Safe change filter housings Technical features Product Canister safe change filter housings are used for the tight accommodation of filters subject to air flows containing noxious, toxic, radioactive substances, etc. They are especially used in industrial plants, laboratories, and process applications. Their main feature is to allow the maintenance personnel to safely replace the exhausted filters, both absolute and activated carbon. In fact the operator never touches the filters because they are insulated inside a protection bag where they are sealed and then disposed of. This operation is also very safe for the surrounding environment. The new filters are then handled without any direct contact. They are pulled out of their protection bags (bag-in, bag-out procedure). Canister housings are made of strong galvanized sheet steel, welded, externally and internally varnished with decontamination paint (V1.Z); on request we can also supply the product with an AISI 304 (SS) stainless steel structure. They are fitted with a side inspection door with sealing handles, there are also pressure ports, centering devices and filtration element locking and other features to guarantee extremely safe use and operation. ✓ Product ready in Stock Technical draft
