"Tiny Cooling Fan" has a strong advantage, invest less cooling effect, after the start, so that the original workshop temperature is 40-45 degrees ambient temperature decreased rapidly and stabilized at between 25-30 degrees Celsius. Fresh air ventilation rate of 98%. Roof fan is good ventilation. "Tiny Cooling Fan" dependent on natural wind, reduce the amount of unnecessary trouble because the circuit circuit or fire, etc. caused by work overload. High sensitivity, all-weather operation, to achieve good exhaust ventilation purposes. Also has the advantages of low noise. Fiberglass material, long life. "Tiny Cooling Fan" generate air convection, heat bulk gas, reduce air conditioning load, increase the indoor fresh air. Out moisture, Mei Qi, steam, keep dry. Cost savings, low noise. Arguably the best ventilation equipment factories, warehouses, rooftops, farms.
