Product Overview

Designed for continuous duty, the DC 9032 pairs a 90 × 90 × 32 mm frame with a thickened 32 mm blade channel, giving installers a balance of airflow, static pressure and low profile for electronics racks.

DC 9032 units are produced on our own winding and impeller-balancing lines in Shenzhen, then 100 % aging-tested before packing. Performance figures in the table reflect typical delivered values; we confirm exact curves against your enclosure resistance during sampling, and speed, voltage window or connector can be tuned at no tooling cost for standard frames.

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: Figures shown are standard-configuration values. Custom speed bins, voltage windows and bearing grades are quoted against your requirement.

Frequently Asked Questions — DC 9032

What is the MOQ for DC 9032? Can I buy samples first?

Sample orders of 1–5 pcs are accepted for evaluation. For volume orders of DC 9032, MOQ starts at 100 pcs for stock configurations and 500–1,000 pcs for custom voltage, cable or connector versions.

Can DC 9032 be ordered with PWM speed control or a tach signal?

Yes. The DC 9032 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 9032?

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 9032 reaches an L10 life of about 50,000 h at 40 °C.

What is the lead time for DC 9032?

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.
