Description
Construction
Hot melt bag filters usually use a bag structure to ensure that the air flow is evenly distributed throughout the bag. The design includes multiple layers of filter materials, such as coarse fiber filter cotton, fine fiber filter paper, and a protective layer, to achieve step-by-step filtration and improve filtration accuracy and service life. In addition, the design of the bag support grille prevents the bag from shrinking or bending out of shape in harsh environments, further enhancing the reliability of the device

Application
The hot melt bag filter has a high filtration efficiency, such as the removal efficiency of ≥1.0μm particles can reach more than 80%.
It is suitable for a variety of environments, including wet, high airflow and dust loads, and is widely used in pharmaceutical, automotive, food manufacturing, commercial buildings, and industrial ventilation systems

Hot Melt Blanking Process of Air Filter Bag
Under the high temperature condition of 65- 200 °C, the edge of the filter bag is hot melt pressed together by using a high frequency heat conduction plate. The filter bag material is: polyester fiber mixed with low melting point polyester fiber. Through high frequency hot melt, the edge of the filter bag can be perfectly fused together, so that the product is firmly bonded, no pollution to the filtered material, stable purification efficiency, dust removal effect of 100%; The edge sealing effect is good, the dust capacity increases, thus extending the original one month replacement time to about 2-3 months. The function of hot melt welt pressing is to hot melt the edge of the filter bag according to the content of low melting point polyester fiber in different materials, and use the relative hot melt temperature to hot melt the edge of the filter bag, so that the filter efficiency is improved, the dust capacity is increased, and the overall beauty is improved.
