About D series multi-stage centrifugal blower
 

D series Multi-stage Centrifugal Blower is designed by famous institute in China and engineers of B-Tohin. The blower has several impellers connected by connection rod. The inlet air is compressed stage by stage and finally discharge air capacity from outlet.

Specifications

Main Characteristics

·Low noise: there is no mechanical friction during the air blowing operation, and reasonable blade profile is adopted to minimize the noise.

·Small vibration: the optimized impeller reduces the axial force to the minimum so that the whole machine can run smoothly.

·Non-mechanical friction machinery: no gear speed-up is required. The blower rotor is supported by two bearings at the front and rear. During operation, there is no mechanical friction between any parts except the bearings, so noise caused by mechanical friction is avoided, thus ensuring the longest service life of the blower host.

·Convenient adjustment of airflow: the adjustment range of the blower's airflow is 50%~100%, which is adjusted by operating the butterfly valve at the inlet.

·Oil-free machinery: no oil and gas will be generated during the pressurization process of the blower, so as to ensure that the aerator will not be corroded, and improve the service life of the aeration system.

.Water cooling is adopted for the rear bearing, which extend sits service life.

·Advanced technology adopted for the rotor for achieving with high strength and long service life.
