Model Comparison
Direct Drive Fan Selection
Three propeller and drive frame combinations are available. Models SE1 and SS1 are designed for smaller
size applications where lower volumes and static pressures are found. Models SE2, SS2, SCE3 and SCS3
are designed and constructed for applications with higher volumes and static pressures.

Belt Drive Fan Selection Propeller Types
Three propeller drive frame construction levels and two blade designs are available. The application
requirements for sound and static pressure determine propeller type. Propellers are available in fabricated
steel, fabricated aluminum or cast aluminum.

Blade Designs
L Propeller:
Swept, steeply pitched blade design. These propellers typically run
at lower RPMs and generate low sound levels making them the best selection for
sound critical applications or applications that require the best combination of
both air and sound performance. Typically used when the static pressure is 0.5 in.
wg (13 mm) or less.

wg (13 mm) or less.
H Propeller:
Straight, moderately pitched blade. It is designed for applications
where static pressures are above 0.5 in. wg (13 mm). These propellers typically run
at higher RPMs and generate slightly higher sound levels than the “L” propellers.
