Repa Market Galvanized Steel 4 Inch Duct Backdraft Damper - One-Way Airflow HVAC Damper, Dryer Vent Damper, Metal Inline Backdraft - 4 Inch Duct Damper, Dryer Duct Connector with Backdraught Flap
FITS 4 INCH DUCTING SYSTEMS – MALE FIT NECK DIAMETER 3.89". TOTAL LENGHT 3.46". Precision-engineered for a tight internal fit inside metal ventilation pipes or ducts for reliable, airtight performance.
DURABLE CONSTRUCTION - ALUMINUM AND GALVANIZED STEEL DAMPER – 4 backdraft damper made from heavy-duty galvanized steel with aluminum blades and noise-reduction padding – built-in foam seal improves airtightness, reduces noise, and ensures smooth, quiet flap operation while preventing drafts and backflow.. Built to withstand high temperatures from -4°F up to 212°F, moisture, and continuous use in dryer vents, kitchen exhausts, HVAC ductwork, and heating systems.
AIR BACKDRAFT CONTROL – 4 inch backdraft damper features dual spring-loaded flaps that open only in the outflow direction, stopping reverse airflow, cold air, odors, and unwanted drafts while keeping HVAC duct systems efficient and quiet. Compatible with all round ducting systems, flexible or rigid, metal or plastic pipes, dryer vent systems.
EASY INSTALLATION – The backdraft damper is engineered for operation in a single airflow direction. Installing it in reverse will prevent proper function. Simple, tool-free installation—just insert the damper into the duct. For flexible ducts, secure with clamps for a tighter fit; for rigid ducts, use aluminum tape or mounting adhesive to ensure a stable connection (mounting accessories not included). Ideal for use in bathroom exhaust fans and kitchen ventilation systems.
WIDE HVAC APPLICATIONS – Designed as a backdraft shutter for air conditioners, dryers, cooker hoods, bathroom exhausts, inline ventilation fans as exhaust fan damper, range hoods, inline vent draft blocker and heating ducts. Works with rigid or flexible metal ducting and spiral pipe connectors, ensuring efficient backflow prevention in residential and commercial ventilation.
