6" Inline Exhaust Fan for Workshops

The AUTO-VOX 6" inline exhaust fan delivers up to 345 CFM of airflow for grow tents, basements, bathrooms, kitchens, attics and workshops. It suits growers and DIYers who need reliable ventilation in a single duct run. Buyers who require multiple zones or integrated carbon filtration will need a more complex system.

Thermals Noise and Power Draw

The EC motor provides high efficiency with low energy consumption and extended service life. Operation stays at just 32 dB(A) for a peaceful environment. Stall protection and a wide voltage range adapter add safety during continuous use.

Stepless Speed Controller Benefits

The bundled stepless speed regulator lets you match fan speed precisely to the current ventilation demand. This reduces unnecessary noise and power draw when full airflow is not required. ABS housing and PBT blades resist deformation for durable performance.

商品問答

How do I mount the 6" inline fan to the wall and connect ducting without leaks?

Secure the ABS housing to a solid surface with appropriate screws through the mounting flanges, then slide ducting over the 6" spigots and seal each joint with foil tape or worm-drive clamps; the step most often missed is sealing both the intake and exhaust connections so the 345 CFM rating is actually achieved.

What parts of the EC motor fan will need attention after long-term use?

The PBT blades and ABS housing resist deformation, so the only routine task is wiping dust off the blades and checking that the speed controller potentiometer turns smoothly; bearings are sealed in the EC motor and are not user-serviceable.

At what point does the 32 dB(A) noise level rise noticeably during continuous running?

The 32 dB(A) figure is measured at full speed under free-air conditions; restricting ducting, adding a carbon filter or running the stepless controller near maximum static pressure will increase audible turbulence before the motor itself gets louder.
