Installation guide

The effectiveness of ventilation is greatly dependent on the air path as shown below:
Air flow path

Air Flow Calculation

The formula below can be used to determine the CFM required for the room:

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.
