EPA E11 filter cartridge for gas turbines

Specifically designed to significantly reduce compressor fouling and water washes for gas turbines, HydroShield cartridges offer an outstanding combination of filtration efficiency, low cost of operation, and filter life.

The EPA E11 grade filtration of the HydroShield filter protects against corrosion, increases gas turbine availability and lowers operating expenditure. It helps prevent lost power due to compressor fouling, increases fuel efficiency and improves engine reliability. The accumulative effect is a reduced total cost of ownership resulting in operational peace of mind.

Features & Benefits

  • With an initial efficiency of >95 % at the most penetrating particle size, HydroShield ensures maximum available power output by maintaining compressor cleanliness.
  • HydroShield’s EPA E11 cartridges utilize a proprietary media that is both oil and water resistant.
  • Water washing intervals are extended, reducing downtime and maintenance shutdowns.
  • Low pressure drop, resulting in higher power output and lower fuel consumption.
Case Study

AAF’s HydroShield restores compressor efficiency

The site in question operated two 195 MW GE Frame 7FA gas turbines that were being operated in a power generation application. The units were in New York, next to several sources of air contamination, which resulted in a compressor efficiency decrease of approximately 3.9% over six months. AAF upgraded the existing F9 cartridges to HydroShield EPA E11. Find out more...
