F-class insulation high temperature resistant fan

Axial flow fan features, while the blades are designed into a wide forward-swept equal-pitch structure, which can reduce the separation of airflow on the blade surface and the formation of airflow vortexes, reduce the secondary loss of airflow in the fan, reduce the aerodynamic noise of the sound source, and stabilize the airflow.

The fan impeller is made of steel, the hub is hydraulically stretched, the blades are hydraulically formed after stamping, and the blades and hub are welded and assembled. The impeller is statically and dynamically balanced, and the balance accuracy is not greater than G5.6. The outer cylinder flange is made of integral flanging and spinning.

It has the characteristics of large air volume, low noise, and stable performance. It uses a high-temperature resistant motor with insulation grade F and is equipped with a special motor cooling system to avoid direct contact between the airflow and the motor, reduce harmful gases, and the damage of high-temperature gases to the motor. It has excellent performance, good high-temperature resistance, high efficiency, less land occupation than centrifugal fans, and convenient installation and transportation.

The new product is designed and developed by the company's technical department and relevant colleges and universities using advanced CAD software. According to the test results of the organization, the fan efficiency is greater than 85%, and some large models are greater than 90%. It has the characteristics of a flat efficiency curve, which is conducive to energy conservation and environmental protection, and advocates green and low-carbon;

The basic form is an axial flow fan or a mixed flow fan, which can be directly connected to the air duct or mounted on the wall. The installation form can be vertical horizontal floor installation and hoisting. Floor installation requires the installation of a shock absorption system; high-strength spring shock absorption pads, rubber shock absorption pads, and the hoisting uses a spring shock absorption hanger fixed with a screw rod. The installation of a shock absorption system effectively attenuates the vibration of the machine itself, reduces the outward transmission of vibration force, prevents the transmission of vibration force, and ensures the normal operation of the fan.
