is the form of impeller as follows:“leafy, forward direction, narrow wheel”, it has a series characters of big flow zone, accelerate circulation of fluid flow, and when Convection cell strong pressure, it produces small eddy. It has advantages of large Air flow, high air pressure, low noise etc. It is widely used in the machinery industry of printing, packing, plastic, blueprint etc, it also can be used in every occasion, such as food, temperature-controlled and aeration.
The motor of this fan has passed the national mandatory product certification (hereinafter referred to as CCC), and we own Chinese Country Compulsory Product Authentication Certificate, which is issued by China Quality Certification Center.
