Aegis® Classic Wound Elements
Stainless Steel Hardware
The original wound Powdex filter elements are constructed of polypropylene, nylon, or carbon fiber yarn wound around a stainless steel core with stainless steel end fittings. To insure product consistency the elements are manufactured with computer controlled winding machines. These elements are available in a variety of end fittings for Powdex® systems - Flanged double open ended, Sealfast™, or Ecoloc™ designs.

Aegis Classic Wound Elements
Polypropylene Hardware
The original wound Powdex filter elements are also available with polypropylene core and end fittings. Constructed with all polypropylene hardware, the elements can be crushed, incinerated or shredded for easy disposability. For 100% product consistency the elements are manufactured utilizing a computer controlled winding machine. These elements are available with a choice of polypropylene, nylon or carbon fiber outer windings and the variety of end fitting designs to fit the different Powdex systems.

Aegis ADDvantage™
The Aegis ADDvantage™ filter element is uniquely constructed with 100% polypropylene multi layer media that is absolute rated on the outer surface to prevent resin entrapment in the media matrix. The under layers are of an open pore construction. This permits free flow of purified condensate with minimum pressure drop and permits maximum backwash efficiency. A choice of polypropylene end fittings is available for easy installation into Powdex systems.

Aegis AFA®
For condensate systems that do not require resin precoats or systems that are precoated, the AFA or AFA 2000 filter elements will meet the demands of multi-backwashing without the loss of the filter’s ability to retain its integrity for retaining iron oxide particles. As with the DualGuard filters, the filter media is available in absolute ratings ranging from below 1.0 to over 20 microns. Like all Graver Technologies condensate filters, a variety of end fittings can be added to retrofit the elements in existing Powdex® systems or other condensate filter systems.

Aegis DualGuard™ I & II Filters
The DualGuard filter provides the advantage of pleated absolute rated filtration media for retaining iron particles and the outer retaining wrap allowing resin to coat evenly on the surface of the element without being lodged in-between the pleats. A selection of absolute rated filter media is available ranging from below 1.0 microns to over 20 microns. They
exhibit excellent mechanical strength for backwashing. The 100% plastic construction allows disposal by crushing, incineration or shredding.

Vessel Hardware
Several types of stainless steel hardware are available to secure filter elements in vessels. Full flow™ guide rods provide a rigid secure support for filter elements during operation or backwashing. In some vessel designs element installation or removal can be difficult. Graver Technologies’ engineers have solved this problem by designing a Full Flow Tilting Guide Rod which has made element replacement easier. A Quick Detach™ or Path Assembly™ seals the filter elements to the center support post. These assemblies are designed so that the spring seat cups and extension nut are one integral unit. Change out of filters, therefore, is quick and easy.

Captive Hitch Pin™
The loss or dropping of hitch pins during the installation of filter assemblies has been a concern for many utility operators. Graver Technologies’ innovative Captive Hitch Pin design eliminates these concerns by permanently attaching the pin to the extension nut. The loss or dropping of pins during installation is thereby eliminated.
