Product Introduction

7-28 type medium-pressure centrifugal fan is a newly developed high-efficiency series of industrial centrifugal ventilation fans by our company. With a maximum efficiency of 87%, it belongs to the small-flow, medium-pressure series, offering stable performance and a wide high-efficiency range. It is widely used in environmental protection dust removal, material transportation, and industrial equipment matching.

Product Features:

①This series of fans belongs to the small-flow, medium-pressure category of new high-efficiency industrial fans.

②The collector and the front disc of the impeller are processed using advanced spinning technology, ensuring precision.

③C/D type fans are equipped with integrated bearing boxes, ensuring good lubrication, stable operation, and long bearing life.

④Equipped with a tapered sleeve embedded pulley, making disassembly and assembly easy.

⑤The collector is configured with mounting flanges, facilitating customer connection to pipelines.
