High-Efficiency, High-Pressure PMAX7 Fan

March 28, 2023



The PMAX7 axial fan is engineered to deliver increased airflow for power generators, harvesters, and large construction equipment. Featuring fewer blades, PMAX7 has a lower profile to fit into tight spaces. Blades have an optimized backswept design for reduced noise and more efficiency in most applications.


Offered in diameters from 47 to 63 in. (1,200 to 1,600 mm), these modular fans are available with 5 and 7-blade configurations with 26, 31, and 36-deg. pitch angle options. Blades are constructed of polyamide, reinforced with glass fiber, which has an operating temperature from -76 to 221°F (-60 to 100°C). The hub is constructed of steel.


PMAX7 fans have tip speeds up to 351 ft/s (107 m/s). PMAX7 fans of 63-in. (1,600 mm) diameter are capable of operating at 1,280 rpm. This high-static pressure fan is compatible with Cojali EV350 fan clutches.
