AI Technical Summary

Technical Problem

Traditional induced draft fans have single functions, insufficient adjustment flexibility, and poor environmental performance, especially poor adaptability in different ventilation volume scenarios.

Method used

An environmentally friendly induced draft fan that integrates angle adjustment, filtration and dust removal has been designed. The blade angle can be adjusted from 0° to 90° through the angle adjustment component. It is equipped with front and rear filter racks and dust removal components, combined with the locking angle component and adjustment mechanism to achieve automatic switching and stable locking. Combined with vibration dust removal, it can adapt to various usage scenarios.

Benefits of technology
