FRP Damper Valves: Butterfly & Louver Airflow Dampers for Acid Fume Exhaust Regulation
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 […]
