@tonymormino: The correct airflow is critical in dynamic environments like labs and surgery suites. From adjusting CFM to managing exhaust valves, we ensure that every room maintains perfect pressure and safety standards. Dive into our video, where we explore the meticulous setup of air valves and actuators, keeping these essential spaces precisely pressurized. Thank you George Vailliant, for this excellent information.
