Product Overview

The DC 9038 is a 90 × 90 × 38 mm DC axial fan built around a high-static-pressure impeller, sized for spot cooling of PCBs, power modules and control cabinets where steady airflow matters more than peak noise figures.

Every DC 9038 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.

Key Features

Available in 5 V, 12 V, 24 V and 48 V DC to match your existing power rail
PWM (4-wire) or tachometer (3-wire) signal versions for closed-loop speed control
Sleeve, one-ball or dual-ball bearing options matched to mounting orientation and ambient temperature
Frame and impeller in flame-retardant UL94 V-0 reinforced plastic
Lead-wire, JST / Molex connector or terminal options; IP-rated waterproof versions on request
RoHS compliant; CE-certified series available for export projects

Note: Values above are typical catalogue figures at rated voltage, 25 °C. Final specification is issued with your order confirmation after we verify the duty point.

Frequently Asked Questions — DC 9038

What is the MOQ for DC 9038? Can I buy samples first?

Sample orders of 1–5 pcs are accepted for evaluation. For volume orders of DC 9038, MOQ starts at 100 pcs for stock configurations and 500–1,000 pcs for custom voltage, cable or connector versions.

Can DC 9038 be ordered with PWM speed control or a tach signal?

Yes. The DC 9038 DC platform supports 4-wire PWM (25 kHz), voltage speed control, tach (FG) output and locked-rotor alarm (RD). Tell us your control board interface and we will match the wire harness.

Which bearing should I choose for DC 9038?

Sleeve bearings suit horizontal mounting and budgets; one-ball or dual-ball versions are recommended for vertical mounting, high ambient temperature and 24/7 duty. Dual-ball DC 9038 reaches an L10 life of about 50,000 h at 40 °C.

What is the lead time for DC 9038?

Samples ship in 5–7 working days. Mass production is typically 15–25 days depending on quantity; urgent orders can be scheduled with the production planner on request.
