The 3314NNU from EBM-Papst is a compact DC axial fan with a wall ring, measuring 92 × 92 × 32 mm. The fan is built for demanding environments thanks to its IP68 rating and stainless steel ball bearings. The brushless DC motor operates within a wide voltage range of 12–28 V DC with 24 V as the nominal value.
The fan is ideal for applications where moisture, dust, or immersion may occur – for example, in marine technology, the food industry, or outdoor installations. The optional mounting position and the included 310 mm cable make installation easy and flexible.
