Pulse Jet Bag Filter
The Bag House/Bag Filter is generic name of Air Pollution Control Equipment. It is designed around the use of engineered fabric, filter tubes, envelopes or cartridges in capturing dust, separating dust or filtration process. AIL provides reliable and highly efficient Bag Filters and Bag House systems.

The dust laden gas enters through inlet nozzle and spreads all over the entire cross section of the bag filter. The gas moves up & passes through the bags, enters the clean air plenum through the top open end of the bags. During the passage of the gases through the fabric, the dust is retained on the outside surface of the bags. As the filtration proceeds the thickness of the dust layer on the fabric surface increases resulting in increase in pressure drop across the fabric. This necessitates the cleaning of the bags. Since the air flow is from outside to inside, the bags tend to collapse and are held by the wire cages, whose shape they acquire. The compressed air passing through the solenoid valves injects air at very high velocity for a short duration. This produces a shock wave causing the bag to expand and dislodging the dust cake which falls into the hopper. This unit is generally meant to operate with a pressure differential of 100-125 mmWG.

Af (pre filter / coarse filter / air filter) is a blue-white filtering material mainly applicable for absorbing large dust particle in the air to prevent blockage in medium- and high-efficient filter so as to prolong their service life and efficiency. Since it adopts super-hard fiber which is coated with stable glue, it has higher hardness and density, better pre-filtration effect and higher air flow rate.
