Product Description

Introduction to Core Technologies
Air suspension turbo blower fan is a new type of CASON® Aerobic Vertical Fermentation Machine air supply system. The advantages of Air suspension turbo blower fan are as follows:
High efficiency, significant energy saving; Low noise, optimized working environment. 
Save space and reduce investment in auxiliary facilities. 
Simple operation, high degree of automation. 
No lubricating oil, no maintenance, high reliability of equipment.

(1) Principle of Air suspension turbo blower fan bearing
Startup, when the Air suspension turbo blower fan motor rotor shaft and relative movement, air bearing rotor shaft speed increase rapidly, along with the rotating shaft surface gas quickly create tension, make the open foil air bearing, bearing and shaft, the shaft and bearing air film formed between foils, using gas transmission, adsorption and condensability, A complete air film is formed under the aerodynamic dynamic effect, and the bearing of the Air suspension turbo blower fan supports the rotating shaft through the air film pressure field, so that the rotor shaft is in stable suspension state.


(2) Motor of Air suspension turbo blower fan
The Air suspension turbo blower fan adopts high speed permanent magnet synchronous motor. The motor of Air suspension turbo blower fan has convenient speed regulation, can easily realize stepless speed regulation; Wide speed range, large working speed range; Stable operation, no vibration, low noise; High efficiency (≥97%), no rotor loss; Less heat dissipation, life is much higher than ordinary AC motor; Small size, light weight, simple structure and other advantages.

Two parameters of Roots fan

Conclusion: The air volume of one air suspension fan is equal to that of two Roots fans. But the wind pressure is much higher than the roots fan. It consumes as much electricity as a single Roots fan. In practice, our fermenter works with two Roots fans. But only one air suspension fan is needed. According to practical operation, one air suspension fan (total power 9KW) can completely replace two Roots fans (bottom fan and fixed complementary fan, total power 24.2KW).
