6 Inch Inline Booster Fan for HVAC Boost

This 6 inch inline booster duct fan delivers 345 CFM airflow at 3300 RPM while drawing only 19.2W. It suits grow rooms, bathrooms, kitchens, workshops, basements and attics where extra air movement is needed. The plastic housing keeps weight low for overhead duct runs. Variable speed control lets you match output to the space.

Installation and Common Issues

The unit mounts directly into 6 inch ducting and uses a standard C13 or C14 connector at 100-240V. Plastic blades and body allow quick removal for cleaning. Most problems arise when the fan is asked to overcome long or restricted duct runs that exceed its 142 Pa static pressure. Ensure the speed controller is wired before the fan to avoid control loss.

Capacity Limits and Headroom

At 32 dBA the fan runs quietly at lower speeds but reaches full output at 345 CFM. The 142 Pa pressure rating handles typical residential duct lengths with a few bends. Beyond that, airflow drops sharply and the motor cannot maintain rated volume. It is not suited for high-resistance filtration or multi-room distribution without additional boosters.
