Proven technology, proven design –
decide for the best solution
Original Busch Standing Filters STF combine different separation mechanisms in a multistage process. The Standing Filter housing is designed as a cyclone in the area of the gas inlet (1). The tangential gas inlet and deflection cone allow the gas or vapour to flow along the inside of the vessel. Coarse particles and liquids are separated at this stage. After passing through the filter insert, the cleaned gas or steam leaves the Standing Filter through the gas outlet (2).
A large opening (3) ensures easy access to the filter insert. The collected condensate can be drained off via the condensate drain (4). The condensate collection chamber can be cleaned via the cleaning opening (5). Other application-oriented versions, e.g. with an automatic condensate drain or in stainless steel, are also available.
Filter inserts for various applications
A wide range of applications for the separation of solids, dusts, vapours, condensates and liquids can be covered by the different inserts.
