1. Air outlet surfaces: On the seal ring and in the installation point, polyurethane foam sealing agent (double-ingredient polyurethane PU glue) is applied to bond filter paper for sealing.
2. Filter paper: mainly for intercepting and filtering impurities.
3. Air inlet surfaces: The binder (PO) ensures airtightness between filter paper pieces.
PU glue provides good sealing when a vika filter element is loaded into an enclosure. The required Shore hardness for the PU glue is 25±3. In contrast, in products of other brands, air leakage may occur due to inadequate foaming.
Filter paper bonding: After the paper is folded, the hot melt glue should be applied evenly on both sides. Bonding should be completed in the time period corresponding to optimum status of the glue (3S).
