DUCTURBO 4'' Inline Ventilation Fan, 160 CFM Adjustable Speed Exhaust for Heating, Cooling, Grow Tents

This inline fan features dual jet-type blades, delivering an airflow of 160CFM. It's compact in size but effectively moves air, even when ducts are extended or filters installed. Suitable for continuous operations.
This 4-inch inline fan includes a variable speed controller for adjustable airflow. It uses a brushless EC motor, consuming 20W/h at maximum speed, also reducing noise with speed adjustments. For constant full-speed use, a larger fan is advised for quieter, more efficient operation.
The fan's casing is made of aluminium with a black coating, offering lightweight durability and rust resistance. Unlike plastic fans, the metal casing adds protection. The blades are flame-retardant PBT, maintaining function without warping at high speeds. Durable dual ball NMB bearings extend the fan's lifespan.
Suitable for various uses including intake or exhaust air, heat transfer, subfloor and roof space ventilation, as well as for use in grow tents, pet rooms, and commercial buildings. Compatible with ducting, maintaining performance over distances.
Each fan undergoes quality checks before shipping. Specifications include a duct size of 4", dimensions of 6.26 x 7.24 x 5.91 in., airflow of 160 CFM, noise level of 56.8 dBA, dual ball bearings, and a controller cord length of 16 FT (5 MTR).
