F2 B
Vertical Wall Mount

Low Silhouette Vertical Basic

Part Number: F2-B

The Vertical Low-Silhouette Basic (F2-B) is a low-static (up to .25 ESP) top vertical discharge fan coil with a blow-through design. The F2-B fan coil 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 cabinet is insulated with ½-inch thick, over three pound density, neoprene-coated fiberglass. The F2-B has a top-discharge duct collar. The 14½-inch high F2-B is designed for under-the-window furred-in applications with a field-fabricated, custom enclosure. This model has no exterior cabinet.

Cooling Capacity

F2 Series vertical fan coils have been rated in accordance with AHRI Standard 440-2005 for room fan-coils air-conditioners and are certified by AHRI to meet the following product performance ratings:
