A duplex bag filter is a type of filter that comprises two single bag filters with ball and butterfly valves connecting their inlets and outputs. By allowing one bag filter to continue operating while the other is undergoing repair, this unique design lowers overall operating expenses.

Two single-bag filters are joined by valves to form a duplex bag filter. Typically, one bag filter is used for filtering while the other serves as a backup during the process. The inlet is located higher than the filter bags.

Filter media enters the working filter bag from the inlet. The clean filtrate runs out of the outlet along the fixed metal basket wall after filtration, while the pollutants are captured in the filter bag.

You can close the filter on the side where the filter bag needs to be changed and activate the backup filter while changing the filter bag. This guarantees the system’s continual filtration and minimizes expensive downtime.

It is also convenient and simple to change the dirty filter bags inside. Drain the filter bag that needs to be replaced after cutting off the water supply. Take off the filter cover, then remove the used bag.

The filter basket should be examined and cleaned as necessary. Reinstall the fresh bag and cleaned the basket in the filter. To prevent it from drying out, inspect the O-ring at the top of the housing and apply food-grade oil.

Reinstall the filter and give it access to the system after making sure the grease’s chemical composition is compatible with the O-ring.

Adopting a filtration system like a duplex filter bag, can significantly reduce downtime and improve the efficiency of your production. Because you always have another bag filter to work.
