The 624/2HH is a compact tube axial fan from EBM-Papst in a 60×60×25 mm format, powered by 24 V DC. With an airflow of up to 56 m³/h and a maximum static pressure of 125 Pa, it delivers efficient cooling in a small form factor. The plastic construction keeps the weight down to just 70 g.
The fan is ideal for cooling electronics, control cabinets, and industrial equipment where space is limited. The tachometer signal via open collector output makes it easy to monitor the speed in real-time.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 56 m³/h |
| Speed | 8,200 rpm |
| Power | 3.6 W |
| Voltage | 24V DC VAC |
| Motor frame | The housing is made of plastic and measures 60 × 60 mm with a depth of 25 mm. The fan weighs 70 g and can be mounted in any position. A tacho signal is available via an open collector output on a white wire in the cable. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is balanced to quality grade 6.3. The fan is an axial type with the airflow direction blowing over the struts. The maximum airflow at free blowing and nominal voltage is 56 m³/h, and the maximum static pressure is 125 Pa. |
| Bearing type | ball bearing |
| IP class | IP20 |
| Rotation direction | clockwise (viewed from the rotor side) |
| Motor type | The motor is an electronically commutated DC motor designed for 24 V nominal voltage with an operating voltage range of 18–28 V. A leakage protection diode is built in to protect against reverse polarity. The blocking protection means electronic restart in case of a locked rotor. Current consumption at nominal voltage and free blowing is 150 mA with a power consumption of 3.6 W. |
