Hon&Guan 100 mm Adjustable Air Vent for Interior Walls Ceiling, No Drilling

great product well made and finished, simple fins that fold in when you turn the unit clockwise mean that its simple to install into the opening and grips well once in place. Centre cap screws in and out to adjust air flow

Ordered and fast delivery (Prime). Good product works as should.

Does the job surprisingly well. Fitted perfectly in an existing hole. Just missing some insulation for when closed.

Easy to fit and looks decent. Just pushed into the old extractor vent hole and that's it. Easy to adjust how much ventilation as well

I got this to make a spray paint booth in my back bedroom. I liked the design and the fact that the inlet area was adjustable on a single screw thread. Its well made, tough and durable. For me it didn't need any fixings as it sort of screws into the opening with the three attached locking vanes expanding out behind it securing the vent to the opening. I am using it for a booth so the wall thickness is about 12mm. I do think it will work well on thicker walls but may need screws or bonding agent like No More Nails etc. For me, it was perfect for the job, looks great and pretty decent price.

Great product as expected snd good seal

These are ok quality wise but the diameter of the fitting is slightly too small to fit snuggly in 100mm duct so it leaves an air gap. Fine if you are using flexible duct though

These look good and don't appear to be dust collectors like some vent covers so should be easy to keep clean. Haven't fitted them yet but they seem to be easy to fit and use. My one niggle, there are no instructions with them, you need to contact the seller to access them on line which I was in the process of doing but we managed to work things out ourselves.

Ho sostituito le vecchie griglie di ventilazione in cucina, sono davvero carine e dal designer moderno. Per il prezzo pagato fanno la loro gran bella figura.

bon produit. evacuation de clim.

Excellent produit!
