Ideal inline ventilation for small spaces

The AUTO-VOX 4 inch inline exhaust fan delivers 130 CFM of airflow for grow tents, bathrooms, basements, kitchens, attics and workshops. Its compact blower design suits wall-mounted installation where ducting space is limited. Home gardeners and DIY builders get effective air exchange without bulky hardware.

EC motor with stepless speed control

The upgraded EC motor provides high efficiency and extended service life while drawing 40 amps. A stepless speed regulator lets you adjust fan speed precisely to match ventilation demand. Stall protection and a wide-voltage power adapter add operational safety.

Quiet 26dB operation in normal use

At 26dB the fan runs quietly enough for living areas and sleeping quarters. ABS plastic housing with PBT blades resists deformation during continuous duty. Low energy consumption keeps running costs down while maintaining consistent exhaust performance.
