Overview
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. Models come in downflow or vertical discharge configurations and are available in 250, 315, 355, 450, 560 and 630mm fan sizes.

Features and Benefits
Design
The Gamma EC Series is a simple “plug and play” system which means installers do not need to have specialised control programing knowledge.
Sensors
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.
Downflow Exhaust Series
Impellers are made from high performance composite material. They are backward-curved centrifugal and driven by EC external rotor motors with integrated EC Controller and integral thermal overload protection. Diameter sizes from 315mm and above are pre-configured to suit the selected sensors and the required applications. The cowls are downflow exhaust design and manufactured from UV-stabilised plastic. Steel components are corrosion protected.
Vertical Exhaust Series
Impellers are made from high performance composite material. They are backward-curved centrifugal and driven by EC external rotor motors with integrated EC Controller and integral thermal overload protection. Diameter sizes from 315mm and are pre-configured to suit the selected sensors and the required applications. The windband is of a vertical exhaust design and manufactured from UV-stabilised plastic. Steel components are corrosion protected.
Specification
Construction
Cowls are UV-stabilised plastic.
Impellers are backward-curved centrifugal design and are of high performance composite material. Steel components have a corrosion resistant finish. Bird-mesh guards are fitted as standard.
Motor
The fans are built with electronic commutated (EC) motor with sealed for life ball bearings. The motor requires an electricity supply of 200-277V single-phase, 50/60Hz for 250 to 450mm sizes. Electricity supply of 380-480V three-phase, 50/60Hz is required for 560 and 630mm sizes.
Control
Integrated EC-Controller providing infinite speed control.
Additional Information
Diameter sizes from 315mm and above can be pre-configured to suit specific sensors and specific applications. Please advise Elta Fans of these parameters at the time of order. EC motors should be directly connected to their appropriate AC supply. EC motors should not be regularly power cycled.
Protection
Integral thermal overload protection is supplied as standard.
Testing
All units are tested to ISO 5801:2007 (airside performance) and ISO 3744:2010 (sound performance).
