DWTBF
DWTBF Double bag filter housings with manual switch between the two
DWTBF Double bag filter housings are made of stainless steel and are equipped with a manual switch for parallel or single operation. This allows for a filter bag exchange without process interruption, ensuring a constant operation. Depending on the flow rate and medium, different types of connections can be delivered, e.g. flange, screwed pipe connection DIN 11851 or pipe thread. The versions with a central switch-over handle are equipped with 3-way-ball-valves. The versions with butterfly-valves are equipped with a central T-piece for in- and outlet.
Three different sizes with filter areas ranging from 2 x 0,1 m2, 2 x 0,25 m2 and 2 x 0,5 m2 are available. Special accessories such as discharge-ball-valves and vent valves, volume reducer and manometers can also be supplied. Additional optional instruments availablefor monitoring are different pressure gauges and pressure detectors.
