AC Infinity RAXIAL S4, Inline Booster Duct Fan 4” with Speed Controller - Low Noise HVAC Blower for Basements, Bathrooms, Kitchens, Workshops

AC Infinity is a technology company that specializes in environmental controls for audio/video and HVAC. The company was founded on the principle of working closely with customers to develop great products. Dependable service and a commitment to product quality are the foundations of the business's values.

The RAXIAL Series is a line of duct fans designed to be set in between or at the ends of ductwork to increase airflow in existing HVAC projects like grow tents and other ventilation setups. These booster fans boast a matte black aesthetic that expresses the heavy-gauge construction and high quality. The galvanized steel body has no folded seams, enabling the fan to perform with low noise and no rattling. It also features crimped ridges on the exhaust end for a tight, secure grip on your flex or rigid ducting.

All RAXIAL models include a speed controller to optimize airflow and noise. The soft rotating knob provides ease of use and quick responses to changing conditions. These fans use an AC motor that spins smoothly and relatively silent, capable of high airflow boosting in applications like active intake for grow tents. Featuring a 67,000-hour lifespan, the RAXIAL fans use balanced steel blades and lubricated ball bearings that eliminate the need for regular maintenance.

The AIRTAP, AIRTITAN, AIRBLAZE, and AIRLIFT Series are also inline fans designed for duct boosting to improve airflow in heating and air conditioning applications, and to ventilate home rooms like attics, workshops, bathrooms, and kitchens. Each fan uses an easy-to-use knob controller that adjusts fan speed for specific airflow-boosting needs. These fans feature a unibody framework that helps reduce vibration and ensures smooth and low-resistant airflow.

The RAXIAL S4, S6, and S8 models offer inline booster fans in 4", 6", and 8" duct sizes, respectively. The S4 model can deliver up to 106 CFM and 28 dBA in noise, the S6 up to 265 CFM and 35 dBA, and the S8 up to 428 CFM and 43 dBA. All RAXIAL models include a variable inline speed controller with LOW/MID/HIGH thresholds and an easy on & off switch.

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