Bag & Bag Housing

    Duo-Bag Series Filter Bags

The innovative Duo-Bag series offers a highly elegant design to substantially increase the capacity of the filter bag.

The unique design of Duo-Bag filter bags provide larger surface area than typical filter bags,

which allows the fluid flowing between the inner and outer media cylinders.

PPDB series bag filters can easily retrofit most standard bag filter housings.

To take advantage of PPDB series in applications where bag filter bag housings are currently in use,

end-users can simply remove the existing bag basket as well as replace it with a PPDB basket and a PPDB bag.
