PP Melt Blown Filter Cartridge 1 Micron 40 Inch: Depth Melt Blown Polypropylene Filter For Ultra-Fine Liquid Pretreatment
Introduction:If you are sourcing PP Melt Blown Filter Cartridge 1 Micron 40 Inch for ultra-fine industrial liquid filtration and ultra-pure water pretreatment, this gradient depth filter is manufactured by melt-blown virgin polypropylene without additional binders. It can reliably trap micro suspended solids, tiny colloids and fine silt particles above 1 micron. The gradient pore structure with loose outer layer and dense inner layer provides excellent dirt holding capacity, which helps reduce the fouling risk of RO and UF membrane systems. This disposable filter cartridge features low pressure drop and stable filtration performance. It is widely used in semiconductor ultra-pure water, pharmaceutical auxiliary water, fine chemical liquid clarification and high-standard electroplating solution filtration projects for global industrial water treatment systems.

Product Overview
PP Melt Blown Filter Cartridge 1 Micron 40 Inch is a classic depth filter made from pure polypropylene via melt-blown one-step forming process. No glue or adhesive is added during production, avoiding secondary contamination caused by organic dissolution. The unique gradient pore structure is formed naturally during melt-blown molding. The outer layer has larger pores to capture big impurities, while inner tiny pores intercept micro particles. Standard size is 40 inch length, 60mm outer diameter and 30mm inner diameter, compatible with all standard 40-inch filter housings for quick replacement. Compared with 1μm pleated PP filter, melt blown cartridge belongs to depth filtration rather than surface filtration, and can hold more contaminant inside the whole filter body. Virgin PP material delivers good resistance to weak acid and weak alkali, suitable for most neutral and mildly corrosive liquid working conditions.
Working Principle
PP Melt Blown Filter Cartridge 1 Micron 40 Inch adopts outside-in gradient depth filtration principle. When process liquid flows through the melt-blown PP matrix, coarse contaminants are captured in the outer loose layer. Medium particles are trapped in the middle section. Micro particles larger than 1 micron are intercepted inside the dense inner layer. Instead of blocking only on the surface, pollutants are stored inside the whole filter body, greatly extending service life. The integrated one-piece structure prevents liquid bypass. The self-supporting melt-blown body maintains shape under differential pressure and ensures stable continuous filtration performance for 24-hour running.

FAQ
Q1: What is the difference between 1μm melt blown filter and 1μm pleated PP filter?
A1: Melt blown filter is depth filtration with bigger dirt holding capacity, pollutants are trapped inside the filter body. Pleated PP filter relies on surface filtration with larger flow rate. Both are disposable.
Q2: Can this 1μm melt blown filter be cleaned and reused?
A2: It is disposable. Once inner pores are blocked by colloids or fine particles, washing cannot restore original filtration performance.
Q3: What is the maximum continuous operating temperature?
A3: Continuous working temperature cannot exceed 60℃. High temperature will soften and deform polypropylene melt-blown structure.
Q4: Can custom specifications be arranged for bulk orders?
A4: Yes, 10/20/30/40 inch lengths and various micron ratings can be customized for large projects.
