In the same way, spherical diffusers are frequently coupled using a radial damper or perhaps a crown damper although not an opposed-blade damper.
Ducted air-source warmth pumps have significantly less specific zoning capabilities Except if they’re equipped with a modern zoning system that includes dampers.
