Backdraft damper for ventilation ducts – reliable protection against air backflow

The CAR 250 backdraft damper is an element of a mechanical ventilation system designed to prevent unwanted air backflow in round ducts. Installing the damper guarantees maintaining proper airflow and efficient operation of the entire system. This is particularly important in installations where switching off the fan can lead to the penetration of odors or contaminants back into the room.

Design and application

Made of high-quality materials, the CAR 250 damper combines durability and functionality. The housing made of galvanized steel sheet provides corrosion resistance, and the damper blades made of aluminum sheet guarantee lightness and smooth operation. The "butterfly" mechanism, closed with a spring, allows the damper to be mounted in any position – vertical or horizontal – without affecting its effectiveness. The damper is used both in domestic and industrial installations, wherever protection against air backflow is required.

Advantages and benefits:

• Effective protection: Prevents air backflow, maintaining cleanliness and freshness in rooms.
• Durable construction: Made of galvanized steel and aluminum – resistant to corrosion and mechanical damage.
• Universal mounting: Possibility of installation in any position thanks to the spring mechanism.
• Simple installation: The damper is easy to install in standard round ventilation ducts with a diameter of 250 mm.
• Reliable operation: The "butterfly" mechanism ensures a tight closure of the damper after the fan is switched off.
• Long-term use: Solid construction guarantees trouble-free operation for a long time.

It is worth remembering that proper selection of the damper diameter to the ventilation duct diameter is crucial to ensure optimal system performance. The CAR 250 damper is intended for ducts with a diameter of 250 mm.
