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

The roof ventilators shall be of the Twin Gamma Ultra EC Series 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.
