Product Details
The SXDE4020 EC Energy-Saving Series (40x40x20mm) is SXDOOL's smallest AC 115V / 230V universal-voltage cooling fan. Despite its compact 40mm body, it delivers high speed, high static pressure, and high airflow (up to 8.8 CFM) with the energy efficiency of EC (Electronically Commutated) brushless motor technology. Built with a long-life Dual Ball Bearing system rated for 70,000 hours, it runs on a single global-voltage input (115V & 230V), making it ideal for telecom cabinets, power supplies, industrial controls, and instrumentation worldwide. Speed can be customized even higher on request. Waterproof (IP) rating available on customization.

❓ Frequently Asked Questions (FAQ)
Q: What is an EC energy-saving fan and how is it different from a standard AC fan?
A: An EC (Electronically Commutated) fan uses a brushless DC motor internally with an integrated AC-to-DC controller, so it runs directly on AC mains (115V/230V) while consuming significantly less power than a traditional shaded-pole AC fan. The SXDE4020 EC fan combines AC plug-and-play convenience with DC-level efficiency and speed control.
Q: Does the SXDE4020 fan work on both 115V and 230V?
A: Yes. The SXDE4020BH is a universal-voltage EC fan that accepts AC 115V and 230V input, so a single SKU can be deployed globally without changing the part for different regions.
Q: How small is the SXDE4020 and what is its airflow?
A: It measures just 40 x 40 x 20 mm — one of the smallest AC/EC fans available — yet delivers up to 8.8 CFM airflow at up to 8000 RPM, making it suitable for dense, space-constrained enclosures.
Q: What is the expected lifespan and bearing type?
A: The fan uses a dual ball bearing rated for 70,000 hours of operation at 40°C, ensuring high reliability in continuous-duty industrial applications.
Q: Can the speed be customized higher, and is a waterproof version available?
A: Yes. Speed can be customized above the standard 5000–8000 RPM range based on your thermal requirement, and IP-rated waterproof versions (e.g. IP55 / IP68) are available on request.
Q: What is the MOQ and lead time for OEM orders?
A: As a source factory (SXDOOL / Sensda Electronics Limited), the standard MOQ is 100 pcs with a lead time of 7–14 days. Custom wire, connector, label, and certification options are supported.
