In recent days, some northern regions such as Beijing Tianjin Hebei have experienced the first large-scale haze weather since the beginning of autumn. It is expected that the northern region will continue to experience heavy haze weather in the next two days. The haze will gradually dissipate when a cold air arrives tomorrow night. Urgent measures have been taken in various regions to respond. Long term treatment of haze has yielded no results, can we be self-sufficient? The medium efficiency filter is mainly used for removing and preventing haze.
The original intention of designing medium efficiency filters is to ensure the necessary clean air for production. With the development of technology, in recent years, the air in the spaces where we live has been severely polluted, posing an invisible and visible threat. We dare not open the window for ventilation! The high-efficiency air filter in junior high school plays an important role in air purification.
The medium efficiency filter is made of non-woven fabric composed of organic synthetic fibers and microfibers, presenting a fiber-reinforced structure that can filter filter filter bags with excellent performance and no biological activity, ensuring that PM1 and microorganisms cannot grow. And the filter bag containing electrostatic fibers has higher dust capture ability and higher ventilation capacity. Taking the 595 * 595 * 600 medium efficiency filter as an example, it is divided into 6 filter bags, each with six partitions evenly distributed in the bag width to prevent the filter bags from expanding excessively with wind pressure and covering each other, thereby reducing the effective filtration area and efficiency. And the medium efficiency filters produced by Tianjin Klien Air Filter Factory are fixed with metal strips between each filter bag to increase the strength of the filter screen and prevent the filter bag from breaking due to frictional force caused by wind shear at high wind speeds. Please refer to the table below for common specifications of medium efficiency filters:
