The Value Proposition Offered by HEPA Filtration
The cost of an E12 HEPA filter may be as much as four or five times the price of a conventional air filter. Economic analyses conducted by owners have typically focused on compressor performance and assumed a one- to two-year lifetime for HEPAs serving high-hours engines. Based on those parameters alone the HEPA was, and continues to be, a tough sell. But where the cost of replacement power is expensive or unavailable, water washing is not feasible, or a corrosive ambient environment is causing premature engine failure, HEPA filtration may be readily justified.

Use of Hydrophobic HEPA Filters May Double Time Between Aero-engine Overhauls
Alliance Pipeline conducted a four-year evaluation of Gore HEPA filters on LM2500 aerodynamic gas turbines serving two pumping stations in Canada. The short term benefits include virtually no degradation in compressor efficiency and shaft power over the run period and a better heat rate.

HEPA Filter Advantages Cited in Turbomachinery Article
James Ross of AAF says HEPA filter systems are lasting 80,000 hours. He recommends single stage reverse jet filters for pre filters. Mitsubishi has used HEPA filters for many years and they are widle used on Japanese gas turbines. Steve Medvetz of Gore says the High efficiency filter can eliminate water washing.

HEPA Air Filtration Technology Keeps Compressor Blades Clean
Combustion turbine operators generally experience turbine fouling from airborne particles passing through existing inlet air filters. Fouling can be caused by the particle capture limitations of conventional F-class (EN779:1998) or MERV-class (ASHRAE 52.2) filters. The consequence is reduced performance of the turbine operation.

HEPA an Alternative to Compressor Washing
About 10 manufacturers are actively pursuing GT owner/operators for their replacement filter business. But only W L Gore & Associates Inc, Elkton, Md, seems focused on HEPA filters at present. Perhaps the others believe the cost hurdle is too difficult to overcome: Turbine air filters often are considered a commodity with price the deciding factor in the selection process. Gore says its filter media offers a significantly lower pressure drop and longer effective lifetime than competitors’ products.
