5 Structure

The FRP anticentripetal ventilator 2.8A-6A is made of leaf-wheel,encloser,windsender,machine support and motor.6D-12D,6C-12C has transmission system.

1. It is after being from 10 piece in impeller it is curved for wing type blades, garden arc types record with after record form, Produce with the glass fibre reinforced plastic, smooth obstruction is lost lightly on the surface, one is streamlined structure that the structure compactness, whole gas flow, Have improved the motive force performance of air.

2.Chassis adopt glass fibre reinforced plastic whole shaping also with person who enters wind, collect person who flow for round arc curved surface, The impeller enters the wind even in speed, guarantee the working efficiency of the impeller

3.The chassis of the air blower, electrical machinery are fixed on the framework with the bolt , have good globality. No6C-12C, 6D-12D air blower adopt the transmission group with 4-72 air blowers of metal of the number of the machine.
