“aira” Pneumatic Actuator Operated Butterfly Damper is designed for applications where tight sealing is less critical. Ideal for flue-gas scrubbers, it offers a lightweight, cost-effective solution with simple 90° motion. It can adapt to oval ducts and features a straightforward drive mechanism. However, torque requirements may vary due to corrosion and thermal effects over time.
