Product Description

Industrial Dampers

Since the past 7 years, our organization has been renowned appreciation as the topmost manufacturer, exporter and supplier of Industrial Dampers like Electrically Operated Dampers, Square Louver Damper, Bypass Damper, High Temperature Damper and others. Extensively used in commercial and industrial sectors, the offered industrial dampers acts as a valve to regulate the air-flow within the installed spaces. The provided damper is manufactured by our adroit professionals using utmost quality components and contemporary techniques in line with international quality standards. Available in different designs and technical specifications, these Industrial Dampers is offered to the clients at reasonable prices.

Damper Performance 

  • Leaking Ratings : For the dampers, leakage increases significantly with blades number, than with the blades length.

  • Torque Requirements : Closing Torque: The torque needed to power the blades together to sufficiently accomplish minimal possible leakage.

  • Dynamic Torque: Need to overcome the high velocity airflow effect over the blades.

  • Velocity Ratings : Higher velocity of industrial dampers in comparison to other shows that the former damper has stiffer blade. Also, linkage design that the bearings may be competent of higher loads.

  • Temperature Ratings: Seals and Bearings are constructed of heat resistant material, if temperature rating is high.

  • Pressure Ratings: When the blades are closed, maximal static pressure differential may be practical across the assembly.

  • Ul Classification (fire/smoke) : UL 5555 (Regulation for Leakage Rated Dampers, for smoke control systems use)


Design Characteristics

Material Selection:


The material selection is characterized as per the operational conditions to which the industrial dampers will be exposed. This helps to ensure the best equipment performance. Gases from carbon combustion & fuel-oil, from cement factories, with sulphur, metal oxide, chloride etc. may reason early wear and troubles with corrosion, which should be analyzed in all cases.

Sealing Efficiency:

Closing degree of Industrial Damper is measured as an equivalent open area percentage. In other terms, an industrial damper with closing degree of 99% is equivalent to have 1% of the conduit area open. In reality, the flow leakage percentage is from 3 to 6 times said area, hence a damper with 99% closing degree will permit leakage of from 3% to 6% of the gas flow. 

Damper Actuators

Industrial Damper Actuators can be regulation type or on/off type to which a position transmitter signal or positioner may be added for the purpose of automation.

Damper Actuator Types

  • Wheel & Gearbox: Manual actuator system is appropriate for units that do not have a high automation level, and with small sized dampers.

  • Pneumatic: With 1⁄4 turn cylinder or linear; rendering very fast actuation. Involves a 5 to 7 bar air-pressure line. An air tank may be enclosed for emergency override.

  • Electric: Multi-turn electric motor or 1⁄4 turn electric motor, with gear box; supplied with a manual wheel for emergency override.
