Product Overview

Where panel space is tight but heat load is not, the DC 9020 offers a practical answer: a 90 × 90 × 20 mm DC axial fan with multiple voltage and signal options for integration into new or existing designs.

Production of the DC 9020 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

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: Typical performance at nominal voltage. For designs near thermal limits we recommend a sample test at your enclosure's operating condition before release.

Typical Applications

Industrial control cabinets Power supplies & inverters Telecom & network equipment Medical devices Consumer electronics 3D printers & CNC

Frequently Asked Questions — DC 9020

What is the MOQ for DC 9020? Can I buy samples first?

Sample orders of 1–5 pcs are accepted for evaluation. For volume orders of DC 9020, MOQ starts at 100 pcs for stock configurations and 500–1,000 pcs for custom voltage, cable or connector versions.

Can DC 9020 be ordered with PWM speed control or a tach signal?

Yes. The DC 9020 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 9020?

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 9020 reaches an L10 life of about 50,000 h at 40 °C.

What is the lead time for DC 9020?

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.
