The Medium-Efficiency Air Filter for Salt Spray Removal is a specialized filtration solution designed to capture salt aerosols, coastal mist, and corrosive airborne particles in harsh marine and industrial environments. With an F7-F9 efficiency rating (EN 779:2012), it serves as a cost-effective pre-filter or standalone solution for applications where high-efficiency HEPA filters are unnecessary but salt corrosion protection is critical.

What is corrosion?
Gas Turbine engine performance degradation is classified as either recoverable or non-recoverable. Recoverable performance degradation is usually due to compressor fouling and can normally be overcome by online and offline water washing. Non-recoverable performance degradation is usually caused by rotating internal engine part wear, as well as plugging of cooling channels, erosion & corrosion due to contaminants in the air, fuel and / or water.
Ingested contaminants can result in corrosion of the compressor, combustor and turbine sections of a gas turbine engine. Hot corrosion is the most serious form of corrosion experienced in the turbine section. It is a form of accelerated oxidation that is produced between components and molten salts deposited on its surface. Sodium sulfate, (Na2SO4), is usually the primary deposit instigating hot corrosion, and becomes more severe as the gas turbine section temperature levels increase.
