Isolation Dampers

Sealed Air Damper

Product overview

FORENSERVTEK sealed air dampers are the ideal solution for applications requiring 100% sealing of flue gas and process gases.
Our sealed air design operates by continuously maintaining a pressure higher than the upstream process pressure to preserve the seal clearance of the damper blades.
Our flexible special-alloy seals retain durability even at high temperatures, making them well suited for heavy-duty applications.
Butterfly, multi-louver, guillotine and diverter dampers can all be equipped with sealed air systems to achieve 100% tight shut-off.
FORENSERVTEK can design and supply complete sealed air systems, including air ducts, heaters, return air units, fans and mounting accessories.
We evaluate the specific process data of your project to calculate and determine the optimum fan size, power consumption and sealed air control strategy for your requirements.
Fans and control units can be supplied with relevant certifications for use in hazardous areas, such as ATEX.
