ZoneFirst is a leading brand that specializes in zoning systems for heating and cooling. With their innovative solutions, you can have full control over the temperature in each room of your home or office. By utilizing zoning, you have the ability to shut off rooms that are already comfortable or direct air only to the rooms that require it, resulting in efficient energy usage.

One of the key components of zoning systems is a By-Pass Damper, which is necessary to regulate excess air flow when small zones cannot deliver the required amount of air. ZoneFirst offers a By-Pass Sizing Calculator that helps you determine the type of By-Pass Damper you need based on your total system's cubic feet per minute (CFM) and the CFM of your smallest zone. ZoneFirst provides a range of By-Pass Dampers, including SPRD08, SPRD09, SPRD10, SPRD12, SPRD14, SPRD16, RDM18-SPC, and RDM20-SPC.

These dampers are designed to ensure optimal air flow and maintain a comfortable environment in your home or office. With ZoneFirst, you can experience personalized comfort and energy efficiency by effectively controlling your heating and cooling system.
