## Summary description

The DOSPEL RKO backdraft shutter is designed for 125 mm diameter ventilation systems. It effectively prevents backflow of air, ensuring efficient ventilation performance. This durable component is easy to install in standard ductwork, making it an essential accessory for maintaining optimal airflow direction in residential or commercial ventilation setups.

## Long description

The DOSPEL RKO backdraft shutter for 125 mm ventilation ducts is a specialized component engineered to regulate airflow direction within residential and commercial ventilation systems. By automatically closing when the fan is inactive, it effectively prevents the backflow of air, odors, and external pollutants from entering the premises through the ductwork. This shutter is designed for seamless integration into standard 125 mm diameter circular ventilation ducts, providing a reliable barrier that maintains the integrity of your indoor air quality.
Advantages
The primary benefit of the DOSPEL RKO shutter is its ability to enhance the overall efficiency of ventilation systems by ensuring that air moves only in the intended direction. Its robust construction ensures long-term durability and consistent performance even in demanding environments. The lightweight design facilitates easy installation without requiring complex tools or structural modifications to existing ductwork. Furthermore, it operates automatically based on air pressure, requiring no external power source or maintenance, which makes it a cost-effective solution for preventing unwanted drafts and heat loss.
Suitable for
Residential kitchen and bathroom ventilation systems
Commercial office air exchange setups
Preventing cold air ingress in ventilation ducts
Maintaining unidirectional airflow in exhaust systems
When it may not be suitable
This backdraft shutter is not intended for use in industrial environments involving high-temperature exhaust, aggressive chemical vapors, or heavy dust loads that could obstruct the movement of the shutter blades. It is also not suitable for ducts with diameters other than 125 mm, as an improper fit will prevent the shutter from functioning correctly.
Key specifications
Compatible duct diameter: 125 mm
Material: Durable plastic
Operation: Automatic gravity-based
Installation type: In-duct mounting
How to use
To install the DOSPEL RKO backdraft shutter, ensure the ventilation system is powered off. Insert the shutter into the 125 mm circular duct, ensuring the orientation allows the blades to open in the direction of the airflow. Secure the unit firmly within the duct to prevent vibrations during fan operation. Once installed, verify that the blades move freely and close completely when there is no airflow.
What to consider before purchase
Verify that your existing ductwork has a 125 mm internal diameter.
Ensure there is sufficient space within the duct for the shutter blades to open fully.
Check the airflow direction of your fan to ensure correct installation orientation.
Usage recommendations
For optimal performance, inspect the shutter blades periodically to ensure they remain free of dust or debris that could impede their movement. Proper installation is critical to ensure the shutter seals effectively when the fan is turned off.
