PM plenum fans are an ideal cost-effective solution for performances required in Class I and the majority of Class II ranges. Fan selection is simplified with one fan design for belt drive and one design for direct drive. Both designs feature the motor mounted directly to the fan to reduce the fan s footprint. The PM utilizes a bolt-together framework that is either galvanized or coated steel and features a high-efficiency, low sound 12-bladed aluminum airfoil wheel, making it the perfect selection for light and medium duty applications. PH plenum fans are designed and engineered for superior performance and reliability for industrial applications. Model PH features welded construction and a powder coated framework. Quiet and efficient operation is achieved through the same 12-bladed airfoil aluminum wheel utilized on the model PM, thereby offering the highest performance capabilities. This wheel design saves energy and improves the overall sound quality by reducing low frequency tones which are difficult to attenuate. In addition to sharing the same high-efficiency and low sound wheel design as the PM, the PH also features longer life L 10 80,000 hour bearings, and a wider range of mounting options and accessories. vailable up to Class III.

4 Standard Construction Drive Frame ll plenum fans feature a laser cut and formed framework. Model PM utilizes galvanized steel construction, while the PH features a fully welded design with Permatector, an electrostatically applied polyester urethane powder coat finish. Fan Shaft Shafting through 2 inches (50.8 mm) diameter is ISI (merican Iron & Steel Institute) 1018 steel. Larger shafts are ISI 1045 steel. ll shafts are turned, ground, polished and sized so the first critical speed is 150% of the maximum operating speed for increased bearing life and decreased vibration. Premium Quality Bearings Belt drive plenum fans are supplied with air handling quality bearings, which are 100% inspected to be within tolerance for swivel torque, noise levels, and bore size specifications. Other PH bearing design features include concentric mounting collars, which provide superior grip force between the collar and the fan shaft, and zerk fittings for lubrication. Single Pressure Tap single pressure tap comes standard with the PH/PM on the inlet cone venturi for easy field airflow measurements. 12-Bladed Wheels Traditional plenum centrifugal wheels utilize 9-blade wheel designs. Both the PH and PM plenums feature the same high efficiency and low sound 12-bladed airfoil design. The aluminum wheel reduces start-up torque requirements and shaft loading during operation. Blades for sizes are constructed of 6063-T5 aluminum extrusions, while sizes utilize precision laser cut and die formed 5052 aluminum blades to improve efficiency and reduce vibration. ll wheels are balanced to grade G6.3 per NSI S2.19.
