The Manrose 100mm (4") Cowl Vent is a high-quality, weatherproof external wall vent cover designed to protect duct terminations from rain, wind, and debris. Suitable for both domestic and commercial applications, this vent is ideal for use with extractor fans, tumble dryers, and general air ventilation systems. The aerodynamic cowl design reduces the risk of backdraughts and ingress of water, while also preventing blockages from leaves and other environmental elements.
With a multi-fit connection, this vent is compatible with most 100mm round ducting systems, making it versatile and easy to install. Available in White or Brown, the cowl vent seamlessly blends with different external wall finishes, offering both function and discreet appearance.
Key Features
- Weatherproof Protection: Designed to shield duct openings from rain and wind, improving system longevity and performance.
- Multi Fit Compatibility: Compatible with all standard 100mm (4") round ducting, flexible or rigid.
- Anti-Backdraught Design: Helps reduce draughts by deflecting air and preventing reverse airflow into the property.
- Durable Plastic Construction: UV-resistant and corrosion-resistant plastic ensures durability in outdoor conditions.
- Discreet Styling: Available in White or Brown to match or complement most external wall surfaces.
Typical Applications
- Kitchen extractor fans
- Bathroom ventilation systems
- Tumble dryer venting
- Utility room or general-purpose ventilation
- HVAC systems
Installation Notes
- Mount on an external wall using appropriate fixings and sealant.
- For optimal performance, pair with 100mm ducting and ensure an airtight seal to avoid efficiency loss.
- Can be installed vertically or horizontally depending on the direction of airflow and wall design.
FAQ
Q: Is this vent suitable for tumble dryer installations?
A: Yes, it is commonly used for tumble dryer and fan exhausts to prevent moisture and debris from re-entering the duct.
Q: Will this stop cold air from entering my home?
A: The cowl design helps minimize backdraughts but does not completely eliminate airflow—use with a backdraught shutter for additional protection.
Q: Can this be painted?
A: While it's available in two standard colours, it can be painted with suitable exterior-grade paint if desired.
Q: How is it secured to the wall?
A: It features pre-formed screw holes for direct mounting. Use screws and sealant appropriate for your wall type (brick, render, timber, etc.).
