HG Power 5 Inch Air Vent Covers for Walls 125mm with Flyscreen Mesh Round Vent, for Duct, Tumble Dryer Vent Cover, Caravan, External Vent Cover

used for air heater install for air intake screen.Great fit and good product for my requirements.

Great size for the aperture ( internal extractor outlet ) and quality was very good for price. The sprung “propeller” fixtures gave a good tight fit first time and I did a test remove and refit. How excited can you get over a vent. Reasonably is the answer

Arrived on time, fitted perfectly, is doing it's job. Great.

Took a lot of effort to get in as wasn't sure how big a hole to cut. I opted for slightly too small a size so was a struggle getting it to fit but it's not going to move for sure. Was easy enough to connect ducting onto opposite side with a cable tie.Fitted onto soffit to remove heat from bathroom and doing a great job

Used in a hard to reach tiny soffit on a dormer.Managed to squeeze between vertical hung tiles and back of fascia, added 500mm of 3 inch flexible duct to the back of it and converted to 4 inch in the dormer loft. Reduces air flow a little but gets you out of a tight spot…literally!Extractor still extracts at a good rate and clears steam from shower no problem.

Used as part of an air handling system

Good Product, but no mention of Temperature Ratings. ~70c the white plastic melted and shrivelled up.

Overall looks good and easyish to fit. The pre drilled holes on the mounting flange were a little too near the inside so may be a problem mounting in a brick wall. To be honest I have 6" soil pipe through my cavity wall and it fits snugly in it.

Facile à poser, cette grille de ventilation est esthétique et efficace !

Materiale resistente

De momento cumple su función. Hay que ver como de duradera es con la exposición al sol y cambios de temperatura.

Pros: Muito Facil de instalar.Cons: Para proceder à limpeza da rede mosquiteira tem que se desmontar todo o sistema o que pode levar a despesas extra aquando da remontagem.
