BOS Gradient Filter Bags

Summary

Product Identification

The BOS Gradient Filter Bag is a seamless, absolute-rated filter element made from 100% polypropylene microfiber. It is designed to combine the depth filtration benefits of a cartridge with the convenience of a bag.

Key Features

• Gradient Density Design:
  • Provides up to 18 times extended life compared to other products (depending on particle distribution and application).
  • Leads to fewer bag changes, reducing labor costs and product loss.
  • Not compressible in operation, ensuring greater dirt holding capacity.
  • Designed for broad particle distribution applications.
  • Allows for more efficient (lower micron) filtration without sacrificing product life.
• Polypropylene Microfiber Material:
  • Adsorbs up to 16 times its own weight in hydrocarbons (oils).
  • Can reduce inventory by eliminating the need for separate "oil" bags.
  • Thermally bonded, with no lubricants or surface active agents.
  • Available with NSF Standard 61 Certification.
• Seamless Construction: Ensures integrity and performance.
• Compatibility: Fits existing FSI standard baskets, avoiding retrofit costs.
• Bonding: Features a thermally bonded ring.

Material Properties (Polypropylene)

As a 100% polypropylene microfiber product, the filter exhibits the following general chemical resistance:

• Weak Acids: Excellent
• Strong Acids: Excellent
• Weak Alkali: Excellent
• Strong Alkali: Excellent
• Solvents: Fair

Note: Product-specific operating temperature limits take precedence over general material properties.
