Operating Principle

The air is sucked by means of a filter and passes through a modulating proportional valve that regulates the air delivery according to the demand. This valve automatically maintains the working pressure at constant levels.

Therefore, the air enters the compression chambers or vanes that the stator, the rotor, the blades and the covers have formed. This rotor is installed eccentrically to the stator and is equipped with longitudinal grooves in which the blades slide. It is the centrifugal force that pushes the blades against the stator's wall.

An efficient oil injection system guarantees cooling, lubrication and a perfect holding among the moving parts. An oil film on the stator's inside surface prevents the moving parts from wearing by avoiding a direct contact with the blades..

Air compression is triggered by the volume reduction of the vanes in the stator during rotation. By passing through mechanical and coalescing separation stages, the mixture of compressed air and oil is purified until the maximum oil carry-over in the air does not exceed 3 ppm (parts per million).

Finally, the air is cooled in the radiator and the condensate is eliminated by a condensate drain.

Advantages

AIR QUALITY

The exclusive three-stage oil separating system guarantees a maximum oil carry-over in the air lower than 3 ppm. Moreover, the coolers the 3000 Series is equipped with guarantee compressed air temperatures lower than 7/10 K above room temperature.

FULLY EQUIPPED

Each compressor is equipped with an air cooler, an electronic condensate separator and drain and a Micromat control system.

SIMPLE DESIGN

The design essentially consists of a rotor that eccentrically rotates in a larger diameter stator.

The rotor is supported by bushes and not by roller bearings.

REGULATION SYSTEM

Mattei compressors are equipped with a double regulation system: continuous with modulation, automatic with off-load operation and decompression for energy saving.

DIRECT COUPLING

This is obtained with a flexible coupling between motor and compressor, without any need for belts. It is without gears or roller bearings needing maintenance.

MODULATION OPERATING MODE AT CONSTANT PRESSURE

Thanks to a modulating proportional intake valve that supplies air at constant pressure, these compressors can even work without receiver.'

OVER 50,000 HOURS BLADE LIFE GUARANTEED

An oil film on the stator's inside surface prevents the moving parts from wearing out by avoiding a direct contact with the blades.

SIMPLE AND ECONOMIC MAINTENANCE

Cost Analysis after 40,000 Working Hours

Maintenance operations only include changing the oil at predetermined intervals, cleaning or replacing the air filter and cleaning the radiator. The separator filters are substituted every 10,000 working hours, with significant savings.

OPTIONAL: HEAT RECOVERY KIT

The heat recovery system, that is integrated in the compressor's cooling system, consists of a plate that exploits the oil heat to warm up water for industrial and sanitary use.
