Robust Construction and Design:
- Unibody Die-Cast Framework: The RAXIAL S4 features a unique unibody design with no welded seams, significantly reducing vibration for quieter operation. This solid construction ensures smooth, low-resistance airflow, enhancing overall efficiency.
- Matte Black Steel Cylinder: The fluted and ridged steel cylinder offers not only a sleek appearance but also practical functionality. Its design facilitates easy and secure installation within ducting systems, making it a versatile choice for various settings.
- Optimized Blade Design: Equipped with balanced steel blades, the fan achieves optimal airflow while maintaining minimal noise levels. These blades are designed for durability, backed by a 67,000-hour lifespan, and are supported by permanently lubricated dual-ball bearings, eliminating the need for regular maintenance.
Variable Speed Control for Customized Airflow:
Inline Speed Controller: The included speed controller provides easy adjustment of the fan's operation. With a simple turn of the knob, you can modify the fan speed to achieve the desired airflow and noise level. The controller's speed range includes low, medium, and high settings, producing up to 106 CFM of airflow with a noise level as low as 28 dBA.
Secure Connection: The speed controller utilizes a female aviation plug with a metal retainer, ensuring a reliable and secure connection to the booster duct fan.
Versatile Applications:
The RAXIAL S4 is suitable for various applications where enhanced air delivery is required. It can be used to boost airflow from HVAC units in residential settings, effectively ventilating spaces such as attics, workshops, kitchens, and basements. It also finds application in grow tents, rooms, and indoor gardens as an intake fan to bring in fresh air. However, it's important to note that this fan is not suitable for standalone use in high static pressure applications or systems with restricted airflow, such as those using carbon filters.
