Filtri a Cartucce AIRCOMPACT ATEX_EN

The AIRCOMPACT ATEX cartridge filter has been specifically designed to work in environments that require high protection against explosions in accordance with the ATEX 2014/34/EU regulations.

The AIRCOMPACT cartridge filter is a dust and fumes purifier with automatic backflow cleaning.
The AIRCOMPACT cartridge filter is designed for the use in fumes extraction systems or dust suction systems, working in vacuum mode. Consisting of cartridge filter elements encased in an airtight central body, the AIRCOMPACT cartridge filter can thus be used for plants in the mechanical, chemical, pharmaceutical sectors and wherever processes that produce pollutants, such as smoke and dust, are carried out.


Principle of operation
Polluted air enters the filter through the hopper situated on the lower part of the filter. Due to the sudden decrease of flow speed and the intensive pre-collector, the  greater size particles settle and are collected in the bin below. On the contrary, the lighter and smaller particles rise towards the central body of the filter, inside which the filtering cartridges are placed. The air travels in the filtering cartridges from the outside towards the inside. The dust contained in the polluted air will settle externally, while the air can travel through the cartridges and exit after being filtered.


Automatic compressed air cleaning system
Due to the continuous deposition of dust on the outside of the filter cartridges, an automatic compressed air cleaning system for backflow is necessary: this is ensured by a jet of compressed air which makes the cartridge move in a high-frequency oscillatory way. This phenomenon, called "shock wave" facilitates the back flowing process.

A cyclic programmer manages the diaphragm solenoid valves, thanks to which the cartridge filters are cleaned by sectors. Through the cyclical programmer or PLC it is possible to determine break times and work times. Thanks to this counter current cleaning system, the cartridge filter's efficiency is always maintained at the highest level. Furthermore, after an initial period of work, the value of pressure loss of the filter will remain constant throughout its operational life. A differential pressure switch monitors the level of clogging of the cartridges and consequently it manages the pneumatic cleaning cycle.
