Product description
Nominal rated nylon melt blown depth filter cartridge for economical liquid filtration
The nylon melt blown depth filter cartridge – nominal is engineered for general industrial and process filtration applications where reliable particulate removal, high dirt holding capacity and broad chemical compatibility are important. Manufactured from thermally bonded nylon fibres using a melt blown process, this cartridge offers a cost-effective solution for nominal depth filtration.
The gradient density construction captures contaminants throughout the media depth, providing excellent service life and predictable filtration behaviour in a wide range of fluid environments.
Filtration principle
The cartridge utilises a melt blown nylon media with a controlled gradient density structure, where coarser fibres on the outside transition to finer fibres toward the inner core. This design maximises available filtration area and enables progressive contaminant capture.
Process liquid flows from the outside of the cartridge to the inside, allowing particles to be retained throughout the depth of the media according to the nominal micron rating.
This filtration principle provides:
-
nominal particle retention
-
high dirt holding capacity
-
stable low differential pressure
-
predictable and repeatable performance
-
suitable performance across variable flow conditions
Nominal filtration ratings are optimized for general sediment and particulate control rather than defined absolute retention.
Media technology and uniqueness
The filter media consists of melt blown nylon fibres thermally bonded to form a depth filter matrix. Nylon is selected for its mechanical strength, thermal stability and compatibility with a wide range of process liquids.
Key media characteristics include:
-
nylon melt blown depth media
-
gradient density structure for depth filtration
-
high porosity for improved flow rates
-
excellent chemical compatibility
This construction delivers economical filtration performance with extended service intervals.
Design and construction
The cartridge features a continuous melt blown nylon media supported by a rigid internal core. The media is thermally bonded, eliminating the use of adhesives or binders and minimizing extractables.
Typical design features include:
-
gradient density melt blown media
-
thermally bonded construction for media integrity
-
rigid internal support core
-
robust design for general filtration duties
The cartridge is designed for installation in standard industrial filter housings.
