The 6224NMU from EBM-Papst is a robust DC tubeaxial fan, specially designed for demanding environments where high sealing is crucial. The housing is made of die-cast aluminum with dimensions of Ø172 × 51 mm, and the motor is fully encapsulated to achieve an IP68 protection rating. This makes it ideal for applications where exposure to water, dust, or other environmental stresses is a factor.
The fan is excellently suited for industrial, marine, and outdoor applications where reliable operation under harsh conditions is required without compromising performance.
