Direct Drive Fan Selection
Three propeller and drive frame combination levels are available with either
a L or H type propeller. 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
Three propeller drive frame construction levels are available with either a
L or H type propeller. The application requirements for sound and static
pressure determine propeller type. Propellers are available in fabricated
steel, fabricated aluminum or cast aluminum.
Level 1 Level 2
C in model name indicates cast aluminum blades and hub.

• 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

• These propellers typically run
at higher RPMs and generate
