VEVOR Inline Duct Fan, 807 CFM 8 inch EC Motor Ventilation Fan with 3-Speed Circulation, 10-Speed PWM Controller, Timer-Controlled Operation, Cooling for Grow Tents, Indoor Gardening, Hydroponics

Delivers 807 CFM of Airflow for an 8" Inline Duct Fan

Static air, retained humidity, and odor accumulation that indicate more serious underlying issues are all directly caused by poor ventilation in a grow tent. This 8" inline duct fan can actively move air through a grow tent or small indoor space, with an exhaust output of 807 CFM (1372 m³/h). The fundamental specification that determines whether a duct fan can truly meet a tent's ventilation requirements is the airflow number.

Without the need for a large industrial unit, 807 CFM offers significant exhaust power for hydroponics systems, indoor gardening, or any enclosed grow space where regular air exchange directly affects plant health. This 8" inline duct fan strikes a compromise between actual airflow capacity and a footprint that fits into a grow tent arrangement, making it ideal for small to mid-size indoor exhaust applications.

EC Pure Copper Motor for Efficient, Heat-Resistant Operation

A duct fan's performance during extended continuous operation is determined by its motor quality, and this unit features an EC motor specifically selected for efficiency and heat management. Because pure copper windings conduct heat more effectively than inferior substitutes, the motor can run cooler even during prolonged operation. 

This reduces the risk of heat buildup, which can cause premature motor failure in less expensive fans. In such an unsupervised, continuous-use situation, a motor that is prone to overheating under prolonged load is a true liability. This 8" inline duct fan's EC motor is more heat-resistant, which is crucial for indoor gardening settings where moisture exposure and humidity are regular rather than sporadic.

3-Level Circulation Settings with 10-Speed PWM Control

With three-level circulation ventilation settings and a 10-speed PWM controller, this fan meets the unique airflow requirements of each grow room, which vary based on plant stage, tent size, and ambient conditions. The three-level circulation settings are designed to be quickly adjusted across a variety of common environments, eliminating the need for human fine-tuning each time conditions change slightly.

The 10-speed PWM controller lets you adjust airflow more precisely than the basic circulation presets, providing fine-grained control that is important for gardeners handling delicate plants that respond differently to changes in airflow strength. Another level of ease is added by timer-controlled operation, which eliminates the need for manual on/off management throughout the day and permits scheduled ventilation cycles. When combined, these controls provide this 8" inline duct fan with a degree of versatility that is just not possible with simple single-speed exhaust fans.

Runs as Low as 29.2 dB with 8" Inline Duct Fan 

The low speed makes it quiet enough to run overnight. Noise is a major concern for anyone operating ventilation equipment in a home, apartment, or communal living space. Although the low-speed rating provides a clear foundation for how quiet this unit may operate when full exhaust power isn't required, noise levels do fluctuate with the speed setting, so higher airflow demands will result in noisier operation.

For indoor growers who run ventilation all night, this low-noise performance is especially important because a noisy fan might mean the difference between a livable space and a constant background disturbance. This 8" inline duct fan is useful for prolonged, real-world interior use rather than simply brief daytime bursts since it can operate almost silently during low-demand times while still having the ability to increase airflow when necessary.

164W Rated Power with 660 Pa Air Pressure

The effectiveness of a duct fan in pushing air past resistance, such as bends in the ducting, filters, or longer duct runs, depends on both air pressure and airflow volume. With an air pressure rating of 660 Pa, this device has sufficient force to maintain efficient circulation not only in open, unobstructed situations but also when operating against the ducting resistance typical in actual grow tent setups.

For the airflow and pressure output this fan produces, its rated power demand of 164W is a fair energy cost. The motor can reach its full 807 CFM rating at up to 3200 RPM when demand requires it, and the multi-speed controls allow you to scale power draw down during times of lower demand rather than continuously operating at full RPM regardless of actual ventilation needs.

Compact 11.81 x 9.45 in. Build for Grow Tent Ventilation

There isn't much room in the grow tent, and large equipment takes up space that should be used for plants, not ventilation hardware. The fan measures 11.81 x 9.45 x 9.06 inches (30 x 24 x 23 cm) and weighs 7.23 pounds. This fan is small enough to fit into standard grow tent ventilation setups without taking up much room. 

The unit remains lightweight without compromising structural durability, thanks to the PP construction of the housing and fan blades. It is important to note that this fan ships only as an inline duct fan unit; hanging straps, ventilation ducts, and duct connectors are sold separately and must be purchased in addition to the fan for a full configuration.
