Negative Pressure Ventilation fan

Comparisons between Ventilation Facilities Ventilation Facilities Improvement after Using Negative Pressure Ventilation Fan Convection = Ventilation Effect: *5% 1. We use power exhaust coercively to cause air convection to reduce the dust and heat inside the factories. 2. After installment, air convection can improve the quality of atmosphere and lower the temperature inside as outside, even lower than outside. Besides, workers can also feel the wind floating. Furthermore, any places can have electricity-saving gear. 3. Especially, the places which are easier to bring dust, oil mist, waste gas, and heat can be improved over *5%.

Application Applicable to any place, especially the one with poor ventilation the generates heat, waste gas, soot and dust easily, which can achieve at least *5% imporvement.
