Kair Bull-Nose External Vent 150mm - 6 inch Rear Spigot Stainless Steel Grille with Louvres, Fly Screen and Drip Deflector

Sturdy, good colourthe drain piece is a good thought.The rubber placer provides amazing seal.

I had been struggling with back draughts coming in through my kitchen extractor. I don’t know if it was worse because I have a 6” extractor hose and exit compared to most domestic ones being 4”. I tried a standard slatted type of cover and the wind just blows straight through, I tried the ones where the slats open when in use and fall closed when not in use but the rattling of the slats in the wind absolutely did my head in. This on the other hand may look slightly industrial on the side of your house, but I am good with that because it does a great job of preventing the wind coming back through it. Yes it’s more expensive than the plastic ones, but in my opinion definitely worth it. I presume that if you have a prevailing wind usually coming from the same direction, you could rotate it when mounting and direct it away from the wind, which would help even more, but mine is mounted in a location where the wind swirls with wall, 6ft fence, gate etc, so it just faces down and has made a huge difference. It also has a fly screen built in too which I also think helps cut down on the wind (definitely wind noise), but certainly helps prevent flies, wasps, bees etc climbing in which would be the main purpose.

Easily installed and looks great

Bought this to replace another plastic cowl vent for our ac. Easy to fit and looks great. All in all very happy with it

The fine wire mesh at the outlet barely restricts airflow compared with the plastic mesh of the unit it replaced.

Used this with the kitchen extractor ducting, really improved the external aesthetic of the house. Easy to install and well made.

Looks good better than a plastic one

Excelent product all as described arrived on time, spigot fits inside a 100mm internal dia pipe. Only problem is the fixing screws are too near the edge which is a problem with most cowls/grills.However It does look good.
