Wall Mount Box Type Galvanized Ventilation Exhaust Fan

⊙ Specially designed fan blade shape with self-cleaning function ensures efficient fan operation. The blades are stamped and moulded in stainless steel and tested and calibrated by an advanced computerised dynamic balance measuring instrument to ensure smooth operation, low vibration, low noise and high airflow.

⊙ The centrifugal opening system is adopted to ensure that the blinds are opened and closed completely, and that the wind resistance is minimised and the airflow is maximised when the blinds are opened.

⊙ Rolling shutter connecting fittings are made of high-quality nylon material, which has a long service life, is easy to open, and ensures that the shutter is unchanged and works stably.

⊙ The frame is made of hot-dip galvanised sheet with a zinc layer thickness of 275q/m', and the shutters are made of galvanised sheet with thicknesses of 0.8mm and 1.5mm to ensure that the shutters are undeformed and stable in operation.

--> Centrifugal system can open the shuttles at a complete 90 degrees to ensure the lowest air resistance and biggest air volume.

--> Type B belt imported from Japan, ensures long service life

--> Siemens motor and Chinese famous motor are available.

--> Voltage and frequency can be customized.

--> Fan belt pulley and flange, with lightweight and lower vibration, are made of high-strength aluminum-magnesium alloy by die-casting.

--> Blast-sanding treatment for an attractive appearance and eliminate internal stress.

Heavy-duty industrial exhaust fan is especially suitable for cooling and wet areas. Such as cotton mills, wool factories, flax factories, weaving factories, chemical fiber factories, warp knitting factories, elastic factories, knitting factories, silk factories, socks factories, and other textile mills. Suitable for storage and logistics fields, greenhouse ventilation cooling, and livestock farm cooling.
