ABSTRACT:
An improved air cleaning filter is disclosed. This device is primarily intended for use as an industrial vacuum cleaner, although the system can be adopted for stationary air filtering systems. The vacuum exhaust is fed into a housing that holds a quantity of water. The polluted air is then forced through the water, which traps most of the dust and dirt. As the clean air is exhausted, however, minute dirt and water particles tend to be sucked up as well. These particles are caught using a baffle structure that feed air into a plenum. A dust trap is suspended in the plenum to catch more stray particles. As this air is exhausted from the plenum, it passes through another set of baffles, which catch any remaining particles. Clean, dry air is then exhausted through a port at the rear of the housing. This system cleans the air so thoroughly, there is no need to cover the exhaust with paper filters. The device is made of high strength plastic.
