SP-KFA1000 ROTOR WITH BLADES, DURAHEAT, DYNA-GLO

The SP-KFA1000 1/2 inch Rotor Kit is designed to fit the several different brands of portable kerosene heaters including the DuraHeat models DFA45, DFA65, DFA70, DFA120, DGFA125, DFA170 as well as many models of Dyna-Glo and Dyna-Pro portable kerosene heaters.

This SP-KFA1000 Rotor kit is the heater's air pump assembly and consists of a rotor, rotor insert and four carbon blades rotating inside a 1/2 inch metal pump ring body.

The SP-KFA1000 Rotor Kit Kit consist of the following parts:
1 288-3100-50 Rotor 1/2 Thick, Carbon
4 284-3100-60 Carbon Blades 1/2 x 1/2
1 288-3100-70 Insert, Plastic

The SP-KFA1000 Rotor is driven directly by the motor and is attached to the motor shaft by means of a plastic insert. As the motor rotates, the carbon blades travel outward rubbing against the inside surface of the steel pump body.

The rotor's position inside the pump body is such that it is not concentric with the pump body and a .003/.004 of an inch gap is set at the uppermost quadrant.

As the motor rotates, the air between the blades is compressed and routed to the nozzle through the air line.

The carbon rotor blades will wear out after time and cause the output filter to fill with carbon particles. Replacement of the output filter and carbon blades should be done on a regular basis.
