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.

FORENSERVTEK Offset Disk Dampers (Also known as 3-lever Valves) are the optimal choice for applications where butterfly dampers cannot achieve full tight shut-off, as the shaft penetration point of butterfly dampers always creates a sealing discontinuity and becomes a potential leakage source. They are also ideal when an air sealing system is not available on-site and installation space is insufficient for guillotine dampers, especially for media containing relatively few viscous impurities.
Under high-temperature and variable-temperature conditions, the expansion and contraction deformation of the valve body and disc of FORENSERVTEK Offset Disk Dampers will not affect the sealing performance, eliminating the risk of jamming. The sealing surface forms a continuous 360° inner perimeter, providing a full contact surface when the blade is closed, thus enabling zero leakage. This makes them an ideal solution for industrial equipment isolation.
