WHAT IS BYPASS?
A bypass system consists of a short duct connecting the supply plenum to the return air plenum. A “bypass” damper is installed in this duct that opens/closes automatically to maintain constant pressure inside the supply air duct when zones open and close. When the correct size bypass damper is installed and adjusted properly, it will be fully CLOSED when all zones are calling (no air bypassing) and will OPEN proportionately as zone dampers close.

THE ECOJAY MODULATING BYPASS DAMPER INCLUDES THE STANDARD POWER DAMPER WITH A PRE-WIRED STATIC PRESSURE SWITCH. MODULATING (STATIC PRESSURE CONTROLLED) BYPASS DAMPERS SHOULD BE USED WHERE RELIABILITY AND QUIET OPERATION ARE NEEDED. THIS METHOD PROVIDES THE MOST ACCURATE AND EFFICIENT VERSION OF PRESSURE RELIEF IN THE SUPPLY DUCT FOR ANY ZONING SYSTEM. ASSEMBLED IN THE USA.
