Static Pressure will increase when replacing an air filter with a higher MERV rating when the area of the filter cannot be increased. This increase in static pressure will decrease the airflow when using a PSC indoor blower motor at the same speed. Installing Double Shaft Fan Motors Even though double shaft motors offer dual rotation CW (Clockwise) or CCW (Counterclockwise), it’s important to check the rotation from the lead end to make sure it matches the airflow direction.
