Multi-Wing Introduces PMAX3(TM) Narrow-depth Axial Fan

BURTON, Ohio—Multi-Wing introduces PMAX3™, its latest precision airflow fan. PMAX3 narrow-depth axial fan is engineered for applications with restricted space that require high static pressure. Featuring a new blade root design, PMAX3 is Multi-Wing’s strongest profile. This narrow-depth fan has a minimum axial deflection and is ideal for many stationary applications and off-road equipment. They include radiators and oil coolers, generators, mobile compressors, small- to medium-size tractors, rollers, compact wheel loaders, excavators and other off-road equipment. 

Offered in diameters from 17.5 to 25 inches (445 to 635 mm), PMAX3 fans have an axial depth of 3 to 4.5 inches (77 to 114 mm). These modular fans are available with 3-, 6- or 9-blade configurations and have pitch angles from 20° to 47.5° in 2.5° increments. Blades are constructed of glass-reinforced polyamide (PAG), which has an operating temperature from -40° to 240°F (-40° to 115°C). The hub is constructed of pressure-die-cast aluminum alloy.

“PMAX3 exceeds requirements for restricted spaces in equipment and engine compartments while reducing operating noise. As emissions regulations continue to evolve, customers need a greater range of modular-fan solutions,” says Jim Crowley, president of Multi-Wing America. “The flexibility of Multi-Wing’s broad line of modular-fan products, combined with dedicated engineering support, prototyping and advanced manufacturing, allows us to deliver the right fan, quickly.”  

A 15.75 inch (400 mm) diameter PMAX3 has tip speeds of up to 426.51 feet per second (130 meters per second). The maximum-diameter PMAX3 fan is capable of operating at 3800 rpm. This narrow-depth, high-static pressure fan is compatible with MAHLE T13, T35 and competitive fan clutches.
