SOTOP IP55 Waterproof Metal Blades Axial Fan, 115V AC 120mm x 38mm High Speed, for DIY Cooling Ventilation Exhaust Projects

IP55 Graded
IP55 metal impeller is designed for moist and dusty environments and meets the waterproof and dustproof parameters of the IP55 water protection standard.
Sotop Axial Fan Series
Features excellent heat dissipation, and is effective in reducing the bearing temperature, thus prolonging the service life of the blower. Considerable rises in temperature are inevitable in the inner part of the blower during work. If the bearings are exposed to high-temperature for a very long time and the heat fails to dissipate, the service life of the bearings will be in risk, and the efficiency of the working machine will be influenced. In order to reduce the negative effects brought on by the rising temperatures, a cooling device is critical and necessary.
Oxidation-resistant metal fan blade
What makes Sotop Axial Fan Series stand out is the oxidation-resistant metal fan blade. It performs much better in heat dissipation and has a much longer life span than the usual plastic counterparts. The majority of existing blowers made of PBT or PC material are not capable of blocking the incoming electromagnetic waves. With the help of Sotop oxidation-resistant metal fan blades, the disturbances from electromagnetic waves are eliminated at the largest extent. Assisted by the surface treatment technology, oxidation will not happen on metal fan blades even through extended exposure in natural environments.
