The MF and MFH SERIES Manual Filter is the least expensive type of filtering device. It has a main upper inlet plenum that holds the suspended filter bags. The bags can have a zipper or velcro bottom for manual emptying of the bags themselves, or they can be connected to a lower plenum in the MFH SERIES. The lower plenum will have hoppers attached to to it that empty into 55 gallon drums. With the MFH SERIES Filters, a manual or automatic slide gate is used to close the hopper to be able to empty the drums while the system is running. Both models are custom designed for the air volume and space requirements.
