How
panel structure affects fan life
The panel structure of a wall
fan or PRV directly impacts the overall rigidity of the unit. This
in turn affects its propensity to vibrate. A rigid welded ten gauge
angle frame with minimum ten gauge motor brackets and shaft supports
provides greater rigidity and longer life than tubular frames or bolted
angle frames.
Welded heavy
angle construction makes the difference
In addition, panel structure is often subjected
to corrosive environments that quickly take their toll on lighter
gauge material. This can lead to the early retirement of the unit.
American Coolair uses welded heavy angle construction for all panel
elements.
