NOTE: RPM Min (minimum) is determined when louvers are opened one inch

NOTE: Wind has a significant effect on exhaust fans. A 10 mph wind creates a 0.05” pressure gainst the fan. A 20 mph wind creates 0.20” pressure and 30 mph a 0.45” pressure. These pressures are in addition to the static pressure in the building. Wind blocks or hoods should be included in all designs where fans will be subjected to winds above 10 mph.
