ANCILLARY EQUIPMENT
The Gamma EC Series of centrifugal roof mounted exhaust fans
incorporates the latest state of the art, energy saving EC motor
technology. They feature integrated infinitely variable speed
control and eliminate the need for external VSDs, current
overloads and motor phase protection.
The Gamma EC Series is a simple "plug and play" system which
means installers do not need to have specialised control
programing knowledge.
Matching sensors can easily be connected to monitor the
ambient conditions in a space and provide real time feedback
to the fan. The fan's on-board microprocessor can adjust the
speed and therefore modulate the ventilation rate to match the
specific requirements of the area.
Models come in downflow or vertical discharge configurations
and are available in 250, 315, 355, 450, 560 and 630mm
fan sizes.
Typical Applications
Exhausts air from a wide range of commercial applications such
as factories, warehouses and workshops, change rooms,
bulk goods, retail outlets and assembly halls.
