Notes:
1. PD represents clean pressure drop in inches w.g. The recommended final pressure drop is 2.5 inch w.g.
2. Operation down to zero velocity is satisfactory for all models.
3. Efficiencies are average and are based on ASHRAE Standard 52.1 and 52.2 dust spot test methods.
Performance values stated may be averages typical of the products listed. Contact factory for actual perform-
ance test reports on specific products.
4. Perfmormance values shown in this publication may be averages or estimates intended to generally represent
product styles. Always contact factory for latest actual test data on specific Flanders Precisionaire models.
