How high does it sit off the floor or away from the wall once it’s scewed in?

Asked by Jeremy February 20, 2019
3
Answers

Height off the floor depends on the height of the range hood or microwave. It fits flush to any wall depending on the finish and contours and position to the hole. I put mine on a park model trailer with corrugated siding and used a good caulking to seal gaps. It shouldn't be away from the wall as the vent can be shortened to as needed

Does this wall vent have an insect screen?

It has a flap that closes when you turn the fan off..

How much cfm required to open damper?

Asked by gebhere April 14, 2018
4
Answers

Not sure what the minimum is but I have 300 cfm and no problem. It opened guite aggressively and I would guess it would take a lot less cfm's to open.

what type of sealant should be used between outside flange and house surface?

Asked by doug March 13, 2018

Answers

A good quality caulking that doesn't shrink is recommended

This vent worked well for venting through a standard brick exterior wall with a Proline range hood. At just over 3 inches tall, it is ALMOST the same size as my brick and mortar so I only had to do minimal grinding of the bricks above and below the opening. I also like that the ducting attached to this vent was the perfect length (approx 9 inches) so that it reached almost all the way thru the wall to the little flange on the back of the range hood. My only complaints are that there is no insect screen and the spring is not designed well.

The wall vent was easy to install and works great! I will add a piece of metal screen under the flap to keep the critters from making any sort of home for themselves.

Way stronger then the thin aluminum style which cost more then this one. I needed a 5 inch duct so cut off 4 inches was easy to cut with snips. Slides over easy the connecting duct work and the flapper has a strip at bottom made of felt for quiet closing. TIP: if flapper stays open all the time from outside wind..just add two small pieces of magnets at each bottom ends of flapper ( buy at dollar store one of those monthly charts on the back is a 4 inch magnet that is like paper thin and can be cut to any size ). GOOD BUY

Perfect for the situation. Installed for a kitchen remodel where there was previously no external exhaust. Had to cut a hole thru the stucco siding then this slid right in with some silicone to seal it up. The insane inspection wanted some foil tape on the one seam but that was a quick fix. Looks good and paintable.

So poorly constructed that the vent was unusable. Misalignment was so bad that three of the four nail holes were either partially or completely covered with metal. Gaps in metal seams, warped exhaust flange and almost no contact with insulating foam. Foam strip totally inadequate for proper sealing even if the unit had been constructed properly. The only thing good to say about this unit is that it has a 9 inch tail piece. How they can describe it as suitable for a 10 inch wall is a mystery. In addition, numerous scratches in the paint. How can a boxed exhaust be packed with so many defects? No quality control whatsoever and it will cost me an additional hour of labor to return to the store.

Great microwave vent
Works just fine. I had to reduce length of sheet metal channel duct, leaving 1, out of 2 spot welds at base of channel. Now I wish I had a pop-rivet gun to secure sheet metal shape facing the micro. After one month, exhaust vent works just fine, I'm pleased.
