PATIKIL 6in Stainless Steel Backdraft Damper, Silver

PATIKIL 6 Inch Backdraft Damper is a high-quality, durable stainless steel airflow solution designed to prevent backflow in kitchen, bathroom, and HVAC exhaust systems. The damper features a 149mm (5.87in) outer diameter interface and compact dimensions of 190 x 190 x 42mm (7.48 x 7.48 x 1.65in), making it ideal for tight spaces.

Crafted from corrosion-resistant 201 stainless steel, this backflow preventer resists moisture, scratches, and rust while ensuring long-lasting performance. The spring-loaded valve opens automatically during exhaust fan operation, allowing air to flow freely. Once the fan stops, the damper closes tightly, blocking odors, dust, and debris from re-entering your home. Easy to install with spring clips and sealing glue (not included), it’s perfect for dryers, range hoods, and ventilation systems in kitchens, bathrooms, offices, or living spaces.
