DESCRIPTION
The Short Case Axial EC Series fans incorporate the latest
state-of-the-art EC motor technology. The range features fully
integrated, infinitely variable speed control which eliminates
the need for external VSDs, current overloads and motor
phase protection. They are an energy saving solution
and are most efficient where conditions vary during the course
of the day.
Optional matching sensors monitor the ambient conditions in a
space and provide real time feedback to the fan. The fan's
on-board microprocessor adjusts the motor speed and therefore
modulates the ventilation rate to match the specific requirements
of the area.
The Short Case Axial EC fans are a simple "plug and play"
system which means installers do not need to have specialised
control programing knowledge. They are available in 7 sizes
ranging from 250 to 630mm diameter.
Typical Applications
Exhausting or supplying air to applications handling clean,
ambient air. Also where automatic air modulation is required.
Features
O
EC motor features reverse polarity protection, locked rotor
protection and soft starting.
O
No additional electrical protection such as contactors
are required.
O
All models supplied standard with 0-10V control input.
O
Diameter sizes 500mm and above can be pre-configured
to suit specific sensors and specific applications.
O
A full range of sensors are available including differential
pressure, temperature, air velocity and pollutant.
O
Can be run as an independent ventilation source or
integrated into most building management systems.
O
Compact, short case design with light-weight but robust
construction.
O
Low noise, high performance impellers with enhanced
aerodynamic design.
O
An electric junction box is fitted as standard.
O
Capable of operating at temperatures up to 60
°
C.
O
Units can be mounted at any angle.

Special Note
Diameter sizes from 500mm and above 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.
SUGGESTED SPECIFICATION

EC Series as designed and manufactured by Fantech Pty Ltd
and be of the model numbers shown on the schedule/drawings.
The axial impellers shall be made from high performance
composite material. They shall be driven by an EC-DC external
rotor motor with integrated EC-Controller and integral thermal
protection. Diameter sizes from 500mm and above shall be
pre-configured to suit the selected sensors and the required
applications. Casings shall be of galvanised steel construction
with a polyester epoxy finish.
All models shall be fully tested to BS848:part 1, 1980 for air flow
and BS848:Part 2, for noise.
