EC Pure Copper Motor for Efficient and Durable 4 Inch Inline Duct Fan Performance

With under 25 watts of power consumption, the VEVOR 4 inch inline duct fan's EC pure copper motor delivers strong airflow. Without compromising airflow performance, its energy-efficient design reduces your electricity costs. For extended operating cycles, the motor reaches 3000 RPM to ensure steady airflow throughout your grow tent or indoor horticulture setup.

By actively preventing heat accumulation during extended operation, the EC motor helps prevent internal overheating, which typically shortens fan lifespans. It is built for humid grow tent conditions, thanks to its corrosion-resistant construction. The motor delivers dependable performance and keeps your ventilation system operating at maximum efficiency, whether you run this fan during daytime cycles or overnight.

205 CFM Airflow Capacity for Effective Grow Tent Ventilation

This 4 inch inline duct fan produces enough airflow to effectively ventilate small to medium-sized grow tents, pushing 205 CFM (349 m³/h). It maintains speed while forcing air through carbon filters and ducting at 143 Pa of air pressure. It is an effective option for growers seeking steady air exchange to promote healthy plant growth, thanks to its combination of volume and pressure.

By lowering excessive humidity, eliminating stagnant air pockets that promote mold and pest activity, and replenishing carbon dioxide levels, strong airflow directly affects plant health. The fan keeps the temperature and humidity within the ranges your plants require by moving enough air each minute to circulate through a typical grow tent many times an hour. For a full ventilation loop, combine it with the carbon filter and aluminum foil duct that come with it.

3-Speed Circulation Settings for Flexible Indoor Air Control

With the fan's three circulation settings, you can adjust the airflow intensity to suit your growing environment. While medium and high speeds manage peak heat loads or flowering stages that require more robust air exchange, low speed is best suited for seedling stages or lower ambient temperatures. Changing settings takes only a few seconds and requires no technical expertise or tools.

These predefined circulation levels reduce the need to adjust your ventilation configuration throughout the day manually. The fan maintains a steady output once you adjust it to your surroundings. By eliminating abrupt temperature fluctuations that stress plants and impede growth during crucial stages of development, this consistency helps stabilize the environment inside your grow tent.

10-Speed PWM Controller and Timer for Precise 4 Inch Inline Duct Fan Adjustment

You have fine-grained control over your airflow output thanks to the built-in 10-speed PWM speed controller, which offers more than the three basic circulation modes. To achieve the exact ventilation rate your setup needs, you can step up or down through ten different speed settings. When adjusting conditions for sensitive plants or when the outside temperature changes between seasons, this degree of control is particularly helpful.

The included timer feature further automates your ventilation routine. Configure the fan to run at predetermined intervals that correspond with your humidity control or lighting cycles. By eliminating the need for human intervention throughout each growth cycle, the timer saves you time and ensures your plants receive consistent fresh air on a reliable schedule without disruptions.

27.1 dB Low-Noise Operation for Quiet Extended Ventilation

This 4 inch inline duct fan is among the quieter models in its class, operating at just 27.1 dB at its lowest speed setting. You can run the fan in living rooms, home offices, or bedrooms next to your grow area without creating distracting background noise, since the noise level is lower than typical conversation. Although speed affects noise level, low and medium settings remain quiet.

During overnight ventilation, when steady airflow is still required but loud mechanical noise is intolerable, quiet operation becomes especially crucial. This fan can run for extended periods at night without interfering with sleep or attracting unwarranted attention. The ability to maintain full ventilation without compromising the comfort of the surrounding environment is important for growers operating their setups in residences or communal spaces.

Complete Kit with Carbon Filter and Aluminum Foil Duct for Odor-Free Air

VEVOR ships this fan as a ready-to-install kit that includes the fan unit, a carbon filter, two clamps, two hanging straps, and an 8-foot double-layered aluminum foil duct. There is no need to find matching parts separately because everything you need to set up a working ventilation loop comes in one kit. Time and uncertainty in matching filter sizes to duct widths are both reduced by the kit format.

The carbon filter keeps the surrounding area fresh and inconspicuous by capturing odor-causing particles before the air leaves your grow room. When installed in confined or uneven areas, the double-layer aluminum foil duct offers flexibility and durability. Without extra hardware, you can install the fan inside your tent at the desired height with the hanging straps. Both novice growers and seasoned hydroponic operators will find the initial setup simple with this comprehensive bundle.
