The CRDS series are galvanized steel, one blade dampers compete with a 24 V, spring return motor actuator. These dampers are shipped complete and ready for installation. The CRDS can be installed in any position in any properly sized duct. All CRDS dampers are rated for duct systems less than 1 in-WC. All CRDS dampers are typically shipped as normally open dampers that are powered closed and spring returned opened. The CRDS is also unique in that it can be field converted from powered closed to powered open in less than a couple of minutes.
