Product Overview

Built around an all-metal housing and aluminium alloy impeller, the A402001 is a 40 × 40 × 20 mm AC axial fan intended for sustained industrial duty at ambient temperatures up to 85 °C.

Our Shenzhen line builds the A402001 end to end — winding, balancing, assembly and 100 % aging. Because no step is outsourced, we can hold batch consistency and adjust bearing grade, lead length or speed binning to your production schedule.

Key Features

Direct 110 V / 220 V mains connection — no external power supply required
Impeller options in aluminium alloy or reinforced plastic
Dual-ball bearing versions for vertical mounting and long service life
Auto-restart and polarity-protected motor design for continuous duty
Terminal box or lead-wire connection options
CE certified; built to run 24/7 in dusty industrial environments

Note: Specification values are representative; measured performance depends on system resistance and ambient temperature. Ask for the measured P-Q curve with your sample.

Frequently Asked Questions — A402001

Does A402001 connect directly to mains power?

Yes. A402001 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 A402001 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 A402001 use, and can it be replaced?

A402001 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 A402001 suitable for continuous 24/7 operation?

Yes. A402001 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.
