Twin Gamma Ultra EC Vert – TGUEEC28
Performance Curve - TGUEEC28
Description
The Twin Gamma Ultra EC Series of Mixed-Flow roof fans
have been designed for use in commercial ducted exhaust
applications. Incorporating twin vertical discharge fans, the unit
provides 100% stand-by capacity.
These compact and low profile units are fitted with bird-mesh
to prevent the entry of birds and vermin into the ducting
or building.
Features
- EC motor features reverse polarity protection, locked rotor protection and soft start.
- No additional protection such as contactors are required.
- All models supplied standard with 0-10V control input.
- Can be run as an independent ventilation source or integrated into most building management systems.
- Can be mounted at angles up to 30°.
- Backdraft-shutters are an optional extra (See special note).
Note: Pressure loss across the shutter is now included
in the performance curves.
Construction
Cowls are UV-stabilised plastic.
Impellers are Mixed-Flow design and made from high
performance injection moulded composite material.
Steel components have a corrosion resistant finish.
Bird-mesh guards are fitted as standard.
Motors
Type - electronic commutated (EC) motor.
Electricity supply
- 200-277V single-phase, 50/60Hz.
Bearings - sealed-for-life, ball.
Integrated EC-Controller providing infinite speed control.
Internal Thermal Protection
Thermal protection is supplied as standard on all motors
Testing
Air flow tests based on ISO5801
Noise tests based on ISO13347-3
Special Note
Backdraft shutters are offered as an optional extra, but are
essential to prevent short circuiting and ensuring proper
performance of the product. Due to this, the backdraft
shutter effect on the products performance is included in the
performance curves. This is to ensure accurate selections to
allow reliable and predictable on-site performance. There is no
longer a need to add losses due to the backdraft shutter as
is required with single Gamma models.
Suggested Specification

vertical exhaust type as designed and manufactured by
Fantech Pty. Ltd. They shall provide dual fan vertical discharge
to provide a 100% stand-by capacity and be of the model
numbers shown on the schedule/drawing.
Impellers shall be made from high performance injection
moulded composite material. They shall be Mixed-Flow design
and driven by EC external rotor motors with integrated EC Controller and integral thermal overload protection.
The windband shall be of the vertical exhaust design and
formed from plastic. Steel components shall be corrosion
protected.
All performance data shall be for a complete assembled unit
based on ISO5801 for air flow and ISO13347-3 for noise.
