Compact 4 Inch Inline Duct Fans for Indoor Heating, Cooling, and Grow Tents

To ensure optimal indoor air circulation, a reliable ventilator is of the utmost importance. Our cutting-edge inline fan, equipped with an EC motor, offers a superior solution.

The EC motor, featuring a variable speed controller, enables the fan to operate remarkably quietly and reach low speeds without generating excessive noise or heat. Remarkably, this motor is twice as energy-efficient, potentially saving you up to 30% on energy costs over the long run.

Boasting a mixed-flow design, our fans maintain impressive CFM (Cubic Feet per Minute) and high static pressure – a critical factor in fan performance. Unlike some other fans that struggle with back-flow, our duct fan achieves an impressive 334 PA of static pressure at its maximum 5,000 RPM.

The two jet-type blades are designed to create optimum airflow, resulting in higher air pressure, higher airflow, higher efficiency, and greater energy savings. At maximum speed, this fan moves an impressive 160 CFM (275 m³/h) of air.

For added convenience, the fan speed can be easily adjusted within a 0-100% range using the included speed controller. The controller cord is a generous 16 feet (5 meters) long, with 2 TRRS 3.5mm male jacks on both ends.

Engineered for durability, the fan's casing is made of aluminum with a white finish, making it lightweight yet sturdy and rust-resistant. Unlike plastic ventilation fans that are prone to cracking, the metal construction provides reliable protection against accidental damage. The PBT (polybutylene terephthalate) material used for the blades ensures they can revolve smoothly and powerfully at high speeds without deformation, thanks to their high hardness.

This versatile fan can be used for a wide range of applications, including intake or exhaust air, heat transfer, sub-floor ventilation, roof space ventilation, warehouse ventilation, pet room deodorization, and grow tent or hydroponics air circulation. It can also be installed in various indoor locations, such as bathrooms, garages, kitchens, and attics, wherever improved airflow is needed.

For your peace of mind, each fan undergoes rigorous quality control before shipment, and our after-sales service team is available to cater to your needs. The fan's specifications include a 4-inch duct size, dimensions of 6.26 x 7.24 x 5.91 inches, an airflow of 160 CFM, a noise level of 56.8 dBA, dual ball bearings, and a 16-foot (5-meter) controller cord length.

In summary, this DUCTURBO 4-inch inline fan combines compact yet powerful performance, energy efficiency, robust construction, and versatile applications, making it an excellent choice for your ventilation needs.
