Good product at a great price

I purchased this to replace our attic fan that had stopped working. It was easy to install and works great.

Excellent product and unbeatable drillspot value

Wednesday, September 02, 2009

This is a replacement for a Broan 350F installed almost 15 years ago on a roof/attic not far from the ocean in Hawaii. When the motor failed recently, it seemed that buying an entire ventilator and using only the motor/blade/thermostat/wiring box assembly (just 1 bolt on each of three mounting struts) was the most efficient and economical solution. Exposure to salty airflow over the years caused noticeable rust on/in the thermostat, motor/shaft and mounting struts. I had painted the fan blade and wire grille to prevent rust when first installed and was glad I did. Also spray-painted the non-metallic hood to match the roof shingles and the paint has held perfectly, with only a single touchup needed for fading since installation. had a competative starting price, only a couple of dollars more than other online sources and much less than most, but with the free shipping offer (which, surprisingly included Hawaii) it is a hands-down price winner. Hope I can get another of these from if/when the other original ventilator decides to "die". Order was processed very quickly and shipment arrived faster than I expected. THANK YOU DRILLSPOT.COM!

Very reliable, straightforward installation. Non-metallic cover (hood — paintable).

Some bare metal parts should be painted to protect against corrosion in salt air environment installations.
