Facility PP Melt-blown UPW Filter

Product ID: facility-pp-melt-blown-filter-upw|Facility UPW

High-efficiency PP melt-blown filter element designed specifically for industrial filtration. Made of 100% pure polypropylene and a unique three-layer gradient pore design, it has high porosity and excellent dirt holding capacity. Various surface treatments such as grooves, embossing, and orange peel are available to increase the filtration area. Resistant to strong acids, alkalis and organic solvents, it is the economical first choice for RO pre-filtration, factory wastewater and chemical processes.

Specifications

Filter media / membrane: Fibre spun from 100 % virgin polypropylene resin and thermally entangled with no binder of any kind. A three-layer graded pore design gives a three-dimensional depth effect — high porosity, high dirt-holding capacity and low pressure drop.
Support & drainage layers: No separate support layer; an optional polypropylene core stiffens the structure
Cage, core & end caps: Polypropylene adapters and end caps, with an optional polypropylene core. Inner-bore heat treatment together with the core prevents fibre shedding.
Seals / O-rings: None (flat gasket) / silicone / EPDM / FKM / NBR
Micron rating: 0.1 µm / 0.5 µm / 1 µm / 3 µm / 5 µm / 10 µm / 20 µm / 25 µm / 30 µm / 50 µm / 70 µm / 100 µm
Removal efficiency: Even void distribution for high efficiency; plain, grooved, embossed, orange-peel and lofted (high-capacity) surfaces are available to add area, giving roughly twice the service life of a conventional melt-blown cartridge.
Nominal outer diameter: Ø64 mm
Nominal lengths: 5" / 10" / 20" / 30" / 40" / 60" / 70"
End cap / connection: Double open end flat gasket / 222 flat / 222 fin / 226 flat / 226 fin
Max operating temperature: < 82 °C; pH 1–13
Max forward differential pressure: 3.5 bar @ 20 °C; 1.0 bar @ 82 °C
Extractables & cleanliness: All-polypropylene and binder-free, with very broad chemical compatibility for strong acids, strong alkalis and solvents.

Note: actual compatibility and service life depend on chemical concentration, temperature, flow, differential pressure, upstream contamination load and housing design. Validate under your real process conditions.

Flow vs. Differential Pressure

Water at 25 °C, single 10" cartridge, clean initial ΔP　Right axis shows the same values in psi.

The 75 µm and 100 µm curves are effectively coincident with 50 µm. For cartridges of 20" and longer, ΔP at the same total flow falls in proportion to length.

Details

Where it fits

Process position.Economical high-flow pre-filtration on the facility side: pre-RO duty, facility recirculation water, wastewater treatment and upstream chemical processes. The brief is "reliably capture large particles at the lowest cost", not fine filtration.

Three-layer graded pore structure

Key characteristics

Key features.Pore size decreases across three layers from outside in, capturing particles in size-appropriate layers and giving markedly higher dirt-holding than single-density melt-blown media.

Surface treatment for added area

Grooved, embossed and orange-peel surface treatments are available. At the same outer diameter, surface treatment increases effective filtration area, lowering initial pressure drop and extending change-out intervals.

100% virgin PP

Made from 100% virgin polypropylene, resistant to strong acids, strong alkalis and organic solvents across a broad range of duties.

Lowest cost

The lowest unit price of all the pre-filtration options, suited to facility applications with stable feed water and low change-out cost.

Choosing between options

When to upgrade.

Situation	Recommendation	Why
Change-outs too frequent, downtime expensive	Move to JY-UW31 rolled	Around 3× the dirt-holding and life, lower total cost of ownership
Too many cartridges, change-out takes too long	Move to JY-UW32 high-flow	Cartridge count drops ~90%, change-out labour falls sharply
Semiconductor-grade low extractables needed	Move to JY-UW33 electronic-grade PP	Adhesive-free, low extractables, fast conductivity recovery
30nm fine filtration needed	Move to JY-UW11 asymmetric PES	Membrane fine filtration, a viable UF alternative

FAQ

Why are there multiple surface treatments?

Grooved, embossed and orange-peel surface options are offered to increase the effective filtration area, raising dirt-holding capacity and extending service life.

Can it withstand chemicals?

Yes. Made from 100% pure polypropylene, it resists strong acids, alkalis and organic solvents, suiting demanding facility wastewater and chemical process conditions.

Is it suitable for RO pre-filtration?

Absolutely. Its three-layer gradient pore design offers high porosity and excellent dirt-holding capacity, making it an economical choice for RO pre-filtration, facility wastewater and chemical processes.
