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-resistant 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. 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 can 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 428 CFM and 43 dBA in noise. Applications This versatile inline booster fan is made to be installed in 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 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. RAXIAL Series 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. Premium Solid Steel Body This booster fan boasts a matte black aesthetic that expresses the heavy-gauge construction and its 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 models include a speed controller to optimize airflow and noise. The soft rotating knob provides ease of use and quick responses to changing conditions. High Performance Motor Uses an AC motor that spins smoothly and relatively silent. Capable of high airflow boosting in applications like active intake for grow tents. Long-Lasting Features a 67,000 hour lifespan, using balanced steel blades and lubricated ball bearings that eliminates the need to maintain the fan. Review: Burn out after 3 seconds - Plugged in, switched on, 3 seconds and smoke comes out from the fan. Completely dead, so far had to pay £30 to ship it back, waste of money and time, bad experience. Got a German's made, works great.

Airflow is pretty reasonable coming out of the end and the air is scrubbed good with a clean fresh smell. I'm here because I'm buying a second one to use as an intake fan to complete the setup. I'm only running 1 95 watt light in this tent so I don't need extreme airflow. In my 3x3 flowering tent however, I am running the ac infinity cloudine 4" fan with the ac infinity 4" carbon filter. More lights and more smell equals more airflow needed. These are a little bit on the louder side compared to the cloudine so if that doesn't bother you then you'll be ok. You'll need those running at full speed with the carbon filter. I run my cloudine at half speed. If you're looking to save some money then it will do the job but the cloudine is the one to get otherwise. I'll probably get another cloudine in the future for my veg tent but for now this will be ok. **Q: Will this plug into T8 digital temp and humidity control?** A: I use it in my tent to exhaust air out and have it in a timer, but you can def plug it into an environmental controller. **Q: I need to run at approximately 190 to 200 cfm. Would it be quieter to run a 6 inch at high speed, or an 8 inch at low speed to achieve this flow?** A: Go with the 8 inch which will move more air at lower speeds. Higher speed it becomes a small wind tunnel and is loud.. **Q: can this fan be used on the end of a hose connected to an engine exhaust pipe to help get the exhaust out of my garage?** A: Usually when you are venting a car exhaust you would hook the hose directly onto the tailpipe and then vent it outside. The force of the exhaust would not need a fan. You could put this fan above that area and suck out any air that you do not want. I have mine hooked up basically for the winter time to suck the hot air around my furnace and heat another room in the basement, and it works great. ## Customer Reviews ### ⭐ Burn out after 3 seconds *by L***. on 8 February 2024* Plugged in, switched on, 3 seconds and smoke comes out from the fan.

Germany-USA 1-0 ### ⭐⭐⭐⭐⭐ Fonctionne comme prévu et bien. *by G***N on 18 November 2023* Très bien pour propulser l'air chaud de mon poêle au sous-sol vers le rez-de-chaussée. ### ⭐⭐⭐⭐⭐ Using as an attic ventilator. Low noise/vibration, satisfied with performance. *by D***. on 25 January 2025* This review is for AC Infinity RAXIAL S8, Inline Booster Duct Fan 8” with Speed Controller - Low Noise Inline HVAC Blower Can Fan for Basements, Bathrooms, Kitchens, Workshops. The fan was delivered on-time, complete, and as described by the seller. It was well-packaged in a custom box and included a user manual, 2-year warranty information, and hardware for mounting the speed controller. The cylindrical structure is sturdy and nicely finished, the plug-in power cable and speed controller are integrated and the fan runs smoothly with little vibration. The speed is continuously variable with a dial control from OFF to maximum; at highest speed it makes about as much noise as a pedestal fan….. the sound is principally from the airflow itself. The fan has steel blades and is designed to be mounted/suspended inline in an 8-inch diameter ductwork; there are no mounting brackets provided. I am using this fan, funning at medium speed, to increase ventilation in my attic with the expectation of improving the efficiency of my A/C system (also installing a reflective radiant barrier throughout); so far I am satisfied with the performance. I am using an Amazon Smart Plug with the Alexa application to run the fan on a regular routine and/or use voice commands to turn on and off remotely as needed. ## Frequently Bought Together - AC Infinity RAXIAL S8, Inline Booster Duct Fan 8” with Speed Controller - Low Noise Inline HVAC Blower Can Fan for Basements, Bathrooms, Kitchens, Workshops - LV-PUR131 Replacement Filters Compatible with LEVOIT LV-PUR131 and LV-PUR131S Air Purifier, LV-PUR131-RF, 2 Pack True HEPA and Activated Carbon Filters (2 HEPA + 2 Carbon Filters) - GE All Purpose Silicone Caulk - 100% Waterproof Silicone Sealant, Stronger Adhesion, Freeze & Sun Proof - 10 oz Cartridge, Clear, Pack of 1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/352350437-ac-infinity-raxial-s8-inline-booster-duct-fan-200mm-speed](https://www.desertcart.us/products/352350437-ac-infinity-raxial-s8-inline-booster-duct-fan-200mm-speed) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-03*
