The G4 Bag Filter is a medium efficiency multi-pocket synthetic media bag filter providing low resistance combined with high dust holding capacities. Generally used as a pre-filter for higher grades of air filtration, or for use as a simple filter for general applications.

The pockets are produced from thermally bonded polyester fibres that are specifically designed for air filtration. The pockets are retained in a rigid galvanised steel channel.

The G4 Bag Filter is available in a range of standard sizes and pocket lengths and can be manufactured in non standard sizes to suit most applications.
