A system for cleaning a filter mounted over an intake opening of an air handling unit. A conduit is secured to an elevated location of the unit and includes a plurality of spaced nozzles arrayed against the filter. A supply tube connects to the conduit for supplying a pressurized fluid through the nozzles in order to clear debris from an exterior of the mounted filter. The pressurized fluid includes either of water or compressed air provided from any of a source or a supply reservoir. A pump is incorporated into the supply tube for pressurizing the fluid. A filter incorporated into the supply tube filters the pressurized fluid prior to delivery to spray issuing conduit.

A blood clot removal method for removing blood clots from the vascular system of a patient, the blood clot removal method carried out on an implantable device in the patient's body and comprising: allowing a blood flow through a passageway between a first side wall and a second side wall, filtering blood clots with a filter provided in the blood flow passageway, and cleaning the filter with a cleaning device, wherein the cleaning device is moved from the first side wall towards the second side wall to move blood clots away from the blood flow passageway.

An apparatus and a method are provided for an air box with an integrated air filter to communicate air flow from an exterior of the air filter to an air intake of an automobile engine. The air filter comprises a filter material that surrounds at least a portion of an interior cavity of the air filter. An end cap is affixed to a distal end of the filter material, and a wire support extends along at least a portion of the exterior surface of the filter material. The air box comprises a housing portion and a mount portion. The housing portion is configured to direct air drawn through the filter material into the interior cavity of the air filter and then into the air intake of the automobile engine. The mount portion is configured to support the air box and the air filter once installed within an automobile engine bay.

A filter oil composition and a method for removing airborne molecular contaminants from air are provided. The composition includes a first portion comprising paraffinic oil by volume of the composition, a second portion comprising polyalphaolefin (PAO) by volume of the composition, and a third portion comprising red dye by volume of the composition. Applying the filter oil composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing filtration of air passing through the filter. The composition generally is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at a normal operating temperatures of an automobile engine. In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin (PAO) by volume, and 0.06% red dye by volume. A viscosity of the composition at 100 degrees-C ranges between substantially 7.2 and 7.6 centistokes (cSTs).

A bench-top dust collector has a front or intake side where air is directed by a cowling into a pre-filter and then a final filter that are held in a frame. A rear compartment holds an array of small high velocity fans that pull the air through the filters to a plenum in the rear compartment. The filtered air in the plenum is discharged through a grill in a downward and rearward direction. The unit is compact and configured to be about the size and shape of an attaché case.
