Backward Curve Fans for Custom Pneumatic System in Ontario
 Backward Curve Exhaust Fan
Design
We manufacture Backward Curve fans for a custom pneumatic
system in Ontario. Our Backward Curve exhaust fan design meets
the highest standards.
- 4000 to 150 000 cfm
- 18” to 98” wheel diameter
- Up to 30” of water
The MacDonald Steel Backward
Curve (BC) fan casing is manufactured from reinforced heavy
plate construction.
The BC fan is a high efficiency exhauster, using 25% less
power than conventional exhauster designs. The BC's efficiency
is derived mainly from its unique impeller. Its dimensions
and backward curved blades have been purposefully designed
to operate in the flow and pressure ranges required by dust
collection systems.
The BC fan remains efficient over a wide range, making it
insensitive to most system fluctuations or modifications.
These combined factors often result in a smaller BC fan to
do the same job.
Another advantage is the BC's low sound levels. The casing
and optional inlet box has been tuned to reduce sound levels
by at least 29 dB versus other exhausters delivering the same
performance.
