Gamma Ultra EC - Vertical – GUDEC56V
Performance Curve - GUDEC56V
Description
The Gamma Ultra EC Series of Mixed-Flow roof mounted exhaust fans incorporates 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 Gamma Ultra 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.
Models come in vertical discharge configurations and are available in 280-630mm fan sizes
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.
- Diameter sizes 400mm and above can be pre-configured to suit specific sensors and specific applications.
- A full range of sensors are available including differential pressure, humidity, temperature, air velocity and pollutant.
- Can be run as an independent ventilation source or integrated into most building management systems.
- Robust and lightweight construction.
- Compact, low profile design.
- Designed for downflow or vertical exhaust applications.
- Can be mounted at angles up to 30°.
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 to both downflow and vertical exhaust models
Motors
Type - electronic commutated (EC) motor.
Electricity supply
- 200-277V single-phase, 50/60Hz for 280 to 450mm sizes.
- 380-480V three-phase, 50/60Hz for 500, 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 based on ISO 5801
Noise tests based on ISO 13347-3
Special Note
Diameter sizes from 400mm 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.
