GUILLOTINE DAMPER
100% Clear Passage Zero Load-Loss Isolation 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.

Key Engineering Advantages
Zero Load Loss
When fully open, the damper blade retracts completely out of the gas stream, providing a 100% unobstructed passage.
Heavy Industrial Isolation
Delivers positive, reliable isolation for flue gas conduits, thermal oxidizers, and process duct maintenance shutdowns.
Electric Actuation Drive
Motorized rack-and-pinion or chain drive systems engineered for smooth blade travel even under high static pressure.
Easy In-Line Inspection
External access panels and low-maintenance guide rollers allow convenient inspection without duct dismantling.

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.
LOUVER (FLAP) TYPE DAMPER
The Louver (Flap) Damper is a heavy‑duty industrial flow control device designed for high‑temperature and harsh environments. Its blades can be arranged in parallel or opposed positions, oriented vertically or horizontally, and customized in size to match duct requirements. Built from high‑strength alloys, it offers tight shut‑off, high efficiency (85–92%), low leakage (<2%), and reliable operation with manual, pneumatic, or electric actuators.
