The AC INFINITY RAXIAL S8, Inline Booster Duct Fan with Speed Controller, 8-Inch, is a high-efficiency solution designed to enhance airflow in a variety of residential and commercial settings. This robust fan is perfect for integrating into HVAC systems or for ventilating areas such as attics, workshops, bathrooms, and kitchens.
Superior Design and Construction:
- Unibody Die-Cast Construction: The RAXIAL S8 features a unique unibody design, eliminating the need for welded seams. This construction significantly reduces vibration, allowing for smoother and quieter airflow. It's a perfect blend of durability and performance.
- Matte Black Steel Cylinder: The fan's cylindrical body is designed for easy and secure installation. Its fluted and ridged structure not only adds to its aesthetic appeal but also ensures a firm fit within ducting systems, making it a versatile choice for different ventilation needs.
- Balanced Steel Blades and Dual-Ball Bearings: At its core, the RAXIAL S8 is equipped with balanced steel blades, ensuring efficient airflow across a range of applications. The blades are supported by permanently lubricated dual-ball bearings, extending the fan's lifespan to 67,000 hours. This feature also allows for flexible mounting, either horizontally or vertically, to suit various installation requirements.
Adjustable Airflow with Speed Control:
- Inline Variable Speed Controller: This fan comes with an easy-to-use knob controller, allowing you to adjust the fan speed according to your specific needs. Whether you require a gentle breeze or a strong gust, the RAXIAL S8 can deliver, offering up to 428 CFM of airflow. The noise level is kept to a manageable 43 dBA, ensuring effective operation without excessive noise.
- Secure Connectivity: The speed controller utilizes a female aviation plug with a metal retainer for a tight and secure connection to the fan. This reliable connection guarantees consistent performance and safety.
Versatile Applications:
The RAXIAL S8 is not just a booster for HVAC systems; it's also ideal for ventilating various home and commercial spaces. Whether it's removing stale air and odor from attics and basements or circulating fresh air in grow tents and indoor gardens, this fan is up to the task. However, it is not suitable for standalone use in high static pressure environments or in systems with restricted airflow, such as those using carbon filters.
