Eliminate Bypass Duct Work

Eliminate Bypass Duct Work

N/A Used with the eWD2 and eWD3 zoning panels, the A80-MOC can be used to bypass excess air flow by opening just enough to maintain the minimum airflow and eliminate the need for bypass ducts and a barometric dampers.

Adjustable Close Limit

Adjustable Close Limit

N/A The Close position can be set or limited using the internal cam. Simply loosen the screw and rotate the red cam CW and tighten screw. Minimum close position can be used to insure some air flow even when damper is closed.
