ABSTRACT:
An electrical heater is disclosed capable of producing dry, clean, heated compressed air having a housing with spaced apart end compartments and a heating unit mounted between the compartments. Regulated compressed air is caused to circulate through a plurality of chambers formed by tubes enclosing the heating unit where moisture is removed before it is passed to a filtered outlet. The moisture is collected in one of the compartments and automatically drained therefrom when the heater is not in use. A temperature responsive sensing element in the path of the circulating compressed air controls the degree of energization of the heating unit.
