These 4 in. backdraft dampers are designed for versatile ventilation control. They are constructed from galvanized steel with a powder coat finish, while the flap leaves are made from aluminum to resist corrosion and maintain smooth operation. When installing, push the damper into the ventilation pipe as far as it will go, and orient the spring so it sits horizontally with the flap in its intended horizontal position to allow optimal opening and closing. The design works with the TD lip to regulate airflow and helps prevent air from re circulating when the fans are not running, which can improve overall duct performance. They suit a range of residential, commercial, and industrial applications, including air conditioning units, exhaust fans, range hoods, and heating ducts, and can be used in various duct layouts. Each package includes two dampers and they can be inserted into both flexible and non flexible ducts. Plastic ducts are not compatible due to size differences, so verify duct type before selecting these dampers to ensure proper fit and performance. All dimensions are measured by hand with a typical tolerance of about one to three millimeters in production and may vary slightly. This type of damper offers a straightforward solution for controlling backdrafts without needing additional hardware. The drive for easy installation means teams can implement these dampers with minimal disassembly, providing steady airflow control across fluctuating loads. Color: Black.

A set of backdraft dampers is included, each with a 4 in. (100 mm) diameter to fit common ventilation lines. The housing is built from galvanized steel, and the closing leafs are aluminum, balancing durability with lightweight operation. The pair is designed to be installed by pushing into the duct until seated, and the spring should be oriented so the flap sits horizontal when the pipe runs horizontal, a rule that also applies to vertical installs. When active, the device helps regulate airflow by reacting to changes in fan status, preventing backflow and reducing recirculation through the system when the fan stops. It is compatible with both flexible and non flexible ducts, though it should not be used with plastic ducts because of size differences that affect seating and sealing. This type of damper is commonly applied in various ventilation paths, including air conditioning lines, exhaust and range hood ducting, heating conduits, vents, and related residential, commercial, or light industrial installations. It offers a straightforward, mechanical solution for controlling air movement without electronics, relying on gravity and spring tension to operate the flap. Always verify the diameter before installation and ensure the chosen segment of duct can accommodate the 4 in. profile. Color: Silver.

Designed for ventilation systems, these 6 in. backdraft dampers are built from galvanized steel with aluminum flap leaves to balance strength and lightness. The assembly includes two dampers sized at 6 in. (150 mm) in diameter, suitable for standard ducts and compatible with flexible or non flexible runs. Manual tolerances apply as dimensions are measured by hand, so allow a small variance during installation. Installation is straightforward: insert the damper into the duct until it sits securely, ensuring the spring mechanism positions horizontally when the flap is installed to optimize opening and closing. This orientation helps prevent unwanted air flow when the system is off, while allowing free movement when air is directed through the line. The device acts as an airflow regulating backdraft shutter that fits over the TD lip, providing a barrier to reverse flow and helping to maintain directional ventilation. It is not designed for use with plastic ducts due to size differences. When selecting a location, consider flow path geometry and access for future maintenance. It can be used across a range of settings including HVAC components, exhausts, range hoods, heating ducts and general vents in residential, commercial and light industrial environments.

These backdraft dampers are designed to regulate airflow in ventilation systems by preventing reverse air movement when fans are off. The unit comprises two dampers with an 8 in. (200 mm) diameter, constructed from galvanized steel with aluminum flap leaves for lightweight operation. Dimensions are measured manually, so minor variances of 1–3 mm may occur. The dampers install by sliding into the duct until fully seated, with the spring positioned horizontally when the flap is installed horizontally to ensure reliable opening and closing in both horizontal and vertical orientations. They are suitable for ducts that are flexible or non flexible, but not compatible with plastic ducts due to size differences. The assembly functions to reduce backflow and recirculation, helping to maintain directional airflow in systems such as air conditioning, exhausts, range hoods, and other residential, commercial, or industrial applications. When selecting a location, consider the lip dimensions and the absence of obstructions that could prevent the flap from operating freely. These dampers are intended for use where a simple, passive backflow control is appropriate and where regular access for inspection is possible. Care should be taken to confirm compatibility with existing duct lip profiles and to avoid interference with other components during retrofits. Color: Silver.
