Featuring a curved internal baffle and draft-reducing design, it improves airflow performance in exposed external wall installations.

This helps maintain comfort while supporting consistent airflow. The removable front cover allows quick access for routine cleaning and maintenance without removing the entire unit from the wall. An integrated drip tray helps manage moisture and protect the wall surface below. Manufactured with a non-flammable body, the vent cover is designed for safe use with modern residential and light commercial ventilation systems. The white finish provides a clean, contemporary external appearance. Applications Suitable for external wall installations in bathrooms, kitchens, utility rooms and whole-house ventilation systems. Ideal for use with extractor fans, MVHR, MEV, dMEV and single-room heat recovery units in domestic and light commercial properties. Installation Notes Designed for connection to standard 100 mm (4”) round ducting. Ensure the unit is securely fixed to the external wall surface using appropriate fixings for the substrate. Position to allow unobstructed airflow and ensure proper sealing around the duct connection to maintain weather resistance and system efficiency. Install in accordance with UK building and ventilation regulations where applicable.

Review: good quality - It does the job, finally the flap is quiet in the wind. My old one didn't let me sleep.
Review: Reduces the rattling noise from extractor fan - This has made a big difference by reducing the rattling noise from the extractor fan in the ensuite which was waking me up before. As others have mentioned, removing the cover wasn’t easy but once it was off, it was easy to install with the supplied fittings. Not the cheapest vent cover but worth it for a better night’s sleep!

### ⭐⭐⭐⭐⭐ good quality
*by K***A on 4 April 2025*

### ⭐⭐⭐⭐ Reduces the rattling noise from extractor fan
*by A***R on 15 November 2025*

This has made a big difference by reducing the rattling noise from the extractor fan in the ensuite which was waking me up before.

### ⭐⭐⭐⭐⭐ Easy to install. Looks great
*by T***O on 19 March 2026*

Extremely easy to install. A lot of reviews say its difficult to separate the two pieces (which I agree). The design seems ro suggest you neet to put a flathead screwdriver and open from the top, which in reality it needs to open from the BOTTOM! See attached manual. All diameters have the same screw placement (just a different diameter hole). Overall very pleased. I will update on how it behaves during high wind..
