Performance shown is for installation type A: free inlet, free outlet. Performance ratings include the effects of birdscreens in the airstream. Speed (RPM) shown is nominal and performance shown is based on actual speed of test. The sound ratings shown are loudness values in fan sones at 5-ft. (1.5M) in a hemispherical free field calculated per AMCA Standard 301. Values shown for ventilators listed are for installation type A: free inlet fan sone levels.

where steady exhaust is required • Roof or wall mount applications • Features spun aluminum housing construction, steel support braces, backward inclined aluminum wheel, externally cooled motor compartment, birdscreen, junction box, welded curb corners and maximum operating inlet temperatures up to 170°F • Open drip proof motors, single-phase, 115V, except X90-891 , X90-894 , X90-895 are 115/230V
