380V 1.1kw Negative Air Fan Negative Pressure Window Fan CAD/CAM

380V Galvanized negative pressure fan 1270mm 1.1kw
Pressure Fans Feature:
Effective Ventilation and Heat Removal: In environments where heat sources like sunlight, machinery, and human bodies cause indoor temperatures to rise above outdoor levels, negative pressure fans provide essential ventilation. They rapidly exhaust hot air from the building, effectively equalizing the indoor and outdoor temperatures and preventing heat buildup within the workspace.
Natural Cooling Effect: By promoting air circulation, negative pressure fans create a cooling sensation similar to a natural breeze. The moving air carries away heat from the human body and accelerates the evaporation of sweat, resulting in a noticeable cooling effect. This makes the environment more comfortable and helps prevent heat stress among workers.
Important Clarification: No Refrigeration: It's essential to understand that negative pressure fans primarily provide ventilation and a cooling sensation. They do not have a refrigeration function and cannot actively lower the air temperature below the ambient outdoor temperature. Claims about negative pressure fans "reducing the temperature by a certain number of degrees" are misleading and inaccurate. The cooling effect is solely based on the movement of air and its impact on the human body's perception of temperature.
Enhanced Cooling with Evaporative Cooling Pads: When used in conjunction with evaporative cooling pads (wet curtains), negative pressure fans can significantly enhance the cooling effect, especially during the hottest summer months. This combination can effectively maintain indoor temperatures below 28°C (82°F). While this provides a considerable improvement in comfort, it's important to note that the cooling sensation is different from that of air conditioning. Prolonged exposure to the cool, humid air generated by evaporative cooling pads can sometimes lead to a feeling of being chilled.
