Notes:

1.PD represents clean pressure drop in inchw.g. The recommended final pressure drop is 2.5 inch w.g.

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

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

4.Performance values stated may be averages typical of the products listed. Conta t fa tory for actual performance test reports on specific products.
