Abstract:
This is a compact apparatus for generating a hot airflow to be utilized for all those functions where a hot airflow is suggested or required as, for example, in prep stations, spray booths and mix rooms. An outer air duct, that has one of its end closed, contains a second, smaller air duct that houses a fan, powered by a motor, and a gas burner. Cool air enters the outer air duct, passes through the warm hollow space between said two air ducts, goes through said burner located inside the inner duct, and hot air exits from the inner air duct. It is energy efficient, simple to operate, cost effective, and space effective.
