205 CFM Airflow Capacity for Effective Inline Exhaust Fan for Grow Tent Ventilation

This VEVOR inline exhaust fan for grow tents moves 205 CFM (349 m³/h) of air at 350 Pa of standing pressure, so your plants always have fresh air. The 4-inch duct fan works with standard ventilation systems and can meet the airflow needs of small- to medium-sized grow rooms without overheating. This fan keeps air moving and stops smells from building up, whether you have a small closet grow or a room just for hydroponics.

The 3000 RPM motor effectively pushes air through your duct system, making sure that air always flows from the exhaust to the roof. Good airflow prevents hot spots, reduces humidity-related problems like mold, and helps plants grow stronger at all stages. By using this fan to support your ventilation system, you can create a stable environment where your plants can grow without issues. 

Smartphone App and 4 Auto Modes for Smart Climate Management

You can have full control of the VEVOR inline exhaust fan for grow tent from anywhere with an app on your phone. You can check environmental readings, adjust settings, and monitor the current speed without entering your grow space. This remote access is very helpful for growers who manage several tents or need to check in during overnight runs.

The fan has four built-in auto modes that let it adapt to changing conditions without constant user input. You tell the fan what speed it needs to be to stay within those limits. This way, your grow space stays stable even when you are not there. This automation reduces the risk of temperature or humidity drops or spikes that can stress plants and reduce yields during critical growth periods. 

Inline Exhaust Fan for Grow Tent with Quiet 27.1 dB Low Noise Operation

This inline vent fan for grow tents is one of the quieter options for indoor growing, producing only 27.1 dB at low speed. It is good for living rooms, flats, and other places where low noise levels are important because it has a low noise floor. You can leave it running overnight without worrying about the constant hum waking you or drawing attention.

Noise levels drop as speed increases, so you can still turn on full airflow when you need to and keep things whisper-quiet when demand is low. Because it runs with less shaking than most AC motors, the EC motor helps make the profile quiet. With a net weight of only 4.3 pounds and a small 12.01 x 8.27 x 7.28-inch size, this fan is easy to install and will not rattle or resonate through your duct system. 

Temperature and Humidity Sensor for Real Time Environmental Monitoring

The built-in temperature and humidity sensor sends real-time environmental data to the controller and the smartphone app. This way, you can always see the full picture of what is going on in your grow place. You can track trends, spot outliers early, and make adjustments based on accurate information before small issues become serious problems that could destroy crops.

With this sensor integration, many setups do not need a separate environmental monitor. This means you only have to handle fewer devices. This information tells the fan what to do in its automatic modes, making the feedback loop between the environment and airflow reaction stronger. One small unit does everything growers need for precise environmental control without the need to buy expensive, complicated automation systems. 

EC Pure Copper Motor for Durable and Energy Saving Performance

The fan's 25W EC pure copper motor delivers powerful airflow while consuming little energy. This unit has a substantial efficiency advantage over conventional AC motors thanks to EC motor technology, which uses less power while producing a constant output at all speed settings. For growers who operate their ventilation systems continuously, this makes it the perfect option.

Pure copper windings are corrosion-resistant and can withstand the typical heat and humidity levels found inside grow tents without deteriorating over time. In harsh growing conditions, the motor actively controls heat accumulation to avoid thermal stress, which reduces motor lifespan. You receive a dependable, long-lasting fan that endures lengthy cultivation cycles and operates at peak efficiency year after year.

10-Speed PWM Controller for Precise Airflow Adjustment

You can adjust the precise airflow your grow space requires at any point during the growth cycle, thanks to the ten different speed levels provided by the included PWM controller. Mature plants in full bloom require more vigorous circulation than seedlings and clones, and this fan handles both extremes without requiring you to switch equipment. You can better control variations in humidity and temperature by fine-tuning airflow.

By avoiding the efficiency losses and noise spikes associated with earlier voltage-based control techniques, PWM speed control maintains the motor's smooth operation throughout the whole speed range. When the lights are off, you can turn the fan down to minimize noise and power consumption. When the lights are on and heat production is at its highest, you can increase the fan speed. This level of control lets you manage your grow environment proactively rather than reacting to problems after they develop.
