Unitech works with Tamco (1) to provide a high end low leakage, low maintenance damper that will last the life of our custom products. This damper’s all-aluminum construction provides a prolonged and rust-free operational life. Dampers are assembled using slip-proof linkage components that keep blades aligned as per factory adjustment. These dampers are supplied with extremely flexible silicone side seals and EPDM blade seals, that are resistant to weathering, compression set, and heat. Damper seals provide outstanding dynamic fatigue resistance, ensuring consistent minimal leakage rate performance and sealing longevity. Damper dual bearing system is self-sealing, self-lubricating, and non-absorbent, resulting in totally maintenance-free performance.

Unitech offers a thermal dispersion technology damper as built by Ebtron (2) or products built by Greenheck (3) to measure pressure differential. Thermal dispersion technology is typically offered on outside air intakes. Pressure differential technology is offered in a larger variety of applications. Pressure differential probes can be factory mounted on fan inlet cones.
