When standard glass fiber media can’t stand up to aggressive or fire-resistant fluids like phosphate ester, Skydrol, or deionized water, Dynafuzz stainless fiber media offers a resilient alternative. Engineered to resist binder degradation, fiber migration, and media shedding in high temperature or acid environments, Dynafuzz maintains DFE-rated capture and retention performance under extreme conditions. Whether for turbine EHC systems, hydraulic controls, or power generation applications, Dynafuzz helps ensure reliability and fluid cleanliness where traditional media may fail.
EHC systems using phosphate ester fluids (FRFs) develop aggressive acids when exposed to water. The acid attacks glass fiber media binders of critical pump discharge and last chance servo pilot filters. Lower filter efficiency, media migration and fiber shedding into the servo screens can result causing servo valve malfunction. Dynafuzz media is DFE rated to provide the same low operating ISO Codes and contaminant retention you expect with the fluid compatibility you need.
Dynafuzz media is available for all Hy-Pro high collapse filter elements that are found in turbine EHC, primary metal, and other hydraulic control applications where fire resistant fluids are used. For the most critical installations (nuclear power), optional 100% bubble point integrity testing and validation is available. Part number modifier example, contact Hy-Pro for specifications and pricing:
The PFQ290218V Westinghouse EHC upgrade features a 3SF Dynafuzz media element (β4[c] ≥ 4000) in place of a 10 micron glass media element. The bowl extension with top loading element service minimizes mess and accepts a double length element allowing the use of higher efficiency media and extended element life.
