Product Overview

For equipment that simply needs reliable mains-powered airflow, the A702502 offers a 70 × 70 × 25 mm frame, dual-ball bearing options and a straightforward two-wire installation.

Production of the A702502 is vertically integrated: winding, impeller balancing, assembly and burn-in happen in-house, and each unit is functionally tested before shipment. Samples are validated at your stated duty point so the mass-production curve matches what you measured.

Key Features

Direct 110 V / 220 V mains connection — no external power supply required

Frequently Asked Questions — A702502

Does A702502 connect directly to mains power?

Yes. A702502 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 A702502 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 A702502 use, and can it be replaced?

A702502 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 A702502 suitable for continuous 24/7 operation?

Yes. A702502 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.
