Damper

The Gravity Explosion Relief Door is a reusable overpressure safety device for boilers, flue ducts, coal pulverizing systems, and dust collectors. Its counterweight-hinged flap opens automatically at preset pressure and gravity-resets after relief, requiring no power or replacement.

The Industrial Flue Gas Non Return Damper is a self-acting check damper that prevents backflow when fans stop. Designed for flue gas, hot air, and dusty gas up to 400°C, it operates automatically by airflow without an external actuator.

The Flue Gas Diverter Damper uses a single- or double-leaf design to switch or distribute boiler flue gas between two outlets. Suitable for dusty hot gas up to 420°C, it supports electric, pneumatic, or hydraulic actuation with customizable sealing.

The Flue Gas Flap Damper (Industrial Bypass Flap Damper) is a heavy-duty single-leaf swing damper for bypass or emergency shut-off in large rectangular ducts. Designed for dusty, high-volume flue gas up to 420°C, it supports electric, pneumatic, or hydraulic operation.

The Rectangular Volume Control Damper uses multiple parallel louver blades for continuous airflow and flue gas regulation in rectangular ducts. Suitable for temperatures up to 400°C, it supports manual, electric, or pneumatic actuation and is ideal for duct airflow balancing.

The Flue Gas Butterfly Damper features a compact circular single-disc design for fast flow control or shut-off in round ducts. Suitable for flue gas, hot air, and clean gas up to 400°C, it offers manual, electric, or pneumatic actuation and Class IV–VI sealing.
