Direct 315mm Industrial Axial Flow Fan, the bending strength of not less than 196Mpa, each section with smooth, smooth surface, no
cracks, gaps, burrs and other defects, the overall effect is good, the fan to do static balance test, according to the "balance
precision" rigid rotor, grade G6.3 level, from the cylinder wall gap 30mm tip and the error is no more than 10mm, the fan
aerodynamic reasonable, large volume, low noise, high efficiency, corrosion resistance.
