Bag filter consists of a number of tubular filter bag sleeves arranged in a square or rectangular matrix. These sleeves are supported from inside on steel wire cages to prevent them from collapsing .The dust laden air is drawn through the filter bag sleeves   by an externally connected Centrifugal Blower in its downstream end and thereby dust gets collected on the outside surface of the filter bag sleeves. The sleeves are periodically cleaned by short blasts (pulse) of compressed air.

These blasts are in the opposite direction to the flow of dust laden air. This reverse flow flexes the fabric bags away from the cages and loosens the dust cake collected on to bags and the process is repeated for every row of bags. The filter media (standard fabric) is synthetic and non-woven needled felt. The suiting filter fabrics/media are available for different air/gas temperatures (upto 200 deg) and as per the application requirement. Apart from High ratio (Pulse jet)Bag filters, low ratio Bag filters of mechanical shaking type are also offered by us for specific applications.
