Why Buy From Grow Tents Depot
  • Fan/Duct/Filter Specifications: Designed with a 4 Inch size. It ensures impressive airflow up to 205CFM and operates quietly with a 26.8dBA sound level. The fan also comes with a smart controller type that allows for innovative Phone APP Control.
  • Introducing the Mars Hydro 4'' Smart Inline Duct Fan: This model features a 4" inline fan with an airflow capacity of 205CFM. The fan additionally includes a smart core controlled by OTA (over-the-air) data flow. As a result, this improves the ease of managing your space's climate data intelligently.
  • Powerful and Silent Inline Duct Fan: The Mars Hydro iFresh 4-inch inline fan uses a combined-flow design and a PWM-managed EC motor. This enables it to produce up to 205 CFM of airflow with minimal sound interference. With this, the fan becomes an ideal choice for ventilating and cooling grow spaces of various sizes, including 2x2 feet, 2.3x2.3 feet, and 3x3 feet.
  • Smart Ventilation For Indoor Gardens: By downloading the Mars Hydro APP and connecting to the 4-inch inline duct fan, users can enjoy OTA remote control and smart features. These include alarms, climate triggers, and loop timers that can be managed easily via their smartphones. Users can also conveniently regulate fan speed and control on/off timing.
  • Real-Time Environment Data Monitoring: The 6-inch inline fan model comes with a probe sensor that helps display crucial climate data - temperature and relative humidity - in real-time on the APP screen. This provides users with a clear and comprehensive view of the fan speed (RPM) and airflow (CFM) when the duct fan is in operation.
  • Loop Timing Schedule: The Mars Hydro iFresh 4" inline fan also supports automated operation with preset timing and duration. Once set, the fan will automatically start and complete its task each day at the specified time and duration. The fan speed will maintain the pre-set speed all through the operation time.
  • Climate Triggers: By setting a "safe range" for temperature and humidity, the inline fan will maximize its speed whenever the climate data fall outside this range. This feature helps maintain an optimal climate in the grow room or space at all times.
  • Alarms & Notifications: The iFresh smart inline fan is designed to promptly notify the user whenever it detects abnormal behavior or pulls any of the "triggers" you have set. This ensures the user stays updated about the conditions within the grow space.

    Great fan

    This is a great little inline fan that seems to have some power and is perfect for a 3x3 space. It has a high air exchange rate and the fan can be remotely controlled on the App, which is very convenient -! Super convenient and easy to use, it's a great addition to your space!
