Its compact size and sleek black finish ensure easy installation and seamless integration, helping to prevent unwanted drafts and improve overall ventilation performance. ## Description Product Description A ventilation duct tool designed to insert into a 4" duct to prevent cold vents and debris from entering the ventilation system. Designed to be embedded into the duct, the backflow prevention damper is made of heavy duty galvanized steel with two outer rubber gasket rings. This allows the duct to be securely gripped in either horizontal or vertical orientation. Butterfly Damper Blade is made of aluminum and features a lightweight spring that folds down with minimal air flow. Application Spring Loaded Backflow Damper is built to last for kitchen overhead range hoods, bathroom fans, tumble dryers and more. Use rubber rings to insert completely or partially into the duct to hold it in place. Other unidirectional air flow applications include turning on the water heater pilot light or keeping debris out of the inline duct fan of the cultivation tent. ## Features - Anti-draft duct insert designed for use with range hoods, bathroom fans, and other home HVAC applications ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | AC Infinity | | Model Number | AC-BDD4-B | | Product Dimensions | 12.7 x 9.68 x 9.68 cm; 318 g | | Color | black | | Included Components | Backdraft Damper | | Are Batteries Included | No | | Item Weight | 318 g | ## Product Details - **Brand:** AC Infinity - **Color:** Black - **Item dimensions L x W x H:** 5 x 3.81 x 3.81 inches - **Manufacturer:** AC Infinity - **Material:** Alloy Steel, Aluminum - **Size:** 4" - **UPC:** 819137021303 ## Images ![Ah C Infinity 4" place ckdraft damper, ridgeway airflow to chucking member with rt sp forest go a de forest gold g base 4" two chucking member lunge teak guide place lo th MS fan - Image 1](https://m.media-amazon.com/images/I/51lALiYTYEL.jpg) ![Ah C Infinity 4" place ckdraft damper, ridgeway airflow to chucking member with rt sp forest go a de forest gold g base 4" two chucking member lunge teak guide place lo th MS fan - Image 2](https://m.media-amazon.com/images/I/51jBoph3RiL.jpg) ![Ah C Infinity 4" place ckdraft damper, ridgeway airflow to chucking member with rt sp forest go a de forest gold g base 4" two chucking member lunge teak guide place lo th MS fan - Image 3](https://m.media-amazon.com/images/I/51Vig+xStqL.jpg) ![Ah C Infinity 4" place ckdraft damper, ridgeway airflow to chucking member with rt sp forest go a de forest gold g base 4" two chucking member lunge teak guide place lo th MS fan - Image 4](https://m.media-amazon.com/images/I/51JTxQHs5SL.jpg) ## Frequently Bought Together - AC Infinity 4" Backdraft Damper, One-Way Airflow Ducting Insert with Spring-Loaded Folding Blades for 4” Ducting in Range Hoods and Bathrooms Fans - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/729340562-ah-c-infinity-4-place-ckdraft-damper-ridgeway-airflow-to](https://www.desertcart.co.th/products/729340562-ah-c-infinity-4-place-ckdraft-damper-ridgeway-airflow-to) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
