The 6448U from EBM Papst is a robust tubeaxial DC fan, built for demanding environments where reliability is critical. With a compact die-cast aluminum housing (172 × 150 × 51 mm) and an IP68 rating, it can withstand permanent immersion in water and is completely dust-tight. This makes it a unique choice for industrial applications with extreme environmental requirements.
The fan is perfectly suited for applications in marine technology, process industry, electronics cooling, and other environments where moisture, dust, or chemicals are an issue. The operating temperature range of -20 to +67 °C provides additional flexibility.
