The 50 micron filter bag is a liquid filtration consumable designed to intercept particles of 50 microns (μm) and above. Usually made of polypropylene (PP), polyester fiber (PET), non-woven fabrics, nylon and other materials, through the precision weaving or heat fusion process to form a stable three-dimensional filtration structure, can be adapted to single bag or multi-bag filters, to meet the filtration needs of industrial water treatment, municipal and food and pharmaceutical filtration needs in the field.
Precise Filtration Performance
Nominal precision of 50 μm: precision error ≤±5% through laser aperture detection, interception efficiency ≥99%. It can efficiently intercept solid particles of ≥50μm to ensure the safety of downstream equipment and product quality.
01
Multi-layer Filtration Mechanism
Surface filtration (e.g. nylon monofilament weaving): large particles are directly intercepted and can be repeatedly cleaned and used.
Deep adsorption (e.g. non-woven fabric): three-dimensional fiber structure adsorbs fine impurities with a dirt-holding capacity of up to 500 g/m².
02
Diversity Of Materials
Material selection: PP (polypropylene), PET (polyester) or nylon, etc., acid and alkali resistance, corrosion resistance, suitable for strong chemical environments; stainless steel or galvanized bag mouth ring to enhance tensile strength and prevent deformation.
03
Structural Design
Bag structure: seamless hot melt process, no risk of side leakage; standard stainless steel support ring, tensile strength ≥800N/5cm, suitable for high pressure system (1.0MPa).
04
Flexible Adaptability
Standard size: supports universal specifications such as 1# (180×420mm), 2# (180×810mm), and adapts to more than 90% of filter models in the market.

| Challenge | A specialty chemical producer struggled with recurring downtime in their wastewater recovery unit. Corrosive byproducts and undissolved polymer flakes (<80 microns) were bypassing existing screens, degrading RO membranes within weeks. |
| Solution | After trialing multiple mesh sizes, engineers implemented a dual-stage filtration system using 50-micron polypropylene filter bags as the primary barrier. |
| Result | 1. Post-installation lab tests confirmed a 68% drop in suspended solids, extending membrane replacement intervals from 3 to 14 months. 2. The plant now avoids €18,000/year in unplanned shutdowns and chemical cleaning expenses. |
1. Installation Specifications
Ensure that the filter bag fits snugly against the inner wall of the filter to avoid bypassing unfiltered liquids.
Pre-wetting the filter bag can improve the initial filtration efficiency (especially for high viscosity liquids).
2. Replacement intervals
Replace the filter bag when the differential pressure reaches 0.1MPa or when the flow rate drops significantly.
Shorter replacement intervals are recommended for corrosive liquids.
3. Disposal
Dispose of the filter bag according to environmental regulations, some materials can be incinerated or recycled.
