PMAX3 is engineered for applications with restricted space that require high static pressure. The narrow-depth fan has a new blade root design as well as a minimum axial deflection. It is suited for stationary applications such as radiators and oil coolers, generators and mobile compressors. Offered in diameters from 17.5 to 25”, the fans have an axial depth of 3 to 4.5”. The 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.
