Air filter standard, high efficiency air filter, primary filter, Xingmao filter

Xingmao air filter is mainly used to capture dust particles and various suspended solids. It uses ultra-fine glass fiber paper as the filter material, offset paper, aluminum film and other materials as the dividing board, and is glued with the wooden frame aluminum alloy. Each unit has been tested by the Nafeng method and has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity. It is widely used in various local purification equipment and clean workshops to purify ambient air under normal temperature, normal humidity, and normal pressure conditions. It can be washed and used repeatedly, has a long service life, and is cost-effective. It is generally used for primary filtration of central air conditioners and household air conditioners. It is a special acid- and alkali-resistant ventilation filtration. It is suitable for the primary filtration of air conditioning systems. It is mainly used to filter the above dust particles. Air filters are available in three styles: plate type, folding type, and bag type.
Each Xingmao air filter has been tested by the Nafeng method. It has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity. It is widely used in various local purification equipment and clean workshops at normal temperature, normal humidity, Purification of ambient air under normal pressure conditions. Medium-efficiency filters are widely used in central air-conditioning ventilation systems, electronics, food and other industrial purification. They can also be used as front-end filtration of high-efficiency air filters to pass water with higher turbidity through a certain thickness of granular or Non-granular materials, thereby effectively removing suspended impurities and clarifying the water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment to remove turbidity, soften water, and pre-treatment of pure water. The turbidity of the effluent can reach below 10°C. It uses ultra-fine glass fiber paper as the filter material, offset paper, aluminum film and other materials as the dividing board, and is glued with the wooden frame aluminum alloy. Each unit has been tested by the flame method and has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity.
