Cylindrical filters have application uses from vacuum cleaners to nuclear submarines. Frame construction of metallic or non-metallic materials and diameters from inches to feet are available. Cylindrical filters can be ordered with HEPA-SEP® or HEPA-PLEAT II® packs in most efficiencies. Filter packs can be solid or cartridge shaped. They are primarily used in hospital applications and other special installations to save on construction costs while maintaining a clean environment.
Vectors are quarter-round filters with radius face designs that fit between the wall and ceiling.
