BOS Gradient Filter element is the first of its kind, with seamless design and true gradient density. This absolute rated element provides users with the depth of a cartridge and the convenience of a bag. This 100% polypropylene microfiber product adsorbs up to 16 times its own weight in hydrocarbons (oils) and will last up to 18 times the life of other products (depending on particle distribution and application).

Features / Benefits
Gradient Density provides:
   Up to 18 times extended life compared to other products, dependent upon particle distribution and application
   Longer life means fewer bag changes which results in lower labor costs and less loss of product
   Not compressible in operation providing greater dirt holding capacity
   Designed for typical broad particle distribution applications.
   Will allow more efficient filtration (lower micron) without sacrificing product life
