One-Piece Molded Fans
Designed for equipment with compact engine compartments, one-piece molded fans have blades constructed of glass-reinforced polyamide (PAG) with an operating temperature range from -40 to 230°F (-40 to 110°C). The fans are compatible with bimetal or E-visco fan clutches. In addition to its existing O-PMAX2, the company added two models: O-PMAX3, with a diameter range from 17 to 23.6” (432 to 600 mm), and O-PMAX4, with a diameter range from 23.6 to 30” (600 to 762 mm). Features include a fixed-pitch angle fan. The largest-diameter O-PMAX3 has a maximum axial depth of 3.74” (95 mm) and operating speed up to 3450 rpm. It is available with a 0.86” (22-mm) pilot. The-largest diameter O-PMAX4 has operating speeds up to 2426 rpm. A cup-shaped mounting plate version is available to keep total width as minimal as possible.
