Product Overview

For equipment that simply needs reliable mains-powered airflow, the A803801 offers a 80 × 80 × 38 mm frame, dual-ball bearing options and a straightforward two-wire installation.

Every A803801 passes automated winding inspection, dynamic balancing and a full aging cycle before it leaves our Shenzhen factory. When you request a sample we verify the operating point against your system's resistance curve and can adjust speed, voltage range or output leads without tooling charges on standard sizes.

Frequently Asked Questions — A803801

Does A803801 connect directly to mains power?

Yes. A803801 runs directly on 110 V / 220 V AC, 50/60 Hz — no external power supply or driver is needed, which simplifies wiring inside cabinets and appliances.

Can the speed of A803801 be adjusted?

AC fans run at a fixed speed determined by mains frequency. If you need variable speed, we can quote an EC version of the same frame size with 0–10 V or PWM control.

What capacitor does A803801 use, and can it be replaced?

A803801 uses a certified running capacitor matched to the winding. Replacements are available from us; we do not recommend third-party capacitors with different capacitance or voltage ratings.

Is A803801 suitable for continuous 24/7 operation?

Yes. A803801 is designed for continuous duty in machine cabinets, welding equipment and workshop panels, with 100 % aging test before packing and an expected L10 life of about 30,000–40,000 h.
