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.

aluminized steel frame with fire-retardant
sealant.
2.3 Expanded metal aluminized steel faceguards
shall be installed on the air entering and air leav-
ing sides.
2.4 A 1/2” “T” strap shall be installed on the down-
stream side and 1/2” horizontal strap on the air
entering side.

3.1 Initial and final resistance shall not exceed the
scheduled values.
3.2 Media area shall equal that of the scheduled
high temperature filter.
3.3 The manufacturer shall guarantee performance
as outlined in section 7.4 of ARI Standard 800.
