CANADA BLOWER PLUG FANS

Plug Fans are used in applications where the system plenum acts as the fan housing, combine versatility with compact design to reduce overall system costs. This is achieved while maintaining operating efficiencies nearly equal to conventional housed fan equipment. The Plug Fan eliminates the need for connecting ductwork; its mounting panel permits assembled-unit installation to any well-supported plenum wall. These fans, which are literally plugged into a system, are a natural for supply, exhaust, or recirculating-air applications.

Plug fan designs features a non-overloading horsepower curve: brake horsepower reaches a peak and then decreases as flow increases… allows calculation of the maximum brake horsepower at a given fan speed so a motor can be selected that will not overload if system pressure changes.

The airfoil-blade fan wheel design is the most efficient and quiet selection for clean, dry airstreams. A flat, backwardly inclined fan blade is best-suited for the efficient movement of moist or mildly contaminated airstreams. The BI fan wheel’s single-thickness blades handle airstreams not suited to hollow airfoil shapes.

Plug fan housings are designed to maximize performance with Airfoil, BI, or Backward Curved wheels and to direct the airflow to a specific location in the system. Plug fan housings are continuously welded and furnished with mounting studs on inlet side, large cutouts on both sides for wheel removal, and flat surface on drive side for easy installation. Housings are rotatable and available in clockwise or counterclockwise design.

Plug Fans are an integral part of the ovens and dryers in which they are applied. Plug fans handling hot airstreams must be kept in operation after system shutdown until the airstream cools below 200°F to prevent damage to the fan. The plug fan wheel or shaft might otherwise distort due to “heat-soaking”. The shaft cooler is only effective while rotating. Burners should be located so that the air is thoroughly mixed before entering the fan inlet. Improper placement could cause hot spots on the fan wheel which exceed maximum design temperatures.
