Reliable anti-odor check valve with a 100 mm diameter and a dual-flap magnetic membrane that effectively prevents backflow and odor ingress from the ventilation system. Thanks to its self-closing action, rubber sealing around the perimeter, and quality materials (ABS and silicone), it provides excellent tightness, long service life, and quiet operation—ideal for range hoods and ventilating bathrooms and toilets.
This dual-flap anti-odor check valve is designed for installation in round ducting with a 100 mm diameter. Magnetic force and a flexible silicone membrane ensure reliable and quiet closure when the fan is off, effectively preventing the return of air and odors back into the room.
The construction from durable ABS plastic, complemented by a U-shaped rubber seal around the entire perimeter, increases tightness, stability in the duct, and minimizes vibrations. With simple push-in mounting into a round duct, installation is quick and tool-free.
- Effective backflow prevention – dual-flap, magnetic, and self-acting membrane.
- High tightness – U-shaped rubber perimeter seal for a secure fit in the duct.
- Durable materials – ABS body, silicone membrane.
- Easy installation – simply push into a round duct.
- Wide application – range hoods, bathroom and toilet ventilation.
- Thermal resistance – long-term up to 80 °C, short-term up to 85 °C.
- Optimal with a radial fan – recommended for maximum efficiency.
