G-Tools 160mm Inline Fan with Temperature Controller800 m³/h
German EBM motor, built-in temperature controller, and 800 m³/h capacity for two-light grow rooms.
Key Features
- 800 m³/h rated airflow - suited to two-light grow rooms
- 160mm inlet/outlet collar for standard ducting
- Integrated temperature controller - no separate unit required
- German-made EBM motor for reliable, long-running performance
- Backward-curved impeller - up to 15% airflow gain over standard fans
- Variable speed output responds to real-time temperature changes
- Handles significant temperature swings between lights-on and lights-off cycles
- Available as a discounted bundle with the Prima K2603 carbon filter
The G-Tools 160mm inline fan combines an 800 m³/h German EBM motor with a factory-fitted temperature controller in one unit. It is the go-to choice for growers running two lights who want automatic climate management without extra wiring or wall-mounted controllers.
At 800 m³/h, this fan is correctly specced for grow rooms operating two HID or LED fixtures. A common mistake is under-sizing extraction - an inadequate fan struggles to clear heat during lights-on periods, stressing plants and reducing yields. This unit handles the load with headroom to spare.
The built-in temperature controller is the key differentiator here. It ramps fan speed up when temperatures rise and backs off during cooler lights-off periods. That means quieter running at night, lower electricity draw overall, and reduced wear on the motor compared with fans running flat-out around the clock.
The backward-curved impeller fitted as standard is worth highlighting. This blade geometry moves more air per watt than a basic forward-curved design - G-Tools quote up to 15% additional airflow from the same motor. In practical terms that means you are getting genuine 800 m³/h rather than a headline figure that relies on ideal test conditions.
For installation, pair this fan with a 160mm carbon filter. The Prima K2603 is available as a bundle at a reduced price and is a natural match in terms of airflow rating. Use acoustic ducting between the fan and filter to keep noise levels down, and position the fan outside the canopy zone so it is drawing hot air away from the lights efficiently.
Grower’s Note: Temperature-controlled fans are most effective when the sensor probe is positioned at canopy height, not near the floor or ceiling. Canopy temperature is what directly affects transpiration and vapour pressure deficit. Mount the probe where your plants are actually growing and you will get far more accurate speed responses throughout the light cycle.
