Performance characteristics:

1、Reasonable cone design: Allows for the concentrationof airpressure and direction which results in biggerairflow. It isenergy-efficient and exhibits a lower noise level;

2、The frame is composed of hot galvanized steel madewithadvanced auto-machining techniques. The thicknessof thegalvanized layer is 275g/ m²;

3、Model 430BA: Each fan is composed of 6 stainlesssteelblades. A balance test is performed to ensure thatweight issimilar among the blades.

Main technical parameters：

FAFW蝴蝶门式拢风筒风机

Galvanized steel frame: made of 275g/m2. Providesrust protection.

Using an advanced front double door opening device, smallwind resistance, good sealing, and high efficiency are provided. A lengthened cone design

Fan double doors are closed with the rubber sealing which effectively prevents air backflow when the fan is started at different times. This greatly improves the operating efficiency by 15-20%, as compared with a fan of the same power.

fan blades are especially designed for top grade efficiency, being made of Krupp stainless steel by punch forming. It moves a large volume of air and exhibits no deformation, breakage or dust. It is attractive and durable. Thickness: 1.2mm, surface finish: BA grade.
