Abstract

A filter assembly comprising: an inner cartridge; an outer cartridge; a cartridge flange end cap comprising a base peripheral flange and centrally-located cylindrical raised base; a cartridge flange top cap comprising a ring portion defining an opening, a peripheral flange; whereby one end of the inner cartridge is held around the centrally-located cylindrical raised base and other end of the inner cartridge is received by the opening in the cartridge flange top cap; and one end of the outer cartridge engages an inner wall of the base peripheral flange and other end of the outer cartridge engages an inner wall of the peripheral flange.

IPC Classes  ?

• B01D 46/24 - Particle separators, e.g. dust precipitators, using rigid hollow filter bodies
• B01D 46/00 - Filters or filtering processes specially modified for separating dispersed particles from gases or vapours
• B01D 46/56 - Filters or filtering processes specially modified for separating dispersed particles from gases or vapours with multiple filtering elements, characterised by their mutual disposition

Abstract

An air filter apparatus includes at least one frame that is configured to receive a filter media, and at least one sensing mechanism for sensing contamination of the filter media. The sensing mechanism can include a wave emitter and a wave detector. The wave emitter and the wave detector can be arranged so that the wave travels along a path that is substantially parallel to outer faces of the filter media. The wave detector can be located at a first edge of the frame, and the wave emitter can be located spaced apart laterally from the wave detector at a second edge of the frame, so that waves from the emitter can travel along the path through and laterally across the filter media towards the detector. The path can be substantially perpendicular to the general direction of air flow within the filter media.

Abstract

An air filtration unit is provided with a replaceable media cartridge to reduce the time, material, and labour costs required to maintain the filtration system. A housing portion includes a mounting flange, a supporting frame, and a collar for receiving a replaceable media cartridge. The replaceable media cartridge slides into the frame. At least one cap ensures that air flows through the cartridge and may provide a handle for easy removal and replacement of the cartridge.
