High-Performance Horizontal Ceiling Mount

High Performance Horizontal Rear Return-Air Plenum

Part Number: H3-R

The High-Performance Horizontal Rear Return-Air Plenum (H3-R) is a high-static (up to .50 ESP) fan coil that comes with a coil, blower/motor assembly with quick-connect plug and a galvanized steel, powder-coated epoxy drain pan covered with ⅛-inch thick insulation. The galvanized steel plenum is insulated with ½-inch thick, over three-pound density, neoprene-coated fiberglass. The plenum conceals the fan and motor assembly that is easily accessed for service by removing the bottom panel. This unit is easily mounted above ceilings, in closets, and in hallways.
