⚡ At a Glance
- • Weather Protection: Blocks wind, rain, snow and small wildlife
- • Best for: Homeowners fitting external 100 mm dryer or bathroom ducting
- • Not ideal for: Non-standard duct sizes or bespoke ventilation systems
Outdoor vent cover fits 100 mm ducts, using a one-direction non-return valve and curved louvers. Construction in ABS plastic with UV inhibitors helps resist sun damage and cracking.
Keeps weather and pests out - with curved louvers and durable ABS
Curved louvers create a physical barrier and redirect airflow to limit direct water entry, while ABS plastic delivers rigidity and impact resistance. UV-stabilised material reduces brittle failure from sun exposure.
Reliable protection from rain, wind and birds for external vent openings. Durable materials mean fewer replacements and less maintenance.
Reduces backdrafts - with a one-direction non-return valve
One-direction flap allows air to exit while closing against incoming flow, preventing reverse air movement. The design relies on a simple mechanical flap rather than electrical parts.
Backdrafts and cold gusts are kept out, improving home comfort and preventing unpleasant smells entering interiors. Suitable for dryer exhaust and bathroom fans where reverse flow is a concern.
Neat external finish and easy mounting - with standard screw-hole spacing
External dimensions are 153 x 148 mm with screw holes spaced 111 x 95 mm and a 100 mm vent opening, designed to match common duct sizes. Shallow 30 mm connecting depth keeps the profile low against the wall.
A tidy, low-profile appearance that sits flush on most external walls. Straightforward alignment with existing ducting makes replacement or retrofit installation quicker.
