Construction
Die Formed Cabinet - Heavy 18 gauge steel, phosphate undercoated for corrosion resistance and finished in almond polyester powder coat.
Louvers — Individually adjustable louvers direct air flow up or down as needed.
Fintube Heating Elements have corrosion resistant steel fins that are furnace brazed to the tubular element to assure long life and superior heat transfer.
Fan Motor —  Totally enclosed fan motor is rated for continuous duty with built-in thermal cutout and operates on same voltage as the heating circuit.
Dynamically Balanced Fan is attached with rubber vibration insulators for smooth, quiet operation. Blade pitch is carefully selected so that the volume of air moved results in the optimum discharge air temperature.
