contact supplier for 1400mm Chicken Shed Fan

Forper box fan enters market with excellent quality,elegant appearance and optimal performance,widely used for ventilation in poultry&livestock houses,greenhouse and industrial factory buildings.

Selected materials

*Stainless steel blade from Krupp material

6 stainless steel blades are self cleaned,with a stamping process by computer mathematical model.

*Galvanized frame

Through strength test,square frame and round air guide sleeve are stamped and connected together by standard fasteners,using electric power and air tools.

Zn-coat thickness no less than 200 gram per square meter,resistant to corrosion and weathering.

*Louver leaves

Hot galvanized louver leaves are also made by stamping mold.

1.5mm-thick middle louver leaf supports plastic automatic centrifugal opening device,ensuring no deformation after operation for a long time.When fan stops operating,all leaves will close tight,leaving no leak for air or light.

*Taiwan-owned brand motor

1005 copper cored motor,with CCC authentication;

Power-1.1KW(50inch fan);.0.4KW(36inch fan);Protection grade-IP54; Insulation grade-F

*Belt wheel and wheel hub

Aluminum magnesium alloy material,die casted,with better corrosion resistance.

Water proofing groove in the belt wheel protects water against entering inside.

Built-in oil bearing in auto industry,maintenance-free.

Novel structure

*Automatic centrifugal opening device

Injected by reinforced nylon,bearing drive structure include.When powered,the centrifugal opening device pushes louver leaves quickly and flexibly,then ideal temperature and ventilation can be reached within a short period.

*Invisible handle

Both sides of every fan are equipped with handle,making easier for transportation.

Concave hole design avoids possible damage to handle when installation in the wall.

*Plug hole

On the bottom of every fan,plug hole is prepared to ensure the whole fan has no accumulated water at any time.

Many tests and inspection

Many kinds of testers are used for testing performance,such as anemometer,vibrometer,ampere meter,megameter,withstanding voltage testers,sound machine and others,to guarantee all advantages of Forper fan-high strength,large air volume,low noise and so on.

A static balancing testing-Weigh fan blades by electronic scale to ensure all the 6 blades of a fan have the same weight.

A dynamic balancing testing-Proof the angle of six halves of a flange to guarantee they have the same angel.

Another dynamic balancing testing-Test assembled blade and flange in operation by dynamic balancer to ensure equilibrium amount of each blade is no more than 1 gram.
