Phresh HyperFan EC Controller

Hold Your Grow Room Temperature and Cut Your Fan's Running Costs

The Phresh HyperFan EC Controller from G.A.S (Global Air Supplies) is a digital EC fan controller built specifically for the Phresh HyperFan and Phresh Silenced HyperFan. Its Reactive Temperature Technology (RTT) holds your target temperature by running the fan at the lowest speed the room actually needs, so you get steady conditions with lower electricity use and less noise.

Key Benefits

• Reactive Temperature Technology (RTT) reacts fast to sudden heat spikes to prevent overheating, then ramps speed up gradually on slow rises for a steadier, more constant temperature
• Set-and-forget temperature control using the Temperature Set dial in Celsius or Fahrenheit
• Adjustable minimum fan speed anywhere from 0 to 100% in 1% increments, so extraction never drops below the level you need
• Clear digital display for accurate at-a-glance readings
• 5m temperature probe included to reach any position in the tent or room
• Lower running costs by only spinning the fan as hard as conditions demand

Fans running flat out and wasting power?

Basic controllers hold a fixed speed regardless of the room, so a fan often runs at full speed when it does not need to, wasting electricity and adding noise. RTT closes that gap by matching fan output to real temperature, keeping the room in range while drawing only the power the job requires.

How to Use

• Position the 5m probe at canopy height, away from lamps and direct airflow
• Set your target temperature on the Temperature Set dial
• Set the minimum fan speed you want maintained, then connect your HyperFan and run
• To drive two fans from one controller, add the G.A.S Y Splitter Cable; pairing a stronger exhaust fan this way keeps the space under negative pressure so odours cannot escape
