AC Infinity Raxial S8 Inline Booster Duct Fan with Speed Controller, 8"

An inline fan for duct boosting designed to improve airflow in heating and air conditioning applications.

• A duct fan designed to boost airflow in HVAC systems and ventilate home spaces like attics and workshops.
• Features a variable fan speed controller, enabling you to optimize airflow and noise level for any application.
• Unibody die-cast construction with no welded seams; reduces vibration while ensuring smoother airflow.
• AC brushless motor with steel blades and lubricated bearings; not suitable for restricted airflow applications.

An inline fan for duct boosting designed to improve airflow in heating and air conditioning applications, and ventilate home rooms like attics, workshops, bathrooms, and kitchens. Each fan uses an easy-to-use knob controller that adjusts fan speed for your specific airflow boosting needs. It features a unibody framework that helps reduce vibration and ensures smooth and low-resistance airflow. The matte black steel cylinder is fluted and ridged for easy and secure installation in-between ducting. Its balanced steel blades have a 67,000-hour lifespan and spin using permanently lubricated dual-ball bearings to eliminate regular maintenance. The dual ball bearings also allow this fan system to be mounted horizontally or vertically. This kit includes one AC-powered inline booster duct fan, a speed controller with a power plug, mounting screws, and a cable management set.

Speed Controller

The inline variable speed controller can control the fan's speed and turn it on or off. Turning the knob will increase or decrease the fan speed and optimize airflow and noise levels for your application. Its speed range includes a low, medium and high threshold, producing up to 106 CFM and 28 dBA in noise. This speed controller uses a female aviation plug with a metal retainer, tightly securing its connection to the booster duct fan.

Applications

This versatile inline booster fan is made to be installed between ducting for various applications that need improved air delivery. In households, it boosts airflow from HVAC units to remove stale air and odor, ventilating attics, workshops, kitchens, basements etc. In grow tents, grow rooms, and indoor gardens, it's primarily used as an intake fan to bring in fresh air. Please note that this booster fan cannot be used standalone in high static pressure applications like room ventilation. Additionally, it is not suitable for use in applications with restricted airflow, like systems that use carbon filters. For higher performance, see the CLOUDLINE Series.

Frequently Asked Questions

Q: What is the airflow capacity of the AC Infinity Raxial S8 inline booster fan?
A: The AC Infinity Raxial S8 delivers up to 428 CFM of airflow, making it one of the most capable 8-inch inline booster fans available. It operates at 43 dBA noise level and runs on 110-120V AC power at 46 watts.

Q: Can I use the Raxial S8 in a grow tent or grow room?
A: Yes — the Raxial S8 is widely used in grow tents and indoor gardens as an intake fan to bring in fresh air. However, it is not designed for high static pressure applications and should not be used with carbon filters. For carbon filter setups, the AC Infinity CLOUDLINE series is recommended.

Q: How long do the fan blades last and does it require maintenance?
A: The Raxial S8 features permanently lubricated dual-ball bearings with an L10 life expectancy of 67,000 hours — roughly 7+ years of continuous operation. No regular bearing maintenance is required.

Q: Can the Raxial S8 be mounted vertically or horizontally?
A: Yes. The dual-ball bearing motor design allows the fan to be mounted in any orientation — horizontally or vertically — without affecting performance or longevity. The fluted steel cylinder also makes duct installation straightforward and secure.
