Key Features & Benefits
- High Filtration Precision: 50 micron nominal rating – effectively captures fine particles while maintaining high flow rates.
- Thermal Resistance: Continuous operation up to 150°C (302°F) – suitable for hot liquid filtration without degradation.
- Pressure Capability: Withstands differential pressure up to 1.0 MPa (145 psi) – robust for high-pressure systems.
- Needle-Punched Construction: Three-dimensional fiber matrix provides deep bed filtration, high dirt holding capacity, and low initial pressure drop.
- Chemical Compatibility: Polyester material resists weak acids, alkalis, and many organic solvents – ideal for diverse liquid applications.
- Customizable Dimensions: Available in various bag sizes, shapes, and seam types (sewn, welded) to fit your filter housing.
- Easy Installation & Replacement: Lightweight and flexible, with options for ring, snap-band, or strap top designs.
- Cost-Effective: Long service life and washable/reusable design (depending on application) reduces overall filtration cost.

Frequently Asked Questions (FAQ)
-
Can this filter bag be used for high-viscosity liquids?
Yes, the 50 micron rating and needle-punched structure allow for effective filtration of moderately viscous liquids. However, for extremely viscous fluids, we recommend consulting with our technical team to evaluate the best media and micron rating. -
What is the maximum temperature continuous?
The polyester material can operate continuously at 150°C. For short-term spikes up to 160°C, the bag may still function, but continuous use beyond 150°C is not recommended to avoid shrinkage or degradation. -
Is this bag washable and reusable?
Depending on the application and contaminant type, the bag can be washed (e.g., with water or mild detergent) and reused. However, repeated washing may reduce filtration efficiency over time. We recommend periodic replacement for optimal performance. -
Do you offer custom sizes or top styles?
Absolutely. We can manufacture bags in any length, diameter, or top style (ring, snap-band, strap, etc.). Please provide your filter housing dimensions and we will produce a tailored solution. -
What is the typical lead time for bulk orders?
For standard sizes, lead time is 7-15 days after order confirmation. For custom orders, it may be 15-20 days. We work efficiently to meet your schedule. -
Can I get a sample before placing a large order?
Yes, we offer free samples (excluding shipping cost) for evaluation. Contact our sales team to arrange a sample of your desired size and micron rating. -
Is this bag suitable for food contact applications?
Polyester is generally food-safe, but we recommend confirming specific regulatory requirements (e.g., FDA, EU) for your region. We can provide material compliance documentation upon request. -
What is the difference between needle-punched and woven filter cloth?
Needle-punched felt has a random fiber matrix that provides depth filtration, high dirt holding capacity, and lower pressure drop compared to woven cloth. Woven cloth is typically used for surface filtration and higher flow rates with larger particles.
