Product Overview
PP Melt Blown Filter Cartridge 5 Micron 40 Inch is a mainstream precision depth filter in industrial melt-blown filter series. Adopting advanced melt-blown spinning and integral forming technology, pure polypropylene particles are melted and sprayed into a continuous fibrous filter layer without any binder or chemical glue, completely avoiding secondary contamination. The naturally formed gradient pore structure allows outer layers to trap large impurities and inner dense layers to intercept fine particles above 5μm, realizing full-depth pollution holding instead of single surface blocking. With standard 40-inch length, 60mm outer diameter and 30mm inner diameter, it is fully compatible with all mainstream 40-inch filter housings for plug-and-play replacement. Compared with 1μm ultra-fine melt-blown filters, it offers higher flow rate and lower pressure drop; compared with 10μm coarse filters, it provides more precise impurity removal, perfectly matching most standard industrial pre-filtration working conditions.
Working Principle
This 5 micron PP melt-blown filter cartridge operates on outside-in gradient depth filtration principle. When industrial process liquid flows through the multi-layer melt-blown fiber matrix, large sediment and rust scale are intercepted by the loose outer fiber layers; medium suspended particles are captured in the middle transition fiber area; fine micro impurities larger than 5μm are deeply trapped by the dense inner fiber layers. The layered interception structure evenly distributes contaminants inside the entire filter body, maximizing dirt holding capacity and effectively delaying filter clogging speed. The integral self-supporting structure maintains stable shape under continuous water pressure and flow fluctuation, ensuring consistent 5μm precision filtration effect during long-term 24-hour operation.

FAQ
Q1: What is the difference between 5μm and 1μm melt blown filters?
A1: The 5μm model has higher flow rate and larger dirt holding capacity, suitable for conventional industrial precision pre-filtration. The 1μm grade is for ultra-fine purification scenarios requiring stricter water quality standards.
Q2: Can 5μm melt blown filter be cleaned and reused?
A2: It is a disposable depth filter. Internal fiber pores are easily blocked by fine particles and colloids, and cleaning cannot restore original filtration performance, so repeated use is not recommended.
Q3: What liquids are suitable for this filter?
A3: It is widely applicable to neutral, weak acid and weak alkali industrial liquids, including process water, electroplating liquid, beverage liquid and conventional chemical reagents.
Q4: Are customized specifications available?
A4: Yes, full lengths (10/20/30/40 inch) and complete micron grades are available for bulk project orders.
