Reznor model RA is a fan-type unit heater with a propeller fan designed for air delivery to open areas.  Model RA units feature a low-stress heat exchanger and a heavy gauge combustion chamber with large, easily accessible service panels.  The air atomizing burner provides excellent flame retention.  Air for atomization of the oil is provided by an onboard piston-type compressor.
