IAP Plug Fans can be fitted with four wheel designs to suit different performance needs. Airfoil (BPG) delivers smooth, efficient airflow at higher speeds with reduced horsepower. Forward Curved (FPG) moves large volumes of air quietly at low speeds and handles elevated temperatures well. Radial (OPG) provides strong structural durability, ideal for moderate pressures and wear liners with excellent temperature capacity. Vax (XPG) uses aerodynamic propellers with guide vanes for maximum efficiency, moving high air volumes at moderate pressures with greater capability than standard axial fans.

Item Details

A versatile and compact fan design solution for circulating air and maintaining a constant temperature gradient. IAP Plug Fans are a durable, efficient and economic choice for a wide range of industrial applications.

• Capacities to 300,000 ACFM with static pressures to 20 in. wg.
• A space saving solution for horizontal or vertical mounting.
• Elevated temperature construction from standard 300°F to 1800°F with upgrade packages for isolation and alloys of construction.

Most applications utilize the system plenum as the fan housing which reduces space requirements and ductwork connections, however, fan housings are available as an option to any IAP plug fan.

Adjustable motor base, removable guards and readily accessible bearings reduce maintenance time. Motor and drive assembly are mounted to a formed steel plate plug panel with flanges and cross-frame bracing for strength and flatness. Plug panel is pre-drilled and all units are factory assembled and balanced ready to “plug” into your supply, exhaust or recirculation system. Unit shown to the left is a floor mount option with round plug and detachable housing.

Configuration Examples

Above left and right: 84” diameter XPG fan with insulated plug for a curing furnace.

Motor and drive assembly are mounted to a formed steel plate plug panel with fl anges and cross-frame bracing for strength and fl atness. Plug panel is pre-drilled and all units are factory assembled and balanced ready to “plug” into your supply, exhaust or recirculation system.

Inlet cones for type BPG and FPG plug fans ship loose for mounting to the inside of the plenum/system wall or can be integrally mounted to the plug panel as an option.
