Low Noise Small Size Centrifugal Blower Fan Diameter 220mm (C2E-250.56C)

Single Inlet Forward Centrifugal fans and blowers are compact units that can be used to either pressurize or evacuate in air moving applications. The impellers are permanently mounted to the external rotors for ease of installation and maintenance-free operation.

  • Description

    With exquisite craftsmanship and specialized design, we have created more and more perfect EC Refrigerator Fan Motor, shaded pole fan motor, Compact Axial Fans to offer better product for our customers. In order to foster a good environment for the development of our company, we implement entrepreneurial principles in business development, including adopting flexible working hours and relaxing the dress code. With an open and inclusive attitude, our company actively integrates and coordinates the development of different industries. Any requires from you will be paid with our best attention! We must abide by and quantify the company's management system in an all-round way, and innovate and revise the system based on the principle of management needs.

    Single Inlet Forward Centrifugal fans and blowers are compact units that can be used to either pressurize or evacuate in air moving applications. The impellers are permanently mounted to the external rotors for ease of installation and maintenance-free operation. These units may be mounted in any orientation to provide maximum airflow in minimum areas.
    Forward centrifugal blowers always require scroll housing, which is open on one side. The characteristic features of this product series are high efficiency, a low noise level, relatively small air flow with a high increase in static pressure, robust design and space-saving application.
