Bag filter is one of the most efficient and cost effective dust collector models. In baghouse filter, the dust filled air stream passes through fabric bags that filter the dust particles. Bags are made of different material such as woven or felted cotton, synthetic, or glass-fiber. The bags are cleaned manually by giving a manual shaker mechanism.

The dust from the bags is collected in the bin below the hopper. rotary airlock or double gate dampers are given so that the air is not leaked from bottom.

Selecting Bag Filter Bag Media
Important considerations while selecting fabric filter material for bag filter:

    Temperature of incoming dusty air stream
    Moisture levels in the collector and hydroscopic nature of dusts
    Electrostatic nature of dust particles
    Abrasion levels caused by dust particles
    Acid chemical resistance and Alkali chemical resistance of fabric
    Fabric’s capability to release dust cake easily
    Fabric’s permeability to allow air to pass
    Size of dust particles
    Fabric cost
