iO HVAC Controls EB-2812 28 x 12 Heavy Duty Motorized Bypass Damper, replacement for EWC EBD-28X12

iO HVAC Controls EB-2812 EB Series electronic bypass dampers are used to automatically bypass excess air when increases in duct static pressure occur due to closing of zone dampers. The EB series dampers utilize a floating-type motorized actuator along with the iO-SPC-800 static pressure control. The iO-SPC-800 has a fully calibrated setpoint dial for easy set-up and adjustment. The iO-SPC-800 maintains the system static pressure by modulating the bypass damper. EB series electronic bypass dampers are recommended for systems from 0.08" WC up to 1.20" WC of static pressure.
