Popular in Australia Rooftop Air Ventilator  

Introduction of vacuum Cooling Fan:

Vacuum cooling fan is based on the theory cross ventilation and vacuum air charge.Fresh air comes from  door or windows while bored air is friven out.It can greatly imporve the unpleasant environment.The air change efficiency can reach 90%-97%. 

Characteristics:

1.Using stainless steel fan,big airflow,nice outlook.long lifespan,not deformation,not fractrue,not dusty.

2.Voltage of motor depends on customer's requirement.

3.Special water-proof design bearing,high quality,low noise,long lifespan,free maintenance.

4.Optional fan with auto-tight device belt,ensue belt work normally.

5.Optional swing heavy punch and centrifugal setting for fan swing.

Advantages:

1.Little cost,low somsumption.Compared with cooling efficiency air-conditioner,vacuum cooling fan is on-sixth in cost and one-tenth in comsumption.

2.Equipment with cooling pad high cooling efficiency.Temperature can be reduced to 28C which suitable with body tempreature.If it's well water,cooling efficiency will be better even can be compared to air-conditioner.

3.Fresh and clean air.Air cleanness can be up to 99%.
