3314 NHH DC Axial Fan: High-Performance Cooling Solution for PLC Industrial Automation Systems
On this page
What is the ebm-papst 3314 NHH fan?
A brand-new ebm-papst 3314 NHH DC axial cooling fan — the 92 × 92 mm square DC fan that inverter and drive manufacturers fit as standard cabinet airflow. The hub label carries the full rating: 3314NHH · 24V⎓DC 3.4W 320mA ZP · (12–28V⎓DC) · +RD −BK — a 24 V DC nominal motor that accepts anything from 12 to 28 V DC, drawing 3.4 W / 320 mA, with red (+) and black (−) leads ending in a 2-pin white plug. It is Hungarian production (HUNGARY (Y), code 45.10) from ebm-papst St. Georgen, carrying the SF, VDE, cULus and CE marks, five glass-fibre blades in a black frame, and the 32 mm-deep body of the 3314 family. Nine pieces, new, recorded 1 December 2025 at about 0.5 kg as recorded. Nine photos plus the warehouse video below.

Why the 12–28 V window matters
The single most useful line on this fan's label is the parenthetical: (12–28V⎓DC). A nominal 24 V fan that also tolerates 12 V survives the real conditions of a drive cabinet — the same supply that sags during a motor ramp, or a 24 V rail that drifts high when the cabinet battery floats — without the bearing-stress and noise penalties of running a fixed-voltage fan off a dirty rail. For maintenance buyers the rest is straightforward: match the 92 mm frame and 32 mm depth to the panel cutout, keep the airflow arrow (moulded on the frame side) pointing the way your thermal design expects, and mind polarity at the 2-pin plug — the leads are marked +RD/−BK on the label, and these fans run but age fast when reversed. If your spares shelf holds cabinets built around the 3314 family, this lot is the drop-in restock; all nine photographed pieces are unused, with factory-crisp labels and unmarked blades.
