Non-Woven Filter Bags are widely used in various industries, including chemical, pharmaceutical, food and beverage, and wastewater treatment. Here are some common specifications for non-woven filter bags:
General Specifications- Material: Non-woven filter bags are made from various materials, including:
- Polypropylene (PP)
- Polyester (PET)
- Polyamide (PA)
- Polyethylene (PE)
- Filter Rating: The filter rating is the size of the particles that the filter bag is designed to capture, typically measured in microns (μm).
- Size: Non-woven filter bags come in various sizes, including:
- Diameter: 2-12 inches (50-300 mm)
- Length: 12-72 inches (300-1800 mm)
- Connection Type: Non-woven filter bags have different connection types, including:
- Ring top
- Gasket top
- Clamp ring
- Screw ring
Performance Specifications- Flow Rate: The flow rate of a non-woven filter bag is the volume of fluid that can pass through it per unit time, typically measured in gallons per minute (GPM) or liters per minute (LPM).
- Pressure Drop: The pressure drop is the difference in pressure between the inlet and outlet of the filter bag, typically measured in pounds per square inch (PSI) or bar.
- Temperature Range: Non-woven filter bags are designed to operate within a specific temperature range, typically between -20C to 150C (-4F to 302F).
Non-Woven Fabric Specifications- Fabric Weight: The weight of the non-woven fabric, typically measured in grams per square meter (GSM).
- Fabric Thickness: The thickness of the non-woven fabric, typically measured in millimeters (mm).
- Pore Size: The size of the pores in the non-woven fabric, typically measured in microns (μm).
Industry-Specific Specifications- Chemical Resistance: Non-woven filter bags used in chemical processing industries must be resistant to chemicals, such as acids, bases, and solvents.
- FDA Compliance: Non-woven filter bags used in food and beverage industries must comply with FDA regulations.
- ASME Compliance: Non-woven filter bags used in pressure vessel applications must comply with ASME standards.
