Mars Hydro Inline Duct Fan with Thermostat Controller

More about Mars Hydro Inline Duct Fan with Thermostat Controller

The Inline Duct Fan with Thermostat Controller by Mars Hydro uses an EC motor with PWM speed control. Once installed in your setup as an extractor, it pulls warm, humid air out of your grow tent while fresh air enters through the intake. The included controller shows real-time temperature and relative humidity and lets you adjust the fan speed, giving you precise climate control in your grow room!

Automatic temperature and humidity control

In AUTO mode, set high or low temperature and humidity triggers. When the probe detects a limit, the fan gradually speeds up toward your selected maximum speed. As conditions return to the desired range, extraction slows again. The controller also provides 10-speed manual adjustment, a countdown timer, alarms, controller lock, display adjustment, and sensor calibration. Place the probe around plant height for a useful reading. No app is required for the included thermostat controller; these functions can be managed directly from the wired controller.

Choose your Mars Hydro Inline Duct Fan

Choose between the two available sizes based on the airflow requirements of your grow setup.

Mars Hydro 4-inch (10 cm) inline duct fan with thermostat controller

For smaller tents, the Mars Hydro 4-inch inline duct fan with thermostat controller delivers up to 205 CFM, or around 348 m³/h. This makes the 4-inch model well suited to smaller grow tents that require compact but effective extraction. It has a rated power consumption of 27 W ±5% and a published noise level of 26.8 dB(A).

Mars Hydro 6-inch (15 cm) inline duct fan with thermostat controller

Need more airflow? The Mars Hydro 6-inch inline duct fan with thermostat controller reaches 402 CFM, around 682 m³/h. It has a rated power consumption of 62 W ±5% and a published noise level of 32 dB(A). The extra capacity suits larger tents or systems with filters, bends, and longer duct runs.
