SLIDING DAMPER
Robust Flat-Plate Sliding Mechanism for Flow Shut-Off
The Sliding Damper is a simple and durable flow control Equipment used in ducts and pipelines. It operates with a flat plate that slides horizontally or vertically to regulate or shut off air and gas flow. Available in sizes from 100 mm to 1800 mm, it offers reliable efficiency (90–95%), moderate sealing, and easy operation with manual, pneumatic, or electric actuators. Its rugged design ensures long service life with minimal maintenance.

Key Engineering Advantages
6 mm - 20 mm Solid Plate
Heavy plate thickness tailored to duct static pressures, offering structural rigidity and resistance to warping.
Manual / Motorized Versatility
Operable via manual hand-wheel with gear reduction, pneumatic push-pull cylinder, or electric actuator.
Self-Cleaning Gate Rails
Slide track geometry prevents particulate build-up and ensures reliable full closure in dirty dust-laden airflows.
Simple, Rugged Mechanics
No complex internal linkages—ideal for cement plants, foundries, exhaust lines, and heavy industrial facilities.

Complementary Damper Solutions
COFFEEPOT DAMPER
The Coffee Pot Damper is a strong and reliable safety damper used in HAG and attached on hot-air ducting systems. It is designed to handle high temperature and pressure conditions. The damper can be operated by a pneumatic cylinder or electric actuator, while the counterweight arrangement helps in quick opening during emergency situations. Its simple, robust design makes it suitable for safe industrial operation.
MULTILOUVER DAMPER
The Multilouver Dampers are used for airflow regulation and isolation in ventilation, fans and industrial air-handling systems. The damper has multiple adjustable louvers mounted in a strong fabricated frame, which helps in smooth and uniform air control with low pressure drop. Louvers are connected through an external linkage for easy and synchronized operation. The damper can be provided with manual or motorized operation and customized in size, material and arrangement as per application requirements.
GUILLOTINE DAMPER
The Guillotine Damper is a heavy-duty damper designed for reliable ON-OFF isolation of air, gas and process ducting systems. It is available in Round and can be manufactured as per required duct/flange dimensions. The damper is suitable for high-temperature and industrial applications where low pressure drop, easy inspection and maintenance are required. When fully open, the passage remains clear, resulting in minimum load loss.
