Structure and principle
This High Class Fan is composed of a blade, motor, outer frame, protecting nets andsupporting frames and shutters .The shutters are opened by the Push-Pull certrifugal system. The Majar parts are made of galvanized steel sheets (180g/275g/M2) zinc coating ) andstainless steel sheets. Based on sound aerodynamic principles, wind resistance in minimized and efficient airflow isachieved. All products are used in a wide range of settings , including various types of farms ,greenhouses and factory buildings.
Motor Brand: Chinese motor and Siemens motor Certificate: CCC Protection class: IP55 grade Insulation class: F grade Volt and frequency:Customized Production:With phase failure protective device to ensure motor working well Advantage: Pure copper wire,High-efficiency,Energy-saving.
