## Description

iFresh 4-Inch Smart Inline Duct Fan with Variable Speed Controller, Temperature and Humidity Probe Sensor - Inline Fan for Heating Cooling Booster, Grow Tents

## Features

- Smart Ventilation For Indoor Grows: Download the Mars Hydro APP to connect to the 6-inch inline duct fan and growers can enjoy OTA remote control and smart features including alarms, climate triggers, loop timers with a few clicks on their smartphone ... Fan speed, and on/off can also be done with your finger.
- Powerful Inline Fan: The Mars Hydro iFresh 4-inch inline fan provides up to 205 CFM of airflow with low noise thanks to its PWM-controlled EC-powered motor and mixed-flow design.
- Real-Time Environment Data Monitor: 4-inch inline fan comes with a probe sensor so key climate data - temperature and relative humidity - can be displayed in real-time on the APP screen, whether you are near your grow unit or not. When the duct fan is operating, growers can get a clear picture of the fan speed (RPM) and airflow (CFM) on the screen.
- Loop Timing Schedule: By setting a start time and duration, the Mars Hydro iFresh 4" inline fan will automatically start working at a preset time each day and complete its task at the end of the duration. Fan speed is the default speed.
- Climate Triggers: Growers can choose another automatic setting - the climate trigger. By setting a "safe range" of temperature and humidity, the inline fan will start working at maximum speed when the temperature or humidity is not within that range. As a result, the optimal climate is always maintained in the grow room.
