Broan 646 Reviews

Rated 5 out of 5 by from Another first timer Easy company to shop from, delivery came quickly. Product dimensions shown in sketch were accurate. The thin gauge sheet metal duct on the back could be easily snapped on or off. There was a bird guard behind the louvers to keep out birds/squirrels. I didn't like the white color so I spray painted it to match my house siding.

Rated 4 out of 5 by from Should help keep insects out We had a problem with wasps or hornets coming in through our bathroom fan ducts. These flappers closed by gravity should help eliminate that problem. The 6+" long (nice!) thin metal fitting attached to the plastic exterior has a tendency to pull out of the plastic face when it is being slipped into the long exhaust pipe. That can make it awkward when working in a cramped attic, having to pull the inside pipe back out of the exhaust pipe, re-align both, then couple the thin inside metal fitting to the exterior plastic face. Once installed, the exterior has a clean appearance, with the fan's air movement easily opening the flaps. How well those flaps work through cold Chicago suburb winters remains to be seen.

Rated 5 out of 5 by from First time with Vent Dir My total experience was fantastic. The ordering was easy and the product was delivered early. I would highly recommend this company and will use them again.

  • What are the advantages/disadvantages between the louvered wall cap and the hooded wall cap (such as broan 843BL). Does the hooded wall cap seal better to avoid backdrafts?

    A. The difference is just the exterior appearance. The hooded cap will protect from back drafts better and also it reduces outside noise coming back through the ducting. The louvered units tend to flap and make noise in windy conditions.
