## Long description

The VENTS KO150 backdraft shutter is a specialized component designed for 150mm diameter ventilation fans. It serves as a critical accessory for maintaining indoor air quality by preventing the backflow of air into the room when the ventilation system is inactive. Constructed from high-quality, durable materials, this shutter provides a robust barrier against unwanted external elements, ensuring that your ventilation system operates with maximum efficiency.
Advantages
This backdraft shutter offers a seamless solution for preventing the ingress of cold air, dust, and unpleasant odors from ventilation ducts. Its lightweight design ensures that it does not impede the airflow of the fan during operation, while its precise construction allows for a tight seal when the fan is switched off. The installation process is straightforward, making it a practical upgrade for both residential and commercial ventilation setups that require reliable backflow protection.
Suitable for
Residential bathrooms and kitchens
Commercial ventilation systems
Offices and utility rooms
Preventing cold drafts in winter
Blocking dust and external odors
This product may not be suitable for high-pressure industrial ventilation systems or environments where the ductwork diameter deviates from the standard 150mm size. It is also not intended for use in systems handling corrosive gases or high-temperature exhaust that could compromise the material integrity.
Key specifications
Compatibility: 150mm diameter ventilation fans
Function: Prevents air backflow
Material: Durable plastic
Application: Domestic and commercial ventilation
To install the VENTS KO150, simply insert the shutter into the ventilation duct or attach it directly to the fan housing according to the manufacturer's guidelines. Ensure that the shutter flaps are oriented correctly to allow for free movement and that the unit is securely seated to prevent vibration or noise during fan operation.
What to consider before purchase
Verify that your ventilation duct diameter is exactly 150mm
Check the available space for installation behind the fan
Ensure compatibility with your specific fan model
For optimal performance, inspect the shutter periodically to ensure that the flaps remain free of dust and debris, which could hinder their movement and reduce the effectiveness of the backflow prevention.
