Performance Data Notes:

1.PD represents clean pressure drop in inches w.g. The recommended final pressure drop for all models is 2.0 inch w.g. Maximum final pressure drop is 3.2 inch w.g.

2.Operation down to zero air flow is satisfactory for all models

3.Efficiency is average and is based on ASHRAE Standard 52.1 test methods for 65, 85, 95 and 98% filters. Performance values stated may be averages typical of the products listed. Contact factory for actual performance test reports on specific products.

4.Performance tolerances conform to section 7.4 of ARI Standard 850.

5.Actual filter header is 5/16 inch under on height an width. Actual depth is 11-1/2 inch

Installation Consider tions

Superflow-V filters m y be installed in Flanders Type 9

Holding Frames, K-Trac Filter Framing Modules, Sureseal Side Access Housings or in similar existing hardware. Type 9 Holding Frames are riveted toget er to form a filter bank. K-Track Filter Framing Modules are especially suitable for medium to large built-up filter banks. Smaller systems and systems with minimum upstream access space are best served using Sureseal Side Access Housings.

Gasketed Headers are Standard

Superflow-V filters are furnished with a peripheral head- er on the air entering side and with foam gaskets on the “H” dimension for the 24 x 24 model and “W” dimension on the 12 x 24 and 20 x 24 models.
