BFOS is a filter housing manufactured by the German company FUHR and is one of their most popular filtration housings. The filter housings are made of stainless steel and can be used for filter bags in size 1 or size 2.
The construction consists of a container with welded bottoms and a lid on top, which is attached with hinges and sealed tightly with an O-ring. The liquid is supplied via a pipe on the side and discharged through a pipe at the bottom of the filter housing. The filter bag is easily mounted in the filter housing and can be easily replaced after use.
