DualGuard® I Polishing Septa

DualGuard I elements are engineered for systems that require a uniform precoat on the outer surface of the septa.

Graver Technologies DualGuard I elements are engineered for systems that require a uniform precoat on the outer surface of the septa, providing an effective removal of iron oxide particles while still allowing for an effective backwash. The all polypropylene constructed element has two distinct zones. The outer zone is a multi-string wound surface ideal for precoating in either a thin or a full layer resin precoat and the inner zone is a pleated polypropylene with a fixed pore media. The inner pleated filter media is available in a variety of micron grades to meet specific requirements of the condensate system. The element is available in most end cap connections.

  • Precoatable with a full or thin layer of powdered resin
  • Available in various outside diameters
  • Fixed pore construction eliminates dirt unloading as differential pressure increases
  • High surface area of pleated media
