IP68 DC Fans with PWM

NMB Technologies IP68 DC Fans with PWM provide better protection against dust and water ingress in harsh environments and other challenging outdoor applications.  These NMB DC fans incorporate IP68 protection (per IEC 60529/ISO20653), GR 487 Salt-Fog compliance (select models), and Sulfur gas and ammonia corrosion resistance. The IP68 fans offer long life and high reliability with precision machined stainless steel ball bearings. These 40mm to 172mm fans are available in 12V, 24V, and 48V models with tacho output for speed monitoring and PWM for precision fan speed control. The IP68 DC fans employ efficient motor technology and aerodynamic impeller design. Typical applications include EV/battery charging, power storage, 5G telecommunication, PV inverters, and heat exchangers.
