Purification fan technical requirements specification Nov 15, 2018

Wuxi Lantian Special Fan Co., Ltd. is a professional manufacturer of all kinds of purification fans, industrial fans and air-conditioning fans. It has a 16-year history, a complete fan testing center and a strong technical team.

Blue Sky Fan has always insisted on providing customers with high-quality products and first-class service, and adheres to strict technical standards in production:

Impeller performance

* Optimized design

The FFU fan is optimized by CFD flow field simulation. This design is more aerodynamic, more efficient and more stable.

 

* High balance level

Each impeller undergoes a dynamic balance test, insisting on the balance level of G4.0, which fundamentally ensures the long-term quiet and stable operation of the fan.

 

* Impeller process

The blade adopts steel laser cutting, precise fixture positioning and all-welding process to ensure smooth blade edge, accurate welding angle, high overall strength, uniform stress during long-term high-speed operation, and stable and reliable operation.

 

Features

* High reliability

The fan adopts auxiliary design to improve the reliability of the structure; the volute and the impeller are continuously welded with all steel, high strength and no leakage, which improves the safety of operation;

 

* high efficiency

The inlet guide ring is precisely matched with the front disc of the impeller to reduce turbulence and gas leakage, making the airflow smoother and improving the aerodynamic performance.

 

Specifications

* Fan type

The fan should be a steel back-bend impeller single-inlet centrifugal fan. The driving mode is direct connection, coupling or belt drive. The fan structure should be able to allow the impeller to be easily extracted for the impeller maintenance or cleaning.

 

* Quality Standard

The fan has passed the national industrial product production license and ISO9001 quality system certification.

 

* Fan impeller

The impeller shall be a steel back-bend centrifugal impeller and fully welded. The impeller should be statically and dynamically balanced to achieve

Standard G4.0 level. When the impeller is at the maximum allowable speed, it should be able to maintain a smooth airflow and low noise.

 

* Fan housing

The fan casing shall be of steel and shall be of sufficient thickness and strength to withstand the maximum operating weight of the fan. The fan casing should be continuously welded.

 

* Inlet

The air inlet of the fan should be designed in strict accordance with the aerodynamic characteristics. The surface is smooth and streamlined, and has a good rectifying effect, which can effectively reduce turbulence, improve fan efficiency and reduce noise.

 

* Surface treatment

The surface of the fan should be cleaned first to remove protruding foreign objects, welding slag, burrs, sharp edges, iron filings, and oil.

 

* Motor

The motor should be closely matched to the fan load, protection class IP54, insulation class F. The motor bearings should be ball bearings and lubricated. The motor and drive mechanism should be placed outside the airflow to avoid buildup of grease or dust in the airflow.
