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.\u003c\/p\u003e\n\u003ch4\u003eSpeed Controller\u003c\/h4\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eApplications\u003c\/h4\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4 class=\"text-center\"\u003eAC Infinity S Series Inline Booster Fan Specs\u003c\/h4\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-12 col-sm-12 col-md-12 col-l-12 col-xl-12\"\u003e\n\u003cdiv class=\"row justify-content-center\"\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\n\u003ctable class=\"table custom-spec-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003cth\u003eAC-RXS4\u003c\/th\u003e\n\u003cth\u003eAC-RXS6\u003c\/th\u003e\n\u003cth\u003eAC-RXS8\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\"\u003e110-120V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 Watts\u003c\/td\u003e\n\u003ctd\u003e37 Watts\u003c\/td\u003e\n\u003ctd\u003e46 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.15A\u003c\/td\u003e\n\u003ctd\u003e0.68A\u003c\/td\u003e\n\u003ctd\u003e0.80A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAir Volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e106 CFM\u003c\/td\u003e\n\u003ctd\u003e265 CFM\u003c\/td\u003e\n\u003ctd\u003e428 CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Humidity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\"\u003e35 to 85% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\"\u003e40 to 140°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNoise Level\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e28 dBA\u003c\/td\u003e\n\u003ctd\u003e35 dBA\u003c\/td\u003e\n\u003ctd\u003e43 dBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStatic Pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.90 mm-H20\u003c\/td\u003e\n\u003ctd\u003e7.65 mm-H20\u003c\/td\u003e\n\u003ctd\u003e2.45 mm-H20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eL10 Life Expectancy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\"\u003e67,000 Hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\"\u003e2 Year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the airflow capacity of the AC Infinity Raxial S8 inline booster fan?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use the Raxial S8 in a grow tent or grow room?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How long do the fan blades last and does it require maintenance?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the Raxial S8 be mounted vertically or horizontally?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
