Keep cool in harsh conditions

Dust tight and water resistant fans perform in extreme environments

NMB Fans are designed to perform in extreme conditions.

These fans keep your equipment operating at peak levels and reduce machine downtime. The fan motor is fully encapsulated by epoxy material to maintain optimal performance in high temperature and high pressure applications. NMB Fans provide resistance against oil, chemicals, water, and corrosion / rust. These IP rated fans meet or exceed IP67, IP68 and IP69K ingress protection requirements.

Welding application story

NMB's IP69K fans reduce power draw to provide continuous and reliable welding equipment operation. Learn more about how NMB's ingress-protection designation and fully encapsulated epoxy "potting" protects welding equipment from external debris.
