Blade material have stainless steel ,galvanized sheet, aluminum alloy, FRP for option 8.Using the most advanced automatic belt tensioner to ensure working efficiency and good performance.
9.Hot-dip galvanized blade support and safe net ensure never rust.
10.Complete new CNC production line improved fan quality up to top grade, aesthetic appearance.

Ventilation principle
Shutter mount exhaust fans discharge the indoor air, and reduce air pressure in order to achieve a cooling effect.
When industrial plants use a shutter mount exhaust fan, the air flows to the fan through the air inlet to form an air convection effect. In this process, the doors and windows near the shutter mount exhaust fan are closed to force the air to flow in the workshop through the windows and doors at the side of air inlet.
Our equipment features through and efficient ventilation with a ventilation rate as high as 99%. Our ventilation cooling equipment is suitable for your choice and requirements.
Ventilation speed and wind speed can be designed according to exact user needs, and any ventilation problems, such as harmful gas, smoke and dust can be quickly discharged in just a few seconds from starting the fan.

Application
1. Heat treatment plants, casing plants, plastic plants, aluminum factory, shoes factory, leather factory, electroplating factory, printing and dyeing plants, and chemical plants.
2. Suitable for labor-intensive enterprises, such as garment factories, assembly plants and internet cafes.
3. It is used for ventilation and cooling of gardening greenhouses and livestock farms.
4. Typically suitable for the places in need of cooling and humidity, such as cotton mill, wool factory, linen plant, weaving factory, chemical fiber plant, warp knitting plant, draw texturing factory, knitting mill, silk weaving mill, socks factory and other mills.
5. Applicable for a variety of storage and logistic industries.
