Sold under the Aprilaire brand, this actuator is a direct replacement component used to control airflow through zone dampers. In a zoning system, actuators open and close dampers to direct conditioned air to specific areas of a building. A normally open actuator means the damper defaults to the open position when the actuator is not energized, allowing airflow to pass through without power. This is a common and important safety configuration in many zoning setups, ensuring that conditioned air continues to flow even during a power interruption. HVAC technicians rely on replacement actuators like the 6998 to restore proper zone control when an original actuator fails. Symptoms of a failing actuator include a damper that will not open or close, uneven temperatures across zones, or a zone that receives no airflow. The 6998 operates at 24 VAC, which is the standard low-voltage control signal used in most residential and light commercial HVAC systems. It runs on single-phase power at 60 Hz, making it compatible with standard North American electrical systems. This unit is manufactured in the USA and does not require Prop 65 labeling. With compact dimensions of 8 inches in length, 6 inches in width, and 5 inches in height, and a weight of 1.25 pounds, the 6998 is a manageable component for service technicians working in tight mechanical spaces. Keeping this replacement actuator on hand reduces system downtime and helps restore zone comfort quickly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNormally open (N.O.) configuration allows default airflow when the actuator is not energized\u003c\/li\u003e\n\u003cli\u003eOperates at 24 VAC single-phase 60 Hz for compatibility with standard residential and commercial HVAC controls\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight design at 1.25 pounds for easy installation in zone damper applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Research Products 6998 replacement actuator restores reliable zone damper control in Aprilaire zoning systems.
