Hot Melt Pocket Filter
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
Features
▸low resistance;
▸High filtration performance and dust holding capacity;
▸Long lasting;
▸High air volume;
▸The filter bag has high strength and is difficult to break or fall off;
▸Silicon-free design.

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.

QUESTIONS AND ANSWERS
Q1： Can You Cut Flat Before Rolling Up On The Paint Stop Filters?
A1： Most Of The Paint Stop Filters On The Market Are Cut Flat After Rolling Up Because It Is Very Easy Operate, There Will Be A Problem That The Edge Is Not Flat. Certainly, We Can Cut Flat Before Rolling Up, Which Can Be Up To 2.6m Wide.
Q2： How Did You Pack HEPA Filter?
A2： One Unit Is Packed With PE Bag Put In 5-layer Carton. If The Customer Is Worried About The Transportation Process, We Can According To The Requirements Of The Form Of Beating Bracket + Corner Protection + Wrapping Film Packing.
Q3： Have HEPA Filter Passed The DOP/PAO Leak Test?
A3： Sure, Our HEPA Filter Is 100% Able To Pass The PAO Test. Because We Will Do An Integrity Test Of Each HEPA Filter For Efficiency And Leakage Before Shipment And Provide A Corresponding Test Report. Any Leakage Will Be Regarded As Unqualified Products And Reworked. We Are Using MPPS Scan Test For HEPA Filter Integrity Test Which According To EN 1822 Standard.
The Scanning Tracks Will Cover The Area:
Inside Filter Material, Sealant, Filter Frame, Corners, Gasket, Seal Of The Filter Mounting Assembly, The Sealant Between Filter Frame And The Gasket
Q4： How Long Does It Usually Take For Me To Receive The Goods?
A4： Depends On Whether You Want To Do Customization Your Air Filters Or Not, And Depends On The Speed Of Customs Clearance And Logistics, But We Can Guarantee To Ship Regular Air Filter In Less Than 7-10 Business Days, And We Have Customers In Singapore Who Received The Goods In Less Than 2 Weeks After We Ship Out.
