Beteccad FD-GB-20-A-AS-B-BS-R Fire Damper

Ensure the safety and integrity of your HVAC systems with the Beteccad FD-GB-20-A-AS-B-BS-R fire damper. Engineered to meet strict safety standards, this damper is certified to UL 555 test ratings, providing a robust 1.5-hour fire rating to prevent the spread of fire and smoke through ductwork.

The unit features a standard construction with an 18-gauge (1.2 mm) thick galvanized steel frame, ensuring durability and resistance to corrosion. The curtain-type blade is crafted from 22-gauge (0.8 mm) galvanized steel, operating via a 165°F fusible link for automatic closure during a fire emergency. The blade ramp is reinforced with 16-gauge (1.5 mm) galvanized steel angle, and the mechanism utilizes a 0.3 mm thick by 19 mm wide stainless steel constant force spring for reliable operation.

Designed for vertical sleeve mounting, the damper supports minimum 0.7 mm sleeve thickness in compliance with NFPA Table 3-4.6.3. It is available with optional fittings including 1.5-inch retaining angles and limit switches for Building Management System (BMS) integration, allowing for open/close indication. For round duct connections, a neck adapter transition is available. While the standard configuration uses galvanized steel, optional stainless steel (304/316L) construction is available for specific environments, though UL certification applies only to the standard galvanized configuration.
