What is a PP melt blown filter cartridge?

PP melt blown filter cartridge is constructed by 100% pure polypropylene fiber, providing wide chemical compatibility. With innovative and advanced graded pore structure, it can provide effective particle retention.

Brother Filtration utilizes 3 layered construction for progressive contaminant removal efficiency. Our filter media contains no binder, glue, or any other additives, just pure PP structure.

With years of experience, we are able to custom special PP melt blown cartridge filters with varied specifications like groove, orange peel, and hairy surface finish or equipped with different SOE/DOE end caps for you.

Characteristics of precision filter

For Melt Blown Filter, we usually offer the removing ratings of 1, 3, 5, 10, 20, 30, 50, and 100um. The outer diameter is 63mm or 113mm. The inner diameter is 28mm or 30mm. The length usually is from 10 inch to 70 inch.

The O-ring is made up of silicon, EPDM, Viton, and Nitrile. If the liquid has characteristics of strong acid and alkali, the O-ring should be made with Viton, which could avoid the acid and alkali to get a chemical reaction. If the liquid is oil type, the O-ring should use Nitrile.

For Melt Blown Filter, there are two types for the ends, one is the double open end(DOE), and the another is the single open end. For the second one, both ends could be made up of 4 types, which are 222/flat, 226/flat, 222/fin, and 226/fin.

How is the melt blown made?

The main filter element in melt blown filter cartridge is as its name, melt blown. Melt blown is made by extrusion technology. Heating the machine and putting in the raw materials, the filter element is produced according to the mold. Based on the size you want, the machine cuts the filter element.

The problem with melt blown filter cartridge

We have many clients who complained about their former melt-blown filter cartridges and former supplier. Because the instability of the melt blown filter cartridge leads to many filtration problems and affects the filtration performance.

That is caused by the production machine, when the manufacturer doesn’t pay attention to the regular clean for the machine, the extrusion machine can be clogged, resulting in the instability of the filter cartridge.

Why some manufacturers are not willing to shut down the machines and have regular maintenance and clean. It is obvious that they want to save costs.
