1.PD represents clean pressure drop in inches w.g. The recommended final pressure drop for all models is 1.5 inches w.g.

2.Operation down to zero airflow is satisfactory for all models.

3.Consult factory before operating at these velocities.

4.Effici ncy av rage is based on ASHRAE Standard 52.1 test methods. Performance values stat d may be av rages typical of the products listed. Contact factory for actual perform- ance t st r ports on specific products.

5.Performance tolerances conform to Section 7.4 of ARI Standard 850

6.Actual face size is 5/8” under on height and width. Actual filter depth is 5-7/8” or 11-1/2”
