Sonic SFH2 Exhaust Fans
Sonic heavy duty industrial wall mounted exhaust fans are well suited for warehousing, kitchen or production areas ventilation.
With its unique motor design, clockwise or anti-clockwise rotation is configurable by user with just a simple re-wiring at the back of the motor. Thus, allowing the exhaust fan to extract or blow-in air as desired.
The effectiveness of ventilation is greatly enhanced with correct placement of the exhaust fan as shown. The required air flow rate (CFM) can be calculated by using the formula below;
CFM = (ACH / 60) x L x W x H, where
ACH: No. of Air Change per Hour. ACH for normal typical room is 5 or 6.
L, W, H: Length, Width, Height of room in ft.
