Abstract:

An air filter dry cleaning system and method of dry cleaning an air filter is disclosed. The system includes a portable, mostly enclosed cabinet into which an air filter can be placed on two rollers. A blower hose attached to a blower motor blows diffused air onto the filter to dislodge particulate matter. A vacuum hose connected to a vacuum blower motor provides a diffused vacuum air flow to vacuum particulate matter from the air filter. A vacuum air flow connected to the same vacuum blower motor provides a vacuum air flow in the cabinet below the filter. The air vacuum air flow can be connected to a separate detachable dust collection system. Both the portable cabinet and dust collection system can be mounted on wheeled support structures.
