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.
Rotary Vane Compressors – HR 04–07 Series (Overview)
The HR 04–07 Series rotary vane compressors (Hydrovane / CompAir) are medium-capacity, enclosed industrial compressors designed for continuous-duty applications where higher airflow is required compared to the smaller HV series.
🔧 Key Features
Enclosed, compact design → suitable for installation near the point of use
Low noise operation (~66 dB(A)) → quieter than many piston compressors
Direct drive system → no belts/gears → reduced maintenance
Slow-speed operation (1450–2200 rpm) → longer service life
Pulse-free, clean air output → reduces need for extra downstream equipment
Advanced electronic controller (Hydrovane Pro) with:
Timer & pressure control
Fault diagnostics
MODBUS connectivity
Real-time monitoring
⚙️ Technical Specifications
Parameter HR 04–07 Series
Power Range 4 – 7.5 kW (≈5–10 HP)
Working Pressure 7 – 10 bar
Air Flow (FAD) 0.57 – 1.25 m³/min (20 – 44 CFM)
Noise Level ~66 dB(A)

🧠 Design & Working
Uses oil-flooded rotary vane technology (single-stage compressor).
Vanes slide inside a rotor to compress air smoothly.
Oil provides cooling, sealing, and lubrication.
Produces continuous, pulse-free compressed air ideal for steady demand applications.
⚡ Performance & Efficiency
Up to 100, 000+ operating hours due to simple design
Energy-saving features:
Air intake modulation
Reduced Energy Venting System (REVS)
Optional regulated speed (RS) control for varying demand
🏭 Typical Applications
HR 04–07 compressors are widely used in:
Manufacturing units
Pneumatic systems
Packaging industries
Printing & textiles
Laboratories and instrumentation
OEM machinery
✅ Advantages
Reliable continuous-duty operation
Low maintenance (few moving parts)
Quiet and vibration-free
Flexible configurations (with tank/dryer)
Higher airflow than HV 01–04 series
🔄 HV 01–04 vs HR 04–07 (Quick Difference)
Feature HV 01–04 HR 04–07
Power 1.1–4 kW 4–7.5 kW
Flow Low (small tools) Medium (industrial use)
Application Light duty Continuous / industrial
Design Compact open/base Enclosed, packaged
📌 Summary
The HR 04–07 series is a step up from small workshop compressors, offering:
More airflow
Better efficiency
Industrial-grade reliability
They are ideal for medium-scale industries needing consistent compressed air with low noise and minimal maintenance.
