Product description
High efficiency polypropylene melt blown depth filter cartridge for industrial liquid filtration
The polypropylene melt blown depth filter cartridge – high efficiency is designed for applications requiring reliable, high-performance nominal filtration combined with long service life and low operating costs. Manufactured from 100% polypropylene using a controlled melt blown process, this cartridge delivers enhanced filtration efficiency while maintaining a low pressure drop.
The advanced fibre structure provides high dirt holding capacity and consistent filtration performance, making the cartridge suitable for continuous industrial liquid filtration duties across a wide range of process fluids.
Filtration principle
The cartridge is manufactured using a melt blown process that forms a true depth filtration structure with progressively varying pore sizes throughout the media.
-
Process liquid flows from the outside to the inside of the cartridge
-
Contaminants are captured throughout the full depth of the media
-
Larger particles are retained in the outer layers
-
Finer particles are captured closer to the core
This filtration principle provides:
-
high nominal filtration efficiency (approximately 95%)
-
excellent dirt holding capacity
-
low and stable pressure drop
-
extended service life
-
reliable performance under variable flow conditions
High efficiency depth media
The polypropylene melt blown media is engineered to provide enhanced filtration efficiency compared to standard depth cartridges.
Key characteristics include:
-
multi-density fibre structure
-
increased particle capture efficiency
-
high permeability for improved flow rates
-
consistent performance throughout service life
This balance between efficiency and flow makes the cartridge suitable for demanding industrial filtration applications.
Design and construction
The cartridge features a one-piece melt blown construction using thermally bonded polypropylene fibres without adhesives or binders.
Typical design features include:
-
single-layer melt blown polypropylene depth media
-
gradient pore structure for progressive contaminant capture
-
high porosity for reduced pressure drop
-
rigid construction for mechanical stability
-
binder-free media with low extractables
The design supports reliable operation under continuous flow and varying contaminant loads.
