Professional industrial roof exhaust fan with CE certificate

1. Yinuo ventilation fan for poultry house frame made from highly galvanised steel sheets  in order to assure highest strength and strong resistance to corrosion.

2. Six pieces stainless steel blades and the fan has all passed the experiment of homeostasis with big air volume, without deformation, no breaking, attractive and durable.

3. The V type belt pulley is aluminium magnesium alloy injection moulded, light weight, high-strength.

Main Components

Fan bearing adopts imported double-row bearing with special waterproof design, water can’t enter. High strength, lower noise, maintenance free and long service life.

Fan belt pulley is made of high strength aluminum-magnesium alloy by die-casting which reduces the weight of blade impeller complete, high corrosion resistance. Special three reinforced ribs pulley design. Blast sanding treatment for attractive appearance, eliminate internal stress to improve its own rigidity and stability.

Motor have domestic brand motor and Siemens motor can be chosen. Motor voltage and frequency can be customized. Domestic brand motor joining open phase protection device. When the lack of power, can carry out their own power to control; Motor protection grade IP 55, insulation class: F.

Fan blade is made of stainless steel by punch forming, no dust, attractive and durable. Special blades shape design ensure large air volume, no deformation, no broken, keep air volume same all the way, Thickness 1.2mm, surface finish BA grade.

Using high strength nylon pendulum opening device, shutters opening and closing flexible stabilization.

Fan blade are advanced through the computer dynamic balance measuring instrument calibration, Dynamic balance control in 1 g, The fan running smoothly , The blower to smooth running, small vibration, low noise, enhances the stability of the whole machine. Fan blade materials are stainless steel, galvanized plate, aluminum alloy three kinds of optional material.

Use imports belt, to ensure that the service life, Maintenance free; The service life of the belt in a type A on the basis of an increase of 3 times.

Using the most advanced automatic belt tensioner to ensure working efficiency and good performance.

In order to facilitate handing, fan on both sides of the fuselage design of the recessed plastic handle, convenient transportation, improve transport efficiency, and reasonable design, beautiful appearance, not to hurt the hand, not easy to damage.
