AC Infinity RAXIAL S6 Inline Booster Duct Fan — 6-inch, 265 CFM, Variable Speed Controller

Overview

The AC Infinity RAXIAL S6 is a compact 6-inch inline booster designed to boost airflow through existing duct runs and to help ventilate spaces like attics, basements, bathrooms, kitchens, and workshops. Its slim profile fits standard 6-inch ducts, making it a versatile addition to both home HVAC setups and specialty ventilation projects. With dimensions of 7.28 x 5.90 x 5.90 inches, it can tuck into crawlspaces, attic chases, or utility closets without taking up valuable floor space while still delivering meaningful airflow along the duct network.

At the heart of the unit is a variable speed controller that lets you tailor performance to the task at hand. You can raise airflow for rapid ventilation when needed or dial it back to keep noise low during quiet hours. This adaptability makes it suitable for a range of environments, from living spaces to work areas where controlled air movement matters.

Key Benefits

• 265 CFM nominal airflow supports steady ventilation through typical 6-inch duct runs.
• Variable speed control enables precise balance between airflow and noise level.
• Unibody die-cast construction minimizes vibration for smoother operation.
• AC brushless motor with steel blades and lubricated bearings aims for reliable, low-maintenance performance.
• 6-inch duct connection with a compact footprint allows flexible installation in tight spaces.

Performance and Versatility

In real-world use, the RAXIAL S6 helps move air through existing ductwork, supporting improved air exchange in basements or attics, reducing humidity in bathrooms, or refreshing air in workshops. The 35 dBA noise figure at typical speeds keeps operation unobtrusive for nearby living areas while you work or relax. The controller’s range lets you optimize for your priorities—whether you value quicker airflow, quieter operation, or a middle ground that suits daily routines.

Designed for environments with ample duct passage, this inline booster is not intended for severely restricted airflow applications. It’s well suited for standard residential duct networks and lighter commercial spaces where flexible, adjustable ventilation is helpful.
