Wall Exhaust Fans, also known as industrial wall fans, are commonly used by industrial buildings to create air change by directing stale and hot air out of the building. By creating this air change, the area is kept fresh as new air will replace the contamination and heat that was exhausted out. Typically used to remove heat, smoke, contamination, or other odours that may be created in industrial operations.

Features & Benefits
3 Different Sizes
Always install the wall fans at the highest point
If wall fans are selected to exhaust out the air from inside, always install the wall fans at the highest point on the wall. The reason is that the hot air stays at the top and if the wall fans are installed too low, the hot air will be pulled down to lower area.
Prevent air short-circuiting
Where the building has louvered wall all round, the louvered walls close to the wall exhaust fans should be covered or sealed so that outside air is not quickly sucked in and sent out. If this happens, the large part of the building will have no air flow. We call this air re-circulation or air short-circuiting.
