Matching the filter specifications to your system’s operating conditions ensures effective sediment removal, equipment protection, and process integrity. Our range of string-wound filters is designed to meet the needs of industries like water treatment, food and beverage processing, and chemical production.
Key Factors to Consider
Micron Ratings
Micron rating determines the particle size a filter can capture. Our filters range from 1 micron (fine filtration) to 100 microns (coarse filtration).Matching Micron Rating to Application:
- 1–10 Microns (Fine Filtration): Ideal for high-purity processes like pharmaceutical production or beverage filtration, removing fine sediment and silt.
- 10–50 Microns (General Filtration): Suitable for industrial applications like water purification and pump protection.
- 50–100 Microns (Coarse Filtration): Best for pre-filtration or systems requiring basic particle removal, such as wastewater treatment.
Choosing the correct micron rating ensures efficient operation without overloading downstream filters.
Filter Media
The choice of filter media impacts chemical compatibility, temperature resistance, and durability.Popular Media Options:
- Polypropylene: Excellent chemical resistance, suitable for water, solvents, oils, and mild alkaline solutions. Withstands temperatures up to 120°C.
- Cotton: Ideal for filtering edible oils and beverages, where natural fibers are required.
- Glass Fiber: Handles higher temperatures, making it suitable for aggressive fluids or high-temperature applications.
- Stainless Steel (Core Material): Provides mechanical strength for high-pressure applications.
Select the media based on fluid characteristics, temperature, and durability needs.
10 Micron vs. 50 Micron Filters
The choice between 10-micron and 50-micron filters depends on your application’s filtration precision and contaminant type.
10 Micron Filter:
- Applications: Removes fine sediment, suitable for drinking water pre-filtration, food and beverage processing, and light industrial use.
