The GL Gamma EC Series of centrifugal roof mounted exhaust fans incorporate 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 compact and low profile GL 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.
They are suited to ducted vertical exhaust applications, include a removable windband that provides easy access for cleaning and maintenance, and are available in 315, 355, 450, 560 and 630mm fan sizes.

Features

EC motor features reverse polarity protection, locked rotor protection and soft start.

No additional protection such as contactors are required.

Can be pre-configured to suit specific sensors and applications, and are supplied standard with 0-10V control input.

A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.

Can be run as an independent ventilation source or integrated into most building management systems.

Robust, galvanised steel housing and cowl.

Quick release toggle clamps provide easy access for cleaning and maintenance.

Can be mounted at angles up to 30°.
