The 632/2HPU from EBM-Papst is a compact DC axial fan with a flange, designed for demanding environments where high operational reliability is crucial. The fan measures 60×60×25.4 mm and is rated IP68, which means complete protection against dust and continuous submersion in water. With a stainless steel ball bearing and plastic housing, it combines long lifespan with light weight.
Thanks to PWM control, tach signal, and automatic restart upon locked rotor, the 632/2HPU is excellently suited for applications in medical equipment, marine environments, industry, and other demanding installations where reliability and weather resistance are required.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 44 m³/h |
| Speed | 6,300 rpm |
| Power | 1.6 W |
| Voltage | 12 V DC VAC |
| Motor frame | The housing is made of plastic and is square, measuring 60×60×25.4 mm with a depth of 25.4 mm. ISO 4762 M4 mounting screws, degreased, without extra washer or support, are used for mounting. The mounting position can be arbitrary along the axis direction. The maximum tightening torque varies depending on the corner: 30 Ncm at the cable outlet corner and 70 Ncm at the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and mounted on an axial fan with dimensions of 60×60×25.4 mm. With free air delivery and 100% PWM, an airflow of 44 m³/h and a maximum static pressure of 125 Pa are achieved. The airflow is directed from the intake over the struts. The direction of rotation is clockwise when viewed from the rotor side. |
| Bearing type | stainless steel ball bearing |
| IP class | IP68 |
| Motor code | VWCD060XHEFS |
| Rotation direction | clockwise |
| Motor type | The motor is an electronically speed-controlled DC motor with a nominal voltage of 12 V and a voltage range of 10.8–13.2 V. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. PWM control (1–30 kHz) enables variable speed control. The motor is equipped with a tacho signal (open collector) for speed measurement. |
