Control Freak Intelligent Digital Single Fan Controller with Probe

£49.99 incl. Vat
The Control Freak Intelligent Fan Controller could not be easier to use, with its ’Plug & Play’ design and two modes of operation. You can use it as a manual fan speed controller or use an additional 5m temperature probe to operate the unit as a fully automatic speed controller. The probe allows you to use a bespoke software system and gives 50 different speed settings to maintain your grow room. This controller has smooth speed control, giving a more accurate and a quieter operation. The temperature adjustment when using the probe his highly accurate with an adjustment of +/- 1°C. Directions of use: Without temperature probe:
  • Plug the fan into the controller and set the minimum fan speed.
  • Plug the controller in a socket and turn on.
With temperature probe:
  • Plug the fan into the controller and set the minimum fan speed.
  • Plug the temperature probe into the controller and set desired room temperature.
  • Place the sensor in the centre of the grow room – never in direct airflow of the fan.
  • Plug the controller into a socket and turn on.
When switched on, the controller and sensor will scan the room. Once complete, the fan will run at the required speed to maintain grow room temperatures, adjusting when necessary.

G.A.S Balancer for Systemair EC Fan Controllers and Fans

£79.99 incl. Vat

RAM AIR-PRO II Intelligent and Silent Indoor Climate Fan Controller

£109.50 incl. Vat
The RAM AIR-PRO II is an intelligent and silent indoor climate controller designed to control two inline/exhaust fans thermostatically, monitoring and keeping the desired room temperature and air pressure. All you have to do is plug in your fans, set the required air temperature and fan speed/balance and the AIR-PRO will do the rest, maintaining a continuous room temperature in your room and giving you full control over negative pressure. The AIR-PRO II features a remote thermostat sensor and temperature setting, as well as twin fan speed control. This intelligent fan speed controller learns your optimum speed for the temperature/pressure that you desire. The unique software will automatically calculate the running speed for your fans and learn from this to modulate them (ramp down) to a single running speed that maintains the required temperature that you have set. A remote probe is fitted, accurate to within +/- 1 degree, that can be placed in the key temperature sensitive area. The RAM AIR-PRO II looks for a stable fan speed to maintain the desired temperature. This means that your fans will be running below the maximum operating speed. They will be operating at maximum efficiency in reference to power vs. performance, extending fan motor life, whilst only using the minimum electricity required. TIP: For best results, use the AIR-PRO Fan Speed Controller with RAM Inline Fans 100mm go 315mm, however it can be used with other brands to the equivalent size. DO NOT exceed maximum load.  Specification:
  • 1 x 2m remote thermostat sensor
  • Variable temperature control
  • Variable fan speed control
  • Digital display
  • 1 x 2m power lead
  • Up to 7 amps per socket

G.A.S. Digital EC Fan Controller – For Systemair EC Fans Only

£119.95 incl. Vat

Designed specifically for use with Systemair Vector EC fans
A separate Balancer unit is available that will regulate the difference between intake and extractor fans.

The G.A.S. Digital EC Fan Controller is an essential part of a Systemair Revolution Vector EC fan set-up. Together, they represent the most advanced extraction system on the market. Unlike other duct fans, Vectors have been engineered from the ground up for use in the hydroponics industry, after years of intensive research and development. They have ridiculously powerful digital motors and they're very quiet relative to the volume of air they move (though not 'silent' as some would claim). This controller will regulate fans at airflow levels between 1% and 100% with no buzzing or humming, responding to the conditions in the room with pinpoint accuracy. See the video below for more info.

  • No more humming or buzzing sounds!
  • Easily pays for itself by drastically reducing energy costs
  • Ridiculously powerful electronically commutated (EC) motor
  • Plugs directly into Vector EC fans
  • Highly energy efficient system
  • Maintains an optimal grow room climate
  • Precise climate control - regulates fans from 1% output to 100%
  • Features reactive temperature technology
  • Switches between Fahrenheit and Celsius

Save Energy
You use far less power at a slower speed - your power use drops by as much as your fan speed. So when running fans 50% slower, you use 50% less power. Most fan controllers use way more power than this!

90 Speed Settings

You get 90 speeds from 10% - 100%! It’s easier to reach your target temperature and fans run smoothly! 

Connect Multiple Fans

Your controller has two sockets. Use it to run an extractor fan and intake fan from one controller. You can even use an extension lead for multiple intake fans. Just make sure you stay within the amp rating!

Bandwidth Control

Your bandwidth is how much your temperature can rise above your minimum.

Use a tight bandwidth to keep your temperature closer to your target. Or set a wider bandwidth to keep your fans moving smoothly. 

Easy To Use & Set Up

Everything’s plug and play, and you have a large LCD display!
