Filtri a Maniche AIRCOM ATEX_EN

The AIRCOM ATEX sleeves filter is designed to work in environments that require high protection against explosions according to the ATEX 2014/34/EU legislation.

The AIRCOM ATEX sleeves filter is a dust and fume purifier with an automatic compressed air cleaning system. It is designed to operate in areas in which high security is required against explosions, it consists of:

  • an upper body extractor with a compressed air cleaning system
  • a central body where the filter sleeves are placed.
  • a lower body with legs, exhaust hoppers and attachments for the input of dusty air.

 

Operating principle:

The AIRCOM ATEX sleeves filter is designed to work in vacuum mode: the dusty air, which enters the filter from the bottom, is subject to an abrupt decrease of speed. As a result the greater size particles settle: the rotary valve will then evacuate them thus ensuring maximum operational reliability.

If dust concentrations are higher, the version with a demister (CC) incorporating a pre-collector is also available The input in this case does not take place in the hopper but, directly in the demister. Alternatively the hopper can be equipped with a rotary valve and auger conveyor (CVS).

 

Cleaning system with backflow compressed air:

The cleaning of the AIRCOM ATEX sleeves filter is guaranteed by the compressed air backflow system, which is automatically managed by the programmer equipped with a vacuum pressure switch that automatically activates the solenoid valves, cleaning a row of sleeves at a time. A cyclic programmer manages the diaphragm solenoid valves, thanks to which the sleeves filters are cleaned by sectors. Through the cyclical programmer or PLC it is possible to determine break and work times. Thanks to this counter current cleaning system, the sleeves 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 sleeves and consequently it manages the pneumatic cleaning cycle.
