Hydrovane Advantages

Maximise energy consumption

No gears and no belts mean fewer components to maintain, fail or replace, and no power loss.

Low noise levels

With noise levels as low as 62 dB(A), there aren’t many quiet air compressors silent enough to be located at the point of use.

High quality air

Hydrovane compressed air is clean, dry and pulse free straight from the outlet, with no receiver required as standard. Oil carryover (OCO) is typically less than 3 ppm.

Long lifespan

Reliable technology with fewer moving parts allows up to 100,000+ operating hours without the need for an expensive Air End change or refurbishment, when correctly serviced with genuine parts.

Package options

Both horizontal and vertical compressor formats are available as standard, enclosed or open, offering our customers a real choice when it comes to finding the solution.

Genuine parts

Maintenance and services conducted by Direct Air are carried out using genuine Hydrovane spares, ensuring your compressor is eligible for the Advance 10 Warranty.

Energy Saving

Hydrovane Regulated Speed compressors can reduce your energy bills by up to 50% with a typical payback in 3 years*.

Regulated speed compressors from Hydrovane (7.5 to 45 kW) can efficiently and reliably meet the varying air demand found in the majority of air systems, by automatically controlling air output to meet your exact requirements. The right regulated speed compressor in the right application delivers significant energy savings and a stable air supply at a constant pressure.

Rotary Vane principle

So how does a Hydrovane work?

1. Air is drawn through the intake valve

2. Air is contained between the rotor and the stator wall

3. Air is compressed by decreasing volume, Oil is continually injected to cool, seal and lubricate

4. High pressure air passes into the primary oil separator

5. Remaining traces of oil are removed in a fina separator element, providing high quality air

6. System air passes through the aftercooler, removing most of the condensate

7. Oil is circulated by differential internal air pressure. It passes through an air-blast oil cooler and filter before being returned into the compressor

8. Air flow is regulated by an inbuilt modulation system
