Consumer-grade blowers usually fail to start properly at low temperatures. Especially below -40 degrees Celsius. The performance is as follows：
The main reasons for the failure of the blower to operate at low temperatures are generally two reasons: one is the mechanical structure, especially the grease in the roller bearings; the other is the electronic drive components.
1. we used NMB two ball bearing: R-1350ZZMTRP5P24LY121,it's operating temperature can be -50~+150.
2.Use special driver electronic components
All electronic components can work under -50 degree envirment.high pressure blower can work well.But when you need this kinds of special blower,please inform us the temperature envirment.because normal dc blower just can work under -40 degree envirment only.This is very importan.
