Low Profile: The height of all Q Series models is 12-5/8".
Standard Ceiling Size: All 2' x 4' models are designed to fit a nominal 2' x 4' ceiling grid with a 22.5" x 46.5" standard opening.
Air Flow: Airflow ranges from 500 to 750 CFM for a 2' x 4' unit and 250 to 400 CFM for a 2' x 2' unit. At 90 FPM, CFM is nominal 632 on a 2' x 4' and 300 on a 2' x 2' unit respectively.
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. Field conditions, voltage and method of testing could produce different results.
