From the Manufacturer
What makes the Air King high performance bath fan series unique is the UL listed molded high impact plastic housing that provides multiple benefits. "Traditional" bath fan housings are fabricated from steel which involves bending and welding. This is a more expensive process and over the life of the fan welds can break, causing the fan to operate much louder or even with a rattling sound. Metal housings reverberate and echo noise. Because the Air King high performance bath fan series is in an all plastic housing, there are no welds to break and the plastic is a natural sound absorbent material. If you live anywhere near salt water, or the unit will be used in high moisture areas, this fan is an almost must. The UL listed molded high impact plastic housing will not rust, giving the unit a longer life. The high performance exhaust fan series features a unique snap-in installation system. The 4-Inch plastic duct collar with back draft damper insures quiet operation and prevents drafts from entering the room. Exhaust capacity for rooms of approximately 90 to 115 square feet. Housing size: 9-1/8 inch wide by 8 1/2 inch deep by 4 3/4 inch high. Meets ASHRAE 62.2 specifications for Local Exhaust. Quality Air King products are always the right choice!
