Electric Motors and Specialties offers a full line of single piece fan blades to be used with the unit bearing fan motors. The offerings include aluminum and galvanized steel four and five petal designs in diameters of 6″ to 14″. All are of a material thickness and mass to promote quiet and efficient operation and to minumize vibration.
Where practical, EM&S sales engineers recommend threaded shaft unit bearing mount fans because they save the cost of fan hubbing, guarantee positive fan position in the oriface, and they virtually eliminate any chance of the fan coming loose from the shaft.
Although most blade models are available with pitches as low as 10 degrees and limited to a high pitch of 37 degrees, it is important to know that it is normally advisable to match the motor power to the fan so that the optimum airflow is attained with 20 to 32 degree pitched fans. Experience demonstates that this often delivers the most airflow with the least horsepower applied.
