The 4312U from EBM-Papst is a compact DC axial fan with a flanged housing, measuring 119 × 119 × 32 mm. The fan delivers an impressive airflow of 170 m³/h and is built for demanding environments thanks to its IP68 rating. With ball bearings and reverse polarity protection, it offers a long and reliable service life.
The fan is ideal for applications where moisture, dust, or harsh external conditions place high demands on durability – for example, in industry, marine environments, or outdoor installations. The optional mounting position makes it easy to integrate into existing systems.
