Filtration Group Air Handler 4PY72 Titan FP V-Bank Air Filter 24 x 24 x 12 in, MERV 14, 2000 SCFM

This is an Air Handler brand 4PY72 titanFP air filter, 24 x 24 x 12 inches nominal, rated MERV 14 under ASHRAE Standard 52.2. Air Handler is a filter brand sold through Grainger, and the label states the filter was manufactured for Dayton Electric Mfg. Co. of Niles, Illinois. The record lists Filtration Group as the manufacturer and Titan FP as the model.

A 12 inch deep, 24 x 24 inch filter is the standard final or secondary filter size for commercial air handling units, where it slides into a filter rack or holding frame downstream of prefilters. The label rates this filter for 2000 SCFM at a face velocity of 500 feet per minute with an initial resistance of 0.52 inches of water gauge.

MERV 14 means the filter captures 75 to under 85 percent of particles from 0.3 to 1.0 micron and at least 90 percent of particles from 1.0 to 10 microns in the standard test. That level is commonly specified for hospitals, laboratories, office buildings and manufacturing spaces that need cleaner supply air. The filter is UL Classified Class 2 for flammability. HVAC mechanics and facility maintenance teams stock this size for scheduled filter changes.
