Back-draught shutter | damper | for ducts | ventilation systems | D100 | plastic | 100AV

Technical Specifications:

Color: White
Material: ABS plastic
General depth: 7 mm
Mounting diameter: 100 mm
Outer diameter: 100 mm
Usage: The back-draught shutter is used in ventilation systems where it is necessary to protect rooms from unpleasant odors and air flowing back into the room. This shutter is especially useful in bathrooms, kitchens, and other areas. Its spring mechanism ensures complete sealing when the system is not operating and prevents air flow from returning.

Advantages:

Effective protection against back-draught: The shutter ensures that unpleasant odors and air do not return to 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 air flow when the ventilation system is not working, preventing any back-flow of air.
Easy installation: Suitable for 150 mm diameter ducts, making it easy to integrate into existing ventilation systems.
Disadvantages:

Limited compatibility: Suitable only for 150 mm diameter ducts, so it is not compatible with other sizes without additional adaptation tools.
Durability of plastic: Although ABS plastic is resistant to many factors, it can be damaged by mechanical impacts or long-term use in environments with higher load.
Requires regular checking: As the shutter operates with a spring mechanism, it needs to be periodically checked to ensure it closes properly and works without interference.
