402 CFM Inline Duct Fan with Carbon Filter for Grow Tent Airflow

Designed to manage exhaust ventilation in grow tents, hydroponic systems, and small indoor gardening areas, this inline duct fan with carbon filter produces 402 CFM (683 m³/h) of airflow. The fan can cycle air quickly enough at this airflow rate to avoid stagnant air pockets that can cause mold growth, inconsistent temperatures, and poor plant growth in enclosed grow conditions.

The carbon filter component actively reduces odors and airborne particles as air passes through the fan, beyond what raw airflow alone can. This is important, especially for indoor growers who have to deal with strong plant aromas in shared living areas or flats. When combined, the 402 CFM output and filtration function tackle two distinct issues that many simple exhaust fans without filtration cannot address: air circulation and air quality.

EC Pure Copper Motor Rated at 60W for Efficient Operation

An EC pure-copper motor powers the 402 CFM inline duct fan with a carbon filter and draws 60W. This fan provides robust ventilation performance without the increased electrical draw associated with standard motor designs that operate constantly in grow tent setups, since EC motor technology is intrinsically more energy-efficient than standard AC motors at similar airflow output.

In addition to reducing heat accumulation during prolonged operation, the pure copper winding architecture directly addresses a common failure mode in duct fans used for nearly continuous or 24-hour operation, which is typical in indoor growth. Because weaker motors deteriorate more quickly from moisture exposure in the humid, high-airflow conditions characteristic of hydroponic and grow-tent environments, corrosion protection integrated into the motor housing further enhances dependability.

27.3 dB Low-Noise Operation at 3000 RPM

This inline duct fan with carbon filter can operate up to 3000 RPM while maintaining a noise floor as low as 27.3 dB at low speed, which is quiet enough to run overnight in shared living areas, closets, or bedrooms without creating an annoying background hum. Although the low-speed baseline offers consumers a hushed alternative for prolonged or continuous ventilation cycles, noise production increases at higher speed settings.

This is especially important for growers who operate fans on 24-hour timers, as a noisy fan eventually becomes a livability problem rather than just an irritation. Users can switch between quiet and high-output modes as needed since the 3000 RPM motor speed still provides the full 402 CFM airflow rating at higher settings, ensuring low-noise performance without compromising ventilation strength.

10-Speed PWM Controller with 3-Level Circulation Settings

Instead of a simple on/off or single-speed function, this inline duct fan with a carbon filter features a 10-speed PWM controller that lets customers precisely adjust airflow. Without having to update or replace equipment as conditions change, this degree of adjustability enables fine-tuning airflow to match particular grow stages, tent sizes, or seasonal temperature fluctuations.

The fan also has three circulation settings in addition to speed control, intended to reduce the need for frequent manual adjustments across various circumstances. To meet the needs of both hands-on growers and those who want a more hands-off, automated ventilation configuration, the 10-speed controller and 3-level circulation modes work together to provide users with accurate short-term control and easier long-term operation.

410 Pa Air Pressure for Strong Duct Performance

This fan, which has an air pressure rating of 410 Pa, is designed to sustain robust airflow even when moving air through filters, longer duct runs, or numerous bends—conditions that diminish effective airflow in fans with lower pressure ratings. This is especially important for grow tent setups, as ducting frequently needs to go around obstructions or extend a few feet before reaching an exhaust point.

Higher air-pressure ratings prevent the fan from losing effective CFM output as static resistance increases along the duct path. This is a common problem where fans rated for open-air CFM figures perform noticeably worse when installed with carbon filters and entire duct runs attached. Since this specification represents how the fan operates under actual installed conditions, it is a more useful real-world performance indicator for growers than airflow rating alone.

Inline Duct Fan with Carbon Filter Includes Full Install Kit

The fan unit, two clamps, two hanging straps, and an 8-foot double-layer aluminum foil duct are included with this inline duct fan with carbon filter, eliminating the need to find essential installation parts separately. Compared with buying a bare fan unit and assembling the necessary components one at a time, this approach saves growers time and money when setting up a new tent or upgrading an existing exhaust system.

The unit’s dimensions are 12.4 x 9.06 x 8.27 inches, and its net weight of 13.23 pounds (6 kg) makes it easy to attach using the hanging straps that come with it without the need for specialized support systems. Additionally, the integrated aluminum foil duct ensures compatibility from the outset, preventing a common setup problem where fans and ducting are bought separately and result in different diameters or connection types.
