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. ## Features - Adjustable air vents: Adjust the airflow by rotating the disc in the centre. It can also be turned off completely. - Easy to install: The ‘fin’ at the end is designed to help hold it in place. Can be mounted on ceilings and walls (inside and outside). - Wide applications: The round ceiling vent is ideal for ventilating bedrooms, bathrooms, kitchens, caravans, air conditioning system, etc. It can be used to connect to 100mm diameter ducts, exhaust fans, cooker hoods, etc. - Round design: Compact and delicate. Removable and easy to clean, just wipe the surface with a damp rag and it will shine like new. - Well-made: made of excellent plastic, sturdy and wear-resistant, odourless and safe. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BHL4MVL | | Best Sellers Rank | 4,381 in DIY & Tools ( See Top 100 in DIY & Tools ) 10 in Registers, Grilles & Vents | | Brand | Hon&Guan | | Brand Name | Hon&Guan | | Colour | White | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 550 Reviews | | Finish Type | Matte | | Included Components | Mounting Hardware | | Indoor Outdoor Usage | Indoor | | Installation Type | wall and ceiling mounted | | Is Product Cordless | No | | Item Type Name | Air vent cover | | Manufacturer | Hon&Guan | | Material | Acrylonitrile Butadiene Styrene | | Model Name | vent cover | | Mounting Type | Wall Mount/Ceiling Mount | | Mounting type | Wall Mount/Ceiling Mount | | Number of Power Levels | 1 | | Power Source | Manual | | Power source | Manual | | Product Warranty | 2. | | Size | ø100 mm | | Special Features | Adjustable Airflow | | Special feature | Adjustable Airflow | | Style | ø100mm | | UPC | 767550224453 | | Unit Count | 1.0 count | ## Product Details - **Brand:** Hon&Guan - **Colour:** White - **Finish type:** Matte - **Included components:** Mounting Hardware - **Indoor/Outdoor usage:** Indoor - **Material:** Acrylonitrile Butadiene Styrene - **Mounting type:** Wall Mount/Ceiling Mount - **Power source:** Manual - **Special feature:** Adjustable Airflow - **Style:** ø100mm ## Images ![4 Inch Adjustable Air Vent Covers 100mm Ceiling Vent Indoor Vent for Walls Closeable Round Ventilation Cover for Caravans, Cooling and Ventilation Systems, No drilling - Image 1](https://m.media-amazon.com/images/I/51HqwM+O8aL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great vent *by P***. on 13 May 2026* Great product as expected snd good seal ### ⭐⭐⭐⭐⭐ Looks good and easy to fit *by C***R on 16 August 2024* 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.
