• The Rebel Applied fan array can be sized to oer
redundant operation in the event of a fan failure
• Each fan communicates to via Modbus
®
and speed, and
alarm are reported through the MicroTech 4 controller. In
the event of a fan failure, the other fans can be sped up
to keep the rooftop unit operational
• Optional backdraft dampers are available on the supply
fan array to prevent recirculation during a fan failure
