Should my customer be concerned on how noisy the Arzel dampers may be?

How well do Arzel dampers seal the duct and stop air flow?
  • Arzel dampers are among the few in the industry that offer a gasket around the perimeter of the blade which ensures a nearly airtight seal on every Arzel’s branch or trunk dampers.
Will my existing Arzel dampers work with the new panel I am installing?

How can I tell if my Arzel damper is open or closed?
  • For dampers with an actuator mounted outside of the ductwork (i.e. Ezyslide), a yellow tab can be found that points to open or close. If the actuator is mounted inside the ductwork, the damper blade must be in sight to determine whether it is open or closed.
