  JHCOOL VACUUM COOLING FAN/ Exhaust fan:

Introduction of Vacuum Cooling Fan:

Vacuum cooling fan is based on the theorycross ventilation and vacuum air change. Fresh air comes from door or windowswhile bored air is driven out. It can greatly improve the unpleasantenvironment. The air change efficiency can reach 90%-97%.

Characteristics:

1. Usingstainless steel fan, big airflow, nice outlook, long lifespan, not deformation,not fracture, not dusty.

2. Voltageof motor depends on customer’s requirement.

3. Specialwater-proof design bearing, high quality, low noise, long lifespan, freemaintenance.

4. Optionalfan with auto-tight device belt, ensure belt work normally.

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

Advantages:

1. Littlecost, low consumption. Compared with cooling efficiency air-conditioner, vacuumcooling fan is one-sixth in cost and one-tenth in consumption.

2. Equipmentwith cooling pad High cooling efficiency. Temperature can be reduced to 28°C whichsuitable with body temperature. If it's well water, cooling efficiency will bebetter even can be compared to air-conditioner.

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