How Cartridge Air Cleaners Work
Not all filters are the same, just like not all homes, businesses, or factories are the same. But most filters work the same right? Not really. Take, for example, a cartridge air cleaner.
Cartridge filters draw in contaminated air, and particles like dust and smoke are captured on the outside of the cartridge. Clean air goes through the cartridge to a fan and is typically recirculated back into the space. The particle build-up on the outside of the cartridge is known as a “dust cake” and enhances the collection performance of the cartridge filter. Cartridge cleaners are most efficient when they have developed a dust layer or dust cake.
But these cartridges should still be cleaned of filtered particles. To do so, the system forces compressed air into the filter in the reverse direction. Smoke and dust are dislodged from the filter and collect in a dust drawer or are transported via a tapered hopper to a barrel for easy disposal. If a system only has one cartridge, the unit must be shut down when cleaning. For units with multiple cartridges, the cleaner can remain running while particles are forced out. This method of cleaning improves performance and extends filter life.
