Series Description

The Johnson Controls RA-2000 Series airflow measuring system is equipped with a one-piece ABS plastic flow sensing cross with a 16 inch (406 mm) diameter or less, and a two-piece anodized aluminum extrusion sensing tube with an 18 inch (457 mm) diameter and larger. The RA-2000 Airflow Measuring system is designed to meet industry requirements for a round air measuring system with low leakage and east installation to spiral ductwork. The design of the RA-2000 system incorporates a low leakage control damper with a neoprene seal placed between two round blades. The airfoil sensing tubes sample the air pressure across the full diameter of the duct.
