KESBO low-noise vacuum blower series products are used CAD/CAM design, with less investment, significant ventilation and cooling effect, high full pressure, large air flow, low noise, small energy consumption, smooth operation, long life characteristics, and unique automatic switch device of blinds do not use power, turning the power, but to use the weight balance, and this unique system can guarantee there will be many years of operation without problems, and it’s also dust-proof, waterproof, beautiful and generous. Therefore, it is the best choice for modern plant cooling ventilation. By negative pressure ventilation, and then using super suction to make indoor and outdoor air exchange, so that the indoor heat, smell, dirty air will exhaust while natural fresh air flowing. 1 minute: can exhaust emissions, sewage gas from a factory (150m),change into a fresh air fully. 10minutes: can rapidly decrease the temperature inside the plant within 10 minutes (32-45 °C high temperature environment), and the temperature maintains at 26-30 °C Only 20% air-condition cost: KESBO Fan Cooling system can realize decrease temperature and ventilated function, only need 20% air-condition consumption, it is a really money saving professor for factory. According to the actual situation in plants, KESBO low-noise vacuum blower calculates the required air changes, ventilation volume per hour, to give priority to configure to effectively solve high-temperature and hot air pollution.
