## Summary description

The DOSPEL RKO backdraft shutter is designed for 120 mm diameter ventilation ducts. It effectively prevents backflow of air into the room when the fan is turned off, ensuring optimal ventilation efficiency. Made from durable materials, this accessory is easy to install and compatible with standard ventilation systems, making it an essential component for maintaining air quality in residential and commercial spaces.

## Long description

The DOSPEL RKO backdraft shutter for 120 mm ventilation ducts is a specialized component designed to prevent the reverse flow of air in ventilation systems. When the exhaust fan is deactivated, the shutter automatically closes, effectively blocking cold air, odors, or dust from entering the room from the outside or from shared ventilation shafts. This ensures that the ventilation system maintains its intended airflow direction and improves the overall climate control within residential or commercial interiors.
Advantages
The primary benefit of the DOSPEL RKO shutter is its ability to enhance the efficiency of your ventilation system by eliminating unwanted air backflow. Constructed from high-quality, durable materials, this shutter is built to withstand the conditions typically found in ventilation ducts. Its design is optimized for simple installation, allowing it to be integrated into existing 120 mm ductwork without the need for complex tools or professional assistance. By preventing air from returning into the room, it helps maintain a cleaner and more comfortable indoor environment.
Suitable for
Residential bathrooms and kitchens
Small office ventilation systems
Preventing cold drafts in living spaces
Blocking odors from shared ventilation ducts
This shutter may not be suitable for high-pressure industrial ventilation systems or ducts with a diameter other than 120 mm. It is also not intended for use in environments with extreme temperatures or corrosive chemical vapors that could degrade the material of the shutter blades.
Key specifications
Compatible duct diameter: 120 mm
Material: Durable synthetic polymer
Function: Automatic backdraft prevention
Compatibility: Standard residential ventilation ducts
To install the DOSPEL RKO backdraft shutter, simply insert the unit into the 120 mm ventilation duct or attach it directly to the fan housing according to the manufacturer's instructions. Ensure that the shutter blades are oriented to open in the direction of the airflow and that the unit is seated securely to prevent vibration or air leakage around the edges. Once positioned, verify that the blades move freely and close completely when no air is being pushed through the duct.
What to consider before purchase
Verify the exact inner diameter of your ventilation duct is 120 mm
Ensure there is sufficient space within the duct for the shutter mechanism
Check the compatibility with your existing fan model
For optimal performance, inspect the shutter periodically to ensure it remains free of dust or debris that could impede the movement of the blades. Regular maintenance ensures the shutter continues to seal effectively and maintains the efficiency of your ventilation system.
