HOW TO ORDER
SUGGESTED SPECIFICATIONS
The roof ventilators shall be of the GL Gamma EC Series vertical
discharge type as designed and manufactured by Fantech Pty
Ltd and be of the model numbers shown on the
schedule/drawings. Impellers shall be made from high
performance composite material. They shall be of backward-
curved centrifugal design and driven by EC external rotor motors
with integrated EC Controller and integral thermal overload
protection. They shall be pre-configured to suit the selected
sensors and the required applications.
The cowl shall be of the vertical discharge design and
manufactured from galvanised steel. Steel components shall be
corrosion protected.
The windband shall incorporate quick-release toggle clamps to
provide easy access for cleaning and maintenance.
All models shall be fully tested as a complete assembled unit to
ISO5801:2007 for air flow and ISO 3744:2010 for noise.

Special notes
Backdraft shutters are an optional extra refer to page
J-2
for
details. The pressure loss across the shutter has to be added to
the system pressure before making selections.
All GL Gamma EC models can be pre-configured to suit specific
sensors and specific applications. Please advise Fantech
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.

DESCRIPTION
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.
Typical Applications
Can exhaust clean air and a range of toxic and noxious gases
from a wide range of commercial and industrial applications.
Ideal for applications requiring an all metal construction and
where the amount of air required varies according to demand.
Features
O
EC motor features reverse polarity protection, locked rotor
protection and soft start.
O
No additional protection such as contactors are required.
O
Can be pre-configured to suit specific sensors and
applications, and are supplied standard with 0-10V control
input.
O
A full range of sensors are available including differential
pressure, humidity, temperature, air velocity and pollutant.
O
Can be run as an independent ventilation source or
integrated into most building management systems.
O
Robust, galvanised steel housing and cowl.
O
Quick release toggle clamps provide easy access
for cleaning and maintenance.
O
Can be mounted at angles up to 30°.
Construction
Cowls are of galvanised steel construction.
