The technological breakthrough of the 4RB 610 AH16 is reflected in its pressure-flow ratio and energ

Through the precise coordination of multi-stage tandem impeller and annular flow channel, this model can achieve a conveying pressure of 360mbar at 2.2KW power, which is 40% higher than the pressure of roots fans of the same power, and is suitable for scenarios that need to penetrate high-density sludge layers. Its impeller and shaft are sealed and dust-proof, which can effectively block impurities such as grease and fiber in food wastewater, and avoid the performance attenuation of traditional fans caused by impeller fouling.

For corrosive environments in food wastewater treatment, the model is equipped with NSK high-speed hermetic bearings and stainless steel impellers as standard, and is IP54 certified. There are three points to focus on in daily maintenance:

Cleaning of the filtration system: check the filter screen of the air inlet every month, and use a high-pressure air gun to remove grease and fiber accumulation to avoid air volume attenuation;

Bearing lubrication: 7018 high-speed grease is supplemented every 2000 hours, focusing on lubricating the rear end bearing of the motor and the front end bearing of the impeller;

Vibration monitoring: Through the vibration sensor built into the anti-vibration base, the operating status of the equipment is monitored in real time, and the impeller dynamic balance needs to be checked when the vibration value exceeds 5mm/s.

If there is a pressure drop or abnormal noise, you can check according to the process of "checking the resistance of the pipe network→ verifying the motor steering →detecting impeller wear". The model is CE certified and can be customized in an explosion-proof version to meet the dual safety needs of food processing plants.
