GAMMA EC SUPPLY SERIES

ROOF MOUNTED FANS

D-34

The Gamma EC Series of centrifugal supply air roof units can be

used for supplying fresh air to an air handling unit or to an air

conditioning system. They incorporate the latest state of the art,

energy saving EC motor technology and are most efficient

where conditions vary during the course of the day.

They feature integrated infinitely variable speed control and

eliminate the need for external VSDs, current overloads and

motor phase protection.

The Gamma EC Supply Series is a simple "plug and play"

system which means installers do not need to have specialised

control programming 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 fitted with bird mesh which prevents objects entering

building or interrupting motor operation and are available in 315,

355, 450, 560 and 630mm fan sizes.

Typical Applications

Ideal for supplying fresh air to an air handling unit

or to an air conditioning system. Also suitable where make-up

air or positive pressure is required in the ventilated space.

Features

O

EC motor features reverse polarity protection, locked rotor

protection and soft start.

O

No additional protection such as contactors are required.

O

All motor sizes can be pre-configured to suit specific

sensors and specific 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

Corrosion-proof, robust construction.

O

High performance backward-curved centrifugal impellers

fitted.

O

Can be mounted at angles up to 30°.

Construction

Cowls are of UV-stabilised plastic.

Steel components have a corrosion resistant finish.

Impellers are backward-curved centrifugal design and are of

high performance composite material.

Bird-mesh guards are fitted as standard.

Shutters cannot be fitted.

Motors

Type - electronic commutated (EC) motor.

Electricity supply - 200-277V single-phase, 50/60Hz for 315 to

450mm sizes.

- 380-480V three-phase, 50/60Hz for 560

and 630mm sizes.

Bearings - sealed-for-life, ball.

Integrated EC Controller providing infinite speed control.

Internal Thermal Protection

Integral thermal overload protection is supplied as standard.

Testing

Air flow tests to ISO 5801: 2007.

Noise tests to ISO 3744:2010.

Special Note

All Gamma EC supply 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.
