FILTER BAG MATERIAL & SIZE TOOL

Liquid Filter Bag Selection Guide

Compare PP, PE, NMO, PTFE, stainless-steel, and oil-absorbing bags, then verify standard size, reference flow, and differential-pressure limits.

INTERACTIVE FILTER BAG PRE-SELECTION

Build a material, rating, bag-size and construction brief in five steps

Filter-bag selection is not a temperature ranking. Media compatibility, filtration mechanism, micron rating, cleanability, and housing dimensions must be considered together.

Narrow the material range by process and maintenance needs
SELECT PRIMARY DUTY
PP

PP · Polypropylene

Needle felt · depth filtration
Temperature
Up to 90°C
Retention rating
Confirm grade and data sheet

Cost-effective for water, dilute acids/alkalis, and general industrial liquids.

Confirm oxidizers, solvent concentration, and actual operating temperature.

View product data
PE

PE · Polyester

Needle felt · depth filtration
Temperature
Up to 150°C
Retention rating
Confirm grade and data sheet

Higher temperature capability; commonly used for coatings, inks, oils, and selected solvents.

Strong alkalis and hydrolysis conditions require compatibility review.

View product data
NMO

NMO · Nylon Monofilament

Woven mesh · surface filtration
Temperature
Up to 190°C
Retention rating
Confirm grade and data sheet

Defined mesh opening, low fiber migration, washable and reusable.

Acidic media and fine-retention requirements need special review.

View product data
PTFE

PTFE · Polytetrafluoroethylene

Needle felt · severe service
Temperature
Up to 300°C
Retention rating
Confirm grade and data sheet

Broad chemical resistance for aggressive acids, alkalis, and compatible solvents.

Higher acquisition cost; seal and support materials must match the process.

SS

316L Stainless Steel

Woven wire mesh · surface filtration
Temperature
Process-dependent
Retention rating
Confirm grade and data sheet

High mechanical strength, cleanable construction, and resistance to abrasion.

Confirm corrosion compatibility, mesh construction, and sealing arrangement.

OIL

Oil-Absorbing Composite

PP melt-blown · particle + oil capture
Temperature
Up to 90°C
Retention rating
Confirm grade and data sheet

Combines particulate filtration with hydrocarbon absorption in water.

A functional specialty bag, not a universal replacement for ordinary felt bags.

COMPLETE PROCUREMENT CONFIGURATION
Preliminary recommendation: PP · Polypropylene Requested maximum temperature: 25 °C Design flow: 40 m³/h Target rating: 25 μm Bag size: #2, Ø180 × 810 mm Catalog reference flow: 40 m³/h (full test conditions unavailable; not guaranteed process capacity) Ring: PP molded ring Seam: thermal welded Catalog maximum ΔP reference: 2.5 bar Catalog change-out ΔP reference: 0.8–1.5 bar Status: engineering confirmation required; use the lowest applicable bag, housing and process limit.

Selection notice: this tool is for preliminary screening only. It does not replace media-compatibility confirmation, sample testing, or housing-dimension verification. For sizes #6–#7 and non-standard bags, provide an existing sample or dimensional drawing.

Filter bag data: what the references establish

Reference basis

The linked size/RFQ sheet is a summary derived from the JINLV liquid filter bag catalog. In this catalog, PE means polyester felt, not polyethylene. Confirm the exact media and construction on the quotation.

What is not established

Catalog temperature and differential-pressure references are not approval of every bag assembly. Ring, seam, support basket, liquid compatibility and housing limits must also be checked. A micron label alone does not establish absolute retention.

Before approval

Request the model-specific drawing, rating definition and available test documentation. Keep missing conditions marked “to be confirmed”; preliminary selector results are not an engineering approval.
