COAX™ Melt Blown filter cartridge

Two Stage Depth filter cartridge

The COAX Depth Filter cartridge is an integral two stage depth filter. The first stage of the filter cartridge is made of non-woven melt blown polypropylene to trap coarser articles.

The second stage inner core is composed of a bi-component polypropylene and polyethylene fibre to provide fine particle retention. This unique design provides a true graded density filter cartridge that offers a marked increase in useful life and dirt capacity.

In addition, the rigid nature means there is no flexing of the cartridge and greatly reducing media migration and particle unloading.

Filter Features–Benefits

  • Two stage graded density melt blown depth filter helps to Maximize dirt holding and useful life
  • Inert pure polyolefin construction, non-shedding media
  • Broad chemical compatibility
  • Low extractables
  • Meets USP Class VI standards – Acceptable for use in food, beverage and pharmaceutical applications
