产品特征：
With the development of ship industry, more and more attention has been paid to ship ventilation equipment. Our company adopts advanced variable loop design method, combined with CFD flow field simulation calculation and optimization to produce CZ-60-01 ~ CZ-180-01 series axial flow fans. The impeller is combined type, hub ratio, blade installation Angle, blade and hub optimal matching can be adjusted according to the performance. Its advantages are detailed as follows:
1. performance: fan performance range is wide, blade installation Angle is adjustable, easy to adapt to the requirements of different working conditions of Marine axial flow fan design, production.
2. Noise: the difference between its octave-band sound pressure level and the original cast aluminum impeller is more obvious. The noise of A sound level is 1 ~ 3dB(A) lower.
3. efficiency: efficiency is 2 ~ 5% higher than the overall cast aluminum impeller fan.
4. weight: light weight, reasonable axial size, convenient maintenance and replacement.
