Proudly manufactured and assembled in the USA.

Guaranteed for 7 years, from date of shipment, against all defects in material or workmanship, provided that the material has been installed and used under normal conditions. This warranty is limited to the repair or replacement of the material.

The CAR3® is constructed of an amorphous thermoplastic resin featuring antimicrobial, anti-static, and flame retardant additives. The CAR3® is UL 2043 safety classified and labeled for flame and smoke generation. The assembly is sized to fit inside standard rigid round ducting, as well as fittings such as take-offs, tees, etc. A lip or flex-type ring seal gasket around the circumference ensures a tight, no-leak fit

Industry exclusive dual-side airflow adjustment dial and CFM indicator allows you to set or change the airflow quickly, in supply or exhaust applications, without removing the CAR3® from the duct.
