Rotary Vane Compressors
Rotary Vane Compressors - HR 04 - 07 Compressors
The Hydrovane HR Series of rotary vane compressors unmistakably Hydrovane but one hundred percent new. It's not so much evolution, but Regeneration.
The Hydrovane Regeneration HR Series is reassuringly familiar on the outside with significant changes on the inside.
Key Facts
50/60 Hz
4 - 7.5 kW
7 - 10 bar
0.57 to 1.25 m3/min
20.1 to 44.1 cfm
Air compressor only or with tank (air receiver) or with air dryer or with all 3 including air filter packages available (left hand side below)
Versatile & reliable by design
Quiet as standard
With noise levels as low as 66 dB(A) a Hydrovane can be located at the point of use.
High quality air
Clean, dry and pulse free straight from the outlet means less downstream equipment required.
Slow speed
1450 - 2200 rpm speed operation results in low noise, low stresses and long life.
Direct drive
No gears, no belts. Up to 100, 000+ operating hours due to its simple integral design.
The Hydrovane HR 04–07 rotary vane compressors are small-to-medium industrial air compressors designed for reliability, low noise, and continuous-duty applications. Here’s a clear, practical overview so you understand what they are and where they fit.
🔧 What is a Rotary Vane Compressor?
A rotary vane compressor is a positive displacement compressor where a rotor with sliding vanes spins inside a housing. Air gets trapped and compressed as the space between vanes decreases, producing smooth, continuous airflow with minimal pulsation.
⚙️ Hydrovane HR 04–07 Series (Key Specs)
These models fall in the 4–7.5 kW range, suitable for workshops and light industrial use.
Power range: 4 to 7.5 kW
