## Summary description

The DOSPEL RKO backdraft shutter is designed for 100mm diameter ventilation ducts. It effectively prevents backflow of air, ensuring efficient ventilation system operation. This durable accessory is suitable for residential and commercial exhaust systems, helping to maintain optimal air quality and preventing unwanted odors or cold air from entering the room through the ventilation duct.

## Long description

The DOSPEL RKO backdraft shutter is a specialized component engineered for 100mm diameter ventilation ducts. Its primary function is to prevent the backflow of air, which ensures that your ventilation system operates with maximum efficiency. By acting as a one-way valve, this accessory effectively blocks unwanted odors, dust, and cold air from entering your living or working space through the exhaust duct, thereby maintaining a consistent and comfortable indoor climate.
Advantages
This backdraft shutter offers a reliable solution for improving the performance of exhaust ventilation systems. Its robust construction ensures long-term durability and consistent operation even under varying pressure conditions. The design is optimized for easy integration into standard ventilation setups, providing a seamless barrier that opens only when the fan is active and closes automatically when the airflow stops. This prevents energy loss and helps maintain the desired temperature and air quality within the room.
Suitable for
Residential bathroom and kitchen exhaust systems
Commercial ventilation setups requiring backflow prevention
Offices and small retail spaces with standard 100mm ducting
Preventing cold drafts in rooms connected to shared ventilation shafts
When it may not be suitable
This shutter is specifically designed for 100mm diameter ducts and will not fit systems with different dimensions. It is intended for use with standard exhaust fans and may not be compatible with high-pressure industrial ventilation systems or specialized HVAC equipment that requires specific pressure-rated dampers.
Key specifications
Diameter: 100 mm
Material: Durable plastic construction
Function: Automatic backdraft prevention
Compatibility: Standard circular ventilation ducts
How to use
Installation of the DOSPEL RKO backdraft shutter is straightforward and typically involves inserting the unit directly into the ventilation duct or attaching it to the outlet of a compatible exhaust fan. Ensure that the shutter is positioned correctly so that the flaps can open freely in the direction of the airflow. Once inserted, secure the unit to ensure it remains stable during fan operation. Regular inspection is recommended to ensure that the flaps remain free of dust or debris that could impede their movement.
What to consider before purchase
Verify the internal diameter of your existing ventilation duct is exactly 100 mm
Ensure there is sufficient space within the duct for the shutter mechanism
Check the orientation of your duct to ensure the shutter can operate vertically or horizontally as required
Usage recommendations
To maintain optimal performance, periodically clean the shutter flaps to remove accumulated dust or grease. This ensures the mechanism remains responsive and continues to provide an effective seal against backdrafts.
