Outer frame:using the standard galvanized sheet,

the pressure muscle strengthen design with once

ramming formation; standardly produced by advanced

rivet craft assembly line;stable performance,can

compared favorably with the import product.

Shutter: having two kinds for choice: zinc plate and

stainless steel plate. Characteristics: good rust

prevention, sealing , lightproof.

Shutter linkage: made of new nylon material,

supporting linkage system,closing and opening

shutters rapidly and swiftly. Width:400mm,

increasing the loading capacity.

Automatic opening system: the transmission belt

uses automatic tight system, won’y relax, fall from

the belt,operated simply. The heavy hammer institution

utterly guarantees the shutter open and close safely,

avoiding the loss of wind volume caused by shutter

opening not to 90°.

Bearing: same as that in car wheel,

high intensity and duration.

Wheel and blade base: made of magnesium alloy,

using a stamping molding process, light weight,

fine performance,stable running.

Motor: Exported;
