Q: What brands of fans can be upgraded?

A: We offer upgrades for SPAL, Mishimoto, and Maradyne fans.


Q: How long does the upgrade process take?

A: The standard turnaround time is a minimum of 5 business days upon receiving the fan. The customer is responsible for shipping the fan to Steele's facility. When selecting the quantity, enter the number of fans needed for the upgrade. A follow-up email from Steele's staff will provide the shipping address and detailed turnaround time.


Q: How does the soft start technology benefit my vehicle's electrical system?

A: Soft start technology gradually increases power usage to prevent sharp spikes in current, which can protect your vehicle's electrical components from potential damage and improve overall system reliability.


Q: How does the PWM sensor control work?

 A: The PWM sensor control allows for proportional fan speed control through your Power Distribution Module (PDM) with a frequency range between 50-200Hz, starting at 15% and going up to 100% full speed. This model includes an additional wire that connects to a PWM controller, compatible with many PWM sources within the specified frequency range. Additionally, if the PWM signal is lost, the fan has a built-in failsafe that automatically runs the fan at full speed to ensure continuous cooling. We also offer a standard model with a soft start feature for steady performance without PWM. 


Q: Can I install the Steele Brushless Electric Fan myself, or do I need a professional?

A: Professional installation is recommended to ensure optimal performance and reliability.


Q: How does the fan's IP68 rating benefit me?

A: The IP68 rating means the fan is completely dust-tight and can withstand immersion in water up to a certain depth, making it ideal for off-road and extreme weather conditions.


Q: What is the expected lifespan of the Steele 10" Brushless Electric Fan?

A: The fan is designed with a duty cycle of 50,000 hours, ensuring long-lasting performance and reliability under various operating conditions.


Q: What makes the brushless motor superior to traditional brushed motors?

A: Brushless motors are more efficient, have longer lifespans, and produce less heat compared to traditional brushed motors. They also require less maintenance and provide more consistent performance.
