Mfg. Code: 302200
Description: 2'×4' GS Style HEPA Filter, 99.99% eff. @ 0.3 micron

GS Style Filter Data: 90 FPM average face velocity @ initial 0.47 w.g. and 99.99% efficient @ 0.3µm. An anodized aluminum frame holds the 53mm media which is protected by a diamond pattern white epoxy coated steel grille. Final filters are room side replaceable.
Access Port: This port is located in the center of the filter element face and is used for introducing an upstream challenge or measuring static pressure.
Air Flow: Airflow ranges from 340 to 640 CFM for a 2'×4' unit and 220 to 340 CFM for a 2'×2' unit. At 90 FPM, CFM is nominal 510 on a 2'×4' and 220 on a 2'×2' unit respectively.
Standard Ceiling Size: All 2'×4' models are designed to fit a nominal 2'×4' ceiling grid with a 22.5" x 46.5" standard opening.
Sound Level: At average face velocity of 90 FPM measured 30" from face of filter, sound level is approximately 50-52 dba with less than 45 dba ambient sound level. The different conditions will affect the test results.
