Description / BorsoWound Big bleu

String wound Big blue filters are a popular choice when it comes to efficient and reliable water filtration. These filters are available in a variety of materials and lengths to suit different filtration needs. Let's delve into the materials and lengths available for string wound filters, helping you make an informed decision for your filtration requirements.


String wound filters are available in several materials, each with its own characteristics and applications. The commonly used materials include:

  1. Polypropylene (PP): Polypropylene string wound filters are widely used due to their excellent chemical resistance and compatibility with a broad range of liquids. They effectively capture sediment, sand, rust, and other particulates, ensuring cleaner water. The maximum temperature for polypropylene filters typically ranges from 80°C to 82°C
  2. Cotton: Cotton string wound filters provide exceptional filtration for applications where high levels of dirt-holding capacity are required. Cotton filters generally have a maximum temperature rating of around 120°C.
  3. Ryton: Ryton string wound filters offer superior resistance to chemical attack, making them suitable for challenging filtration environments. They are known for their durability and longevity in applications where aggressive chemicals or high temperatures are present. The maximum temperature for Ryton filters can range from 120°C to 150°C depending on the specific product.
  4. Nylon: Nylon string wound filters exhibit excellent mechanical strength and resistance to organic solvents. These filters are commonly used in applications where oil or hydrocarbons are present in the fluid being filtered. The maximum temperature for Nylon filters typically ranges from 60°C to 82°C.
  5. Fiberglass: Fiberglass string wound filters offer excellent durability and resistance to a wide range of chemicals and solvents, making them suitable for demanding filtration applications. In combination with a stainless steel core, they are heat-resistant up to 400°C (752°F).


Flow Rates:

The flow rates for Big Blue filters in 10 and 20-inch lengths may vary depending on factors such as the filter material, micron rating, and  pressure. As a general guideline,  flow rates per lenght are:

10-inch Big Blue Filter: The flow rate for a 10-inch Big Bleu filter typically ranges from 2.5 m3/hr 10 to 15 gallons per minute (GPM), depending on the specific filter cartridge and system conditions.

20-inch Big Blue Filter: The flow rate for a 20-inch Big Bleu filter is generally higher and can range from 5m3/hr  (15 to 20 GPM), depending on the filter cartridge and system conditions.
