Portable diesel air compressor rental Bérgép Kft.

Compressor element

The compressor casing houses two screw-type rotors, mounted on ball and roller bearings. The male rotor, driven by the engine, drives the female rotor. The element delivers pulsation-free air. Injected oil is used for sealing, cooling and lubricating purposes. 

Compressor oil system

The oil is boosted by air pressure. The system has no oil pump. The oil is removed from the air, in the air/oil vessel at first by centrifugal force, secondly through the oil separator element.

Regulation

The compressor is provided with a continuous regulating system and a blow-down valve which is integrated in the unloader assembly. The valve is closed during operation by outlet pressure of the compressor element and opens by air receiver pressure when the compressor is stopped. When the air consumption increases, the air receiver pressure will decrease and vice versa. This receiver pressure variation is sensed by the regulating valve which, by means of control air to the unloader and engine speed regulator, matches the air output to the air consumption. The air receiver pressure is maintained between the pre-selected working pressure and the corresponding unloading pressure.
