MRCOOL Signature Down Flow Kit For 3 to 5 Ton Air Handler

Complete your MRCOOL® air handler installation with the Signature Down Flow Kit, specially designed for 3 to 5 Ton MRCOOL Air Handlers.

This kit is essential for configuring your system in a downflow setup, where air is distributed downward through floor ducts. It ensures safe, efficient airflow direction and helps maintain the overall performance and longevity of your HVAC system.

Built to match MRCOOL’s high standards, this downflow kit is durable, easy to install, and perfectly compatible with larger Signature Series air handler units. It’s ideal for residential installations that require airflow to move from the top of the unit downward, such as in homes with basement or crawl space ductwork.
