Introduction: Balancing Corrosive Exhaust Airflows
In multi-point fume extraction networks, balancing airflow from multiple pickup hoods into a central scrubber requires precise, corrosion-resistant control dampers. Standard metal dampers corrode and seize within weeks of acid exposure.
1. Types of FRP Dampers
- Butterfly Dampers: Single-blade circular disc rotating on a solid vinyl ester shaft with Teflon bushings. Provides precise throttling control and tight shut-off.
- Parallel / Opposed Blade Louver Dampers: Ideal for large rectangular duct sections and scrubbers where low operating torque is essential.
