HVACQuick IFWB Series W-Bank Insulated High Flow Inline Filter Boxes

HVACQuick IFWB Series W-Bank Insulated High Flow Inline Filter Boxes

HVACQuick's IFWB series of inline filter boxes are a great solution for any application requiring high MERV filtration and CFM with a low pressure drop. Designed to fit 10 to 20" ducts. The filter access door attaches securely with latches, and opens easily for filter replacement. The boxes are constructed from 0.040 double walled aluminum with 1" of R4.3 fiberglass on 4 sides of body (insulation and double walled on 4 sides, not on collar connections).

The IFWB boxes use 24x24" replaceable filters in 2" thickness (23.38 x 23.38 x 1.75" actual filter size). 4 filters are required per box.  One MERV-13 filter set is included with purchase.

#1 Q:   What is the pressure drop through a unit with 425 CFM and 1150 CFM? We do not need the pre-filter, just the H13 HEPA?
A:   We do not have test number available yet for these units. It would depend on the duct connection size. You do not need a pre-filter. Note these are MERV-13 filters, not HEPA.
