Hon&Guan 4 Inch Adjustable Air Vent Covers 100mm Ceiling Vent Indoor Vent Covers for Walls Closeable Round Ventilation Cover for Caravans, Cooling and Ventilation Systems

Used to replace extractor front. Good fit and adjustable to allow more airflow

Good adjustable Air Vent cover, the only problem I had ( which I didnt solve) was how you seperated the parts in order to fix to the ceiling with the screws provided, I found it impossible to seperate , so mine is only held by the tesion onto the ducting. The instructions dont indicate or mention the seperation

Easy to fit, just fold the fins in and push it in. If you twist it as you put it in it grips the plasterboard a bit more but might want some dabs of silicone to hold it a bit better. Diffuses the air to help reduce noise and can adjust the opening by twisting the middle circle. I agree with others that it doesn't look pure white. I think because it's not glossy compared to most white surfaces in a bathroom.

Bought for two rooms off one inline fan, adjustable vents help to balance extraction rate from different length ducting. Nice fit, easy on the eye. Happy customer.

I got this to replace a vent cover that looked old and yellowed and because it had louvres it collected dust and always looked grubby. This looks good (not brilliant white, more chalk white), is easy to fit, and the fins allow you to rotate it in and they pop out in the roof cavity holding the vent firmly in place without the need to use screws. You can unscrew the central part of the vent to vary the air gap. Great value for money, decent quality. I’m happy.

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

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.

Arrived swiftly and is exactly what I needed. Good quality and easy to fit.

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.
