Vents - TT 150 Un Mixed-Flow Inline Fan Ø150 mm with Controller and Sensor

150 mm inline fan with a mixed-flow impeller, built-in speed controller and temperature sensor. Moves up to 520 m³ per hour at 44 dB(A) at three metres and weighs 3.19 kg.

The TT 150 Un is the largest size of Vents' standard TT series and made for air up to 60 °C. The difference with the regular TT 150 is the control: this fan adjusts itself to the temperature.

Controller with temperature sensor

The Un version has a speed controller with an electronic thermostat built into the housing and a separate temperature sensor on a 4 metre cable. Place the sensor where it matters, for example at the top of the grow room. Use the knobs on the fan to set the base speed and the target temperature. When it gets warmer than set, the fan switches to full power. When the temperature drops again, it returns to the set speed. So you don't need a separate controller or thermostat.

The fan comes with cable and plug: connect it, hang the sensor and set it up.

Construction and maintenance

The housing is plastic, the motor runs on ball bearings and the fan is IPX4, so splash-proof. It can be mounted in any position. The motor section with impeller comes out of the housing without disconnecting the ducts. Clean the impeller at every crop change: dust costs airflow and causes imbalance.

Frequently asked questions

What is the difference with the TT 150?
The regular TT 150 has no control on board and no plug. The TT 150 RV has a switch for low and high. The Un controls steplessly and switches by temperature itself. Motor, airflow and housing are the same.

Where do I hang the sensor?
Where you want to monitor the temperature, usually at the top of the room where heat builds up. Not directly in the fan's airflow or under a lamp.
