Industrial Air Compressors
Accessories for Compressed Air
These rotary vane compressors with installed power from 4 to 15 kW are available in ERC or sound reducing AC and AC PLUS versions. PLUS version is equipped with an integrated dryer and a receiver.
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 vanes 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 a perfect holding among the moving parts, cooling and lubrication. 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.
LOW MAINTENANCE COSTS
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.
AUTOMATIC CONTROL OF AIR DELIVERY
Once sucked, the air passes through a valve that regulates the volume of air entering the compressor. This valve is activated automatically by the inside pressure. Thus the compressor adapts to the demand of operating pressure. This means that there is no need of an air receiver and air is pulse-free.
THE CONTROL PANEL
In the ERC version the control panel is simple and practical and includes an hour counter, a start-up and shutdown button, an automatic or continuous operation switch and an emergency button. It is also equipped with safety automatic stops and allows remote start-up procedures.
In the AC version the compressor is equipped with management panel and microprocessor control, MicroC, a programmable system which controls the compressor operation and adapts this to the specific requirements of the air distribution system.
INTEGRATED COMPRESSOR UNIT
Compactness is among the main features of Mattei Compressors; in fact oil chamber and separator, non return and set up valves, air and oil filters are integrated in the compressor.
Thanks to the thoroughness these compressors were designed with, the energy consumption per m³/min is among the lowest of their category. The regulation system is continuous and automatic with off-load operation and allows a very economic adaptation to the installation demands.
The exclusive three-stage oil separating system guarantees a maximum oil carry-over in the air lower than 3 ppm. Moreover, the exchangers the 500 Series is equipped with guarantee compressed air temperatures lower than 7/10 K above room temperature.
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.
Each compressor is equipped with an air cooler and an electronic condensate separator and drain.
These compressors are designed for industrial use 24 hours a day and 12 months a year at constant pressure. Mattei compressors' running often exceeds 100,000 working hours.
Noise level is extremely reduced, in compliance with current regulations.
