Powerful and Quiet Inline Fan

The Mars Hydro iFresh 6-inch inline fan boasts a PWM-controlled EC motor and mixed-flow design, which allows it to provide up to 402 CFM of airflow with low noise. This makes it capable of ventilating and cooling grow tents measuring 4x4 feet and 5x5 feet in size.

Activated Charcoal Carbon Filter

The Mars Hydro carbon filter is crafted using activated charcoal, which effectively eliminates unwanted odors, pungent smells, and particulates from growing tents and rooms. The filter's double-sided steel mesh body provides a 53% open area for airflow, enabling the odor absorption and elimination process to be carried out thoroughly. It's important to note that the carbon filter is covered by a prefilter cloth, which should not be removed during use.

Smart Ventilation For Grow Tent

By downloading the Mars Hydro app, indoor growers can connect to the iFresh 6-inch inline duct fan and enjoy smart features such as OTA remote control, alarms, climate triggers, and loop timers, all of which can be accessed with just a few clicks on their smartphone. Fan speed and on/off functions can also be controlled with a simple touch of a finger. (By the way, growers can also use the speed controller that comes with the fan to control the it)

Remote Real-Time Data Monitor

The Mars Hydro iFresh 6-inch inline fan is equipped with a probe sensor that enables real-time monitoring of key climate data such as temperature and relative humidity on the app screen. This feature can be accessed from anywhere, whether you are near your grow unit or not. When the duct fan is in operation, growers can also easily view the fan speed (RPM) and airflow (CFM) and climate data on the app screen, providing a clear picture of their environment's conditions.

Loop Daily Timing Schedule

With the loop timing schedule feature, growers can set a start time and duration for the Mars Hydro iFresh 6" inline fan to begin working automatically at that time each day and complete its task at the end of the duration.

Automatic Climate Triggers

Using the climate trigger feature, growers have the option to select another automatic setting. By setting a "safe range" of temperature and humidity, the inline fan will automatically operate at maximum speed when the temperature or humidity falls outside of that range. This ensures that the grow room always maintains an optimal climate without frequent adjustment.

Safety Alarms & Notifications

The iFresh smart inline fan is equipped with an alarms and notifications feature that immediately sends alerts to your phone when it detects any suspicious behavior or triggers that you have set. This allows growers to stay informed of any changes happening in the grow room.
