Single Bag Filter for Efficient Solid Removal At Low Flow Velocity Range

Single bag filter consists of a filter housing, a support basket and a filter bag and is suitable for solid filtration applications at low flow velocity range. In addition, we also offer multi bag filters and duplex bag filters to meet your diversified filtration demands.

Material: carbon steel, SS 304, SS316, special materials are available upon request.
Single filter bag structure, PE, PP, PA, PTFE and stainless steel filter bags for your option.
Filter rating up to 0.5 – 1000 μm, flow rate up to 250 GPM
An adjustable bracket is provided, as a result, the height of the filter is adjustable.

Working Principle

The position of the single bag filter inlet is higher than that of the filter bag. Filter medium flows into the filter bag from the inlet. After filtration, the impurities are trapped in the filter bag, and the clean filtrate flows out from the outlet along the fixed metal basket wall.

The filter bag needs to be replaced when the impurities on the filter bag build up into a filter cake and the differential pressure reaches 0.05-0.1 MPa. When replacing the filter bag, the filter system must be shut down for a period of time, open the pressure relief valve and filter cover, and reinstall the filter after replacing the filter bag. Filter bags can be reused after cleaning, but need to be replaced when damaged to a certain extent. Filter bags can be reused after cleaning, but need to be replaced when being damaged to a certain extent.

Maintenance

The filter bag needs to be replaced when the impurities on the filter bag build up into a filter cake and the differential pressure reaches 0.05-0.1 MPa.
As bag filters are frequently used, trapping a large quantity of impurities, as a result, regular inspection, maintenance and repair are required even the differential pressure is small.
If the gasket is deformed, replace with a new one immediately.
