The Horizontal Basic Belt Drive Air Handler (HWG) draw-through designs are available for indoor applications and are equipped with blowers that can handle high static applications. The HWG is housed in heavy-gauge galvanized cabinet (or painted casing) and insulated with ½-inch thick, over three pound, neoprene-coated fiberglass. The HWG comes with a ½-inch OD copper tube coil, forward-curved, dynamically balanced belt-driven blowers, motor, and a galvanized steel, powder-coated epoxy drain pan insulated with ⅛-inch thick insulation. A flat filter section, with a two-inch, 30% pleated efficiency filter is included. Access doors are located on both sides of the unit for easy maintenance. Supply and return-air openings have a one-inch duct collar.
