ABSTRACT:
An air dispersing head for an air heater which includes a generally cylindrically-shaped cap having an inset or recess on one side and fitted with a nozzle base and nozzle in the recess, with the nozzle communicating with the interior of the cap. The nozzle is fitted with a hose of selected length and the cap is further provided with a primary air duct and a plurality of secondary air ducts in a curved rear face oppositely disposed from the nozzle. Air is forced through the bottom of the air heater by an internally located fan, and is heated by coils, channelled through the air dispersing head and ejected from the hose. Unheated, ambient air enters the air dispersing head through the primary and secondary air ducts and mixes with the heated air to control the temperature of the air ejected from the end of the hose.
