  • Air filter cleaning device
    Patent number: 6588057
    Abstract: An air filter cleaning device has en elongate, readily gripable handle having a through bore and a connector at one end for coupling to an air supply hose, and a rotary head is rotatably mounted on the other end of the handle. The rotary head has an internal air distribution chamber with small outlet openings in its outer peripheral wall for spraying air from the chamber. Rotor outlet passageways in the peripheral wall are arranged at an angle to cause the head to spin in a turbine-like fashion when air flow is directed from the chamber and out through the passageways. The rotating head sprays air outwardly across the surface of an air filter unit to dislodge dirt from filter paper in a filter unit.

  • Air filter cleaning apparatus
    Patent number: 5182832
    Abstract: An inlet tube has a connector at one end for coupling to an air supply hose, and a rotary head is rotatably mounted on the other end of the inlet tube. The rotary head has an internal air distribution chamber connected to the inlet tube and small outlet openings in its outer peripheral wall for spraying air from the chamber towards an air filter unit. Rotor or spin outlet passageways in the peripheral wall are arranged at an angle to cause the head to spin in a turbine-like fashion when air flow is directed from the chamber and out through the passageways. The rotating head sprays air outwardly across the surface of an air filter unit to dislodge dirt from filter paper in a filter unit.
