Fuzhou Environmental Protection Equipment Co., Ltd. has specialized harmonic development team and strong technical force. Professional production plant cooling equipment, plant cooling equipment, plant ventilation equipment, workshop ventilation equipment, is a collection development, production, sales and service in one of the enterprises. The company's product technology in a leading position in the introduction of foreign advanced technology developed on the basis of high-tech innovative products more suitable for domestic use. Products to market over the years, by domestic customers the unanimous recognition. Company to conserve energy for the purpose of self-development and production of suction fan, water conditioning is widely used in plastic injection molding, metal casting, textiles and garments, electroplating, footwear and other industrial production workshop. We are committed to improving the environmental pollution to human discomfort, with high-tech efficiency, give full play to their strengths, to create a better environment for the good of mankind. Suction fan, water conditioning can fully reflects the high efficiency, low energy, environmental protection, cost, wide range of other top-five advantage, has become the brand of choice for many enterprises ventilation. Negative pressure is to allow air convection in the workshop, but is needed is a process of energy conversion. Suction fan is converted into kinetic energy (wind) in electricity-driven, the bad (odor, heat, dust) the rapid discharge of indoor outdoor, so that the pressure is lower than the indoor outdoor, while under the influence of atmospheric pressure, the outdoor fresh rapid inflow of indoor air from the installation windows opposite negative pressure exhaust fan, ventilation frequency of up to 60 times per hour (100 square meters workshop), thus creating a comfortable working environment air fresh and clean. Maybe you put a lot of expense to do to improve, the number of the ceiling fan, fan relay, horn fan can not change the status quo, it is because they let the heat cycle in the workshop, so that you reach the desired effect. In the hot summer workshop temperature is higher than outdoor 5 ~ 10 ℃, Gu was unable natural ventilation simultaneously plus sun room temperature can not be lowered. Cool wind suction horn fan indoor temperature can be decreased rapidly and convection, while increasing the oxygen content of air, which are comfortably cool.
