The PP folding filter element adopts a folding type, with a large filtering area, large pollutant capacity, low pressure difference, and long service life. The overall filter element is made of 100% pure PP material, which has wide chemical compatibility.
PP melt blown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles, which are heated, melted, sprayed, pulled, and formed. This filter element is not only widely used in the water purification industry, but also has outstanding chemical compatibility, suitable for filtering strong acids, bases, and organic solvents.
Difference:
1. Filtering efficiency
The folding filter element is made up of multiple layers of filter materials, which can effectively filter out smaller particles and improve filtration efficiency. Although melt blown can also be used to manufacture filter materials, its filtration efficiency is relatively low due to the coarser fibers of the non-woven fabric it produces.
2. Service life
The multi-layer material design of the folding filter element also extends its service life, reducing the frequency and cost of replacing the filter element. However, non-woven fabrics produced by melt blown manufacturing are prone to damage and wear due to their thicker fibers, resulting in a shorter service life.
3. Application field
Folding filter cartridges are widely used in high-end fields such as healthcare and air purification, with high technical barriers and costs; Melt spraying, on the other hand, focuses on low cost and high efficiency, and is suitable for the manufacturing of some industrial and daily life fields, such as masks, cleaning products, etc.
