Abstract: The present disclosure relates to portable forced air heaters and radiant heaters. Portable air forced air heaters include a blower, a blower housing, a burner disposed within the burner housing, a fuel tank in fluid communication with the burner, a fan pump and a battery connector. The battery connector of this disclosure allows for different batteries with different distinguishing features to be used.

Abstract: A fuel-fired heater can include a fuel tank; a housing assembly supported by the fuel tank, the housing assembly defining a chamber having an inlet and an air outlet; a fan located within the housing assembly; an air pump located within the housing assembly; an electric motor coupled to at least one of the fan and the air pump; a burner assembly located within the housing assembly, the burner assembly including a burner nozzle in fluid communication with the air pump and the fuel tank via a fuel line, and including an ignitor; and an electronic controller operating the electric motor and ignitor, the electronic controller including a proximity sensor oriented and arranged to sense an object located in front of the air outlet, wherein the electronic controller deactivates the electric motor when an object is sensed by the proximity sensor within a predetermined distance for a predetermined time period.

Abstract: A portable heater can include a housing including a base and an enclosure and a burner assembly disposed within the enclosure, the burner assembly including a heating surface, wherein the enclosure and the heating surface are rotatable, with respect to the base, between a first rotational position and a second rotational position. In some examples, the heating surface is a curved surface. In some examples, a tilt switch is provided that has a position that is independent of the rotational position of the enclosure. The portable heater can also include temperature control features for maintaining fuel tank temperature at an improved operating condition.

Abstract: A fan assembly designed for quick assembly and disassembly can include a housing, a fan and a motor disposed within the housing, a first guard located on a first side and a second guard located on a second side of the housing. The fan assembly can include a tensioner mechanism provided on an exterior of the housing to secure the first and the second guards to the housing. The fan assembly can be assembled by securing a plurality of struts to an interior side of a housing, mounting a fan and motor to the plurality of struts, inserting first and second guards within the housing proximate the inlet and outlet ends, and tensioning the first and second free ends of the housing to secure the first and second guards within the housing.

Abstract: A rotary vane pump including a housing, and a motor. The motor includes a shaft which is coupled to a rotor. The rotor defines a plurality of slots. A plurality of free moving vanes are disposed within the slots. In one example, the rotor is formed from a first material and the plurality of vanes are formed from the first material and impregnated with a second material. The first material can be a carbon material. The second material can be a resin material, an antimony material, a copper material, or a silver material.

Abstract: A forced air heater that includes two air moving devices for improved control of air and fuel mixture for combustion, and improved air flow the heater. In addition to better air flow, the heater includes an improved fuel system that utilizes a pump and delivery controls to accommodate reduced air flow while avoiding incomplete combustion and fume odors.
