 7.5 kW
Pressure
7 to 10 bar
Free air delivery
0.57 to 1.25 m³/min
Sound pressure
from 66 dB(A)
Why the HR04 to HR07?
Low speeds of 1,450 to 2,200 rpm and direct drive without gearbox or belts keep wear low. This allows the compressors to reach more than 100,000 operating hours.
The variable speed HR07E RS adapts its output to demand. Inlet modulation and a reduced blow-down system save additional energy at part load and idle.

Frequently asked questions
How does a rotary vane compressor work?
A rotor with longitudinal slots turns in a cylindrical housing. Vanes slide in the slots; they are pushed outwards by centrifugal force and run on a film of oil. This creates chambers that become smaller as the rotor turns, compressing the air. The rotor is the only moving part and turns slowly with direct drive.
Fixed speed or variable speed (RS)?
A fixed-speed compressor is most economical when it runs at a steady load. If your compressed air demand fluctuates during the day, a variable speed RS compressor continuously adjusts its delivery and saves electricity. On request, we measure your demand with a compressed air analysis and tell you what is worthwhile.
How long does a Hydrovane last?
Thanks to low speed, direct drive and only one moving part, Hydrovane compressors reach more than 100,000 operating hours. The Hydrovane Advance programme offers up to 10 years or 48,000 hours of warranty on the airend.
Who maintains the compressor?
We do. As the CompAir partner for north-western Switzerland, we maintain and repair your system with genuine spare parts and service kits. If your compressed air supply fails, you can reach our on-call service on 062 552 00 88.

Which compressor is right for your business?
Compressed air demand, pressure, operating times and available space determine the choice. We advise you, supply the compressor with air treatment, install the system and take care of service.
