Product Overview

Compact but capable, the DC 8032 moves a useful volume of air through a 80 × 80 × 32 mm frame — a common retrofit size that drops into existing cut-outs without modification to the enclosure.

Each DC 8032 is bench-tested after a complete aging cycle at our Shenzhen facility, and test records are retained by serial batch. Tell us your voltage, duty point and environment and the confirmed curve for your order will match the sample you approved.

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: 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 — DC 8032

What is the MOQ for DC 8032? Can I buy samples first?

Sample orders of 1–5 pcs are accepted for evaluation. For volume orders of DC 8032, MOQ starts at 100 pcs for stock configurations and 500–1,000 pcs for custom voltage, cable or connector versions.

Can DC 8032 be ordered with PWM speed control or a tach signal?

Yes. The DC 8032 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 8032?

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 8032 reaches an L10 life of about 50,000 h at 40 °C.

What is the lead time for DC 8032?

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.
