Back-draught shutter | damper | for ducts | ventilation systems | D125 | plastic | 125AV

Technical Specifications:

Color: White
Material: ABS plastic
General depth: 8.5 mm
Mounting diameter: 125 mm
Outer diameter: 125 mm
Usage: The back-draught shutter is used in ventilation systems where it is necessary to protect rooms from unpleasant odors and air returning back into the room. This shutter is especially useful in bathrooms, kitchens, and other areas. Its spring mechanism ensures complete tightness when the system is not in operation, preventing airflow from returning.

Advantages:

Effective protection against backflow: The shutter ensures that unpleasant smells and air do not return into the room.
Durable and long-lasting: Made of ABS plastic, which is resistant to moisture, heat, and other environmental conditions.
Spring mechanism: Completely seals the airflow when the ventilation system is off, preventing any backdraft.
Easy installation: Suitable for 125 mm diameter ducts, making it easy to integrate into existing ventilation systems.
Disadvantages:

Limited compatibility: Only suitable for 125 mm diameter ducts, making it incompatible with other sizes without additional adaptation measures.
Plastic durability: While ABS plastic is resistant to many factors, it may be vulnerable to mechanical impacts or prolonged use in environments with higher loads.
Requires regular checks: Since the shutter operates with a spring mechanism, it needs to be periodically checked to ensure it closes properly and functions smoothly.
