Frequently Asked Questions

What is a cross flow fan?

A cross flow fan, also known as a tangential fan, moves air across the fan impeller rather than axially or radially. It provides uniform airflow over a wide area and is commonly used in air curtains, HVAC systems, and refrigeration units.

What are the advantages of DC vs AC cross flow fans?

DC fans offer variable speed control, lower power consumption, and quieter operation. AC fans are typically more cost-effective and suitable for fixed-speed applications.

Can I get custom fan sizes or voltages?

Yes, LONGWELL offers OEM and ODM services. We can customize fan dimensions, voltages, speeds, and mounting options to meet your specific requirements.

What is the typical lifespan of your fans?

Our cross flow fans are designed for long service life. Under normal operating conditions, AC fans last 30,000+ hours, while DC and EC motors can exceed 50,000 hours.

Do you provide technical support?

Yes, our engineering team provides full technical support, including selection guidance, installation advice, and troubleshooting assistance.
