It ships with a Belimo 3-wire actuator, providing reliable open-close control in residential and light commercial zoning applications. The damper measures 28 inches wide by 12 inches tall and weighs 12 pounds. Licensed HVAC technicians install this unit as part of a multi-zone ducted system, where precise airflow control to individual zones improves comfort and system efficiency. The Belimo actuator delivers consistent torque and long service life, making this a dependable choice for new installations and retrofit work alike.\u003c\/p\u003e\n\u003cp\u003eThe CD-2812 is built for rectangular duct installations in forced-air zoning systems. Its 28-by-12-inch face size suits common residential trunk or branch duct configurations. The included Belimo 3-wire actuator is compatible with standard zone control boards that output a 3-wire (open-close-common) signal, making integration into existing or new zoning systems straightforward. This damper is suited for Carrier and Bryant duct systems where a rectangular zone damper of this size is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28-inch by 12-inch rectangular blade size fits standard residential and light commercial duct openings\u003c\/li\u003e\n  \u003cli\u003eIncludes Belimo 3-wire actuator for reliable, low-voltage open-close zone control\u003c\/li\u003e\n  \u003cli\u003eCompatible with Carrier and Bryant zoning system configurations\u003c\/li\u003e\n  \u003cli\u003e12-pound assembled weight indicates robust construction suitable for permanent duct installation\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator interface works with most standard zone control boards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Carrier and Bryant rectangular duct zoning systems requiring a 28-inch by 12-inch zone damper with a Belimo 3-wire actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
