40x40x28mm DC Axial Waterproof Cooling Fan 4028 With High Speed Used On Power Supply Or Servers

What is a DC cooling fan?
DC fans also known as DC Brushless Fans are basically cooling fans engineered to meet requirements such as higher air flows at high static pressures. RENGANG manufactures Brushless DC fans in varied sizes ranging from 60 mm to 280 mm. These fans are available in the plastic blade as well as the metal blade.

What are axial fans used for?
In general, an axial-flow fan is suitable for a larger flow rate with a relatively small pressure gain and a centrifugal fan for a comparatively smaller flow rate and a large pressure rise. They are used to supply fresh air, suck air from return air trenches, suck air from rotary filters, exhaust air out, etc.
