Tornado Pro EC Variable Speed Box Fan

Tornado Pro EC Variable Speed Box Fan

The Tornado Pro EC Variable Speed Box Fan is a powerful, energy-efficient extraction fan designed for larger grow rooms and ventilation systems where high airflow and precise speed control are essential.

Featuring an advanced EC (Electronically Commutated) motor, the Tornado Pro delivers a maximum stated airflow of 4250 m³/h, while offering lower energy consumption compared with traditional AC motor fans.

Its robust yet lightweight construction, integrated mounting brackets and dual-size ducting connections make it a versatile choice for demanding ventilation setups.

Key Features

• Energy-efficient EC motor: Designed to reduce electricity consumption compared with conventional AC fans.
• Variable speed control: Adjust airflow to suit your ventilation requirements.
• Multiple speed settings: Preset airflow levels of 2500, 3250 and 4250 m³/h, plus a boost function.
• Quieter operation: Smooth EC motor speed adjustment helps minimise unwanted vibration and motor noise.
• Dual-size ducting connection: Stepped flanges accommodate 250 mm (10") and 315 mm (12") ducting.
• Easy installation: Lightweight construction with integrated handles and metal mounting brackets.
• External controller compatibility: Supports compatible EC controllers using a 3.5 mm jack connection.
• Durable construction: Tough housing designed for long-term use.
• 5-metre power cable: Provides flexibility when positioning the fan.

EC Motor Technology

Unlike traditional AC fans, the Tornado Pro uses an electronically commutated (EC) motor, combining efficient motor technology with precise electronic speed control.

This offers several advantages:

Lower Running Costs

EC motors are designed to use electricity more efficiently, particularly when operating at reduced speeds. This can help lower running costs in ventilation systems that operate for extended periods.

Precise Airflow Control

The fan speed can be adjusted to match the extraction requirements of your growing environment, avoiding unnecessary airflow and energy consumption.

Reduced Motor Noise

EC technology allows smooth speed adjustment without the additional humming and vibration often associated with conventional AC fan speed control.

Variable Speed Settings

The Tornado Pro features multiple preset airflow settings, allowing you to adjust extraction performance according to your requirements.

The fan can also be connected to a compatible external EC controller for more flexible speed adjustment.

Technical Specifications

Installation and Ducting

The Tornado Pro has been designed to make installation as straightforward as possible. Its lightweight housing, integrated carrying handles and metal mounting brackets allow the fan to be positioned and securely mounted within a suitable ventilation system.

The stepped ducting flange accommodates both 250 mm (10") and 315 mm (12") ducting, providing flexibility when connecting to existing extraction equipment.

For best performance:

• Use appropriately sized ducting and secure it with jubilee clips or fast clamps.
• Keep ducting runs as straight and short as practical.
• Avoid sharp bends, kinks and unnecessary restrictions that can reduce airflow.
• Ensure all ducting connections are securely sealed to prevent air leaks.
• Mount the fan securely to minimise unwanted vibration.

Correct installation helps maintain airflow efficiency and reduces noise caused by air turbulence.

Suitable Applications

With its high extraction capacity and adjustable speed settings, the Tornado Pro EC Box Fan is particularly suited to larger indoor growing environments, commercial horticultural spaces and ventilation systems requiring substantial air movement.

Its combination of powerful extraction, efficient operation and flexible ducting connections makes it a practical option where ventilation requirements may change throughout the year.
