Turbine Filters – The New Technology

Filtration for turbine engine is a critical aspect. If sub-micron particles, dissolved contaminants and liquids, water-borne salts or air are not trapped by the turbine filters, they can enter the turbines and result in fouling of compressor, blocked cooling routes, hot gas corrosion and blade erosion. Eventually these problems lead to lesser power output, high energy consumption and more frequent replacements or repairs of costly parts.

High Efficiency Particulate Air (HEPA) turbine filters are designed to keep the turbines running for the long run. The durable and advanced watertight turbine filter technology is used to maintain the clean engine performance, minimized downtime and lower maintenance and repair costs with the filter lifetime.

Most of the turbine filters are being given with a thin, 3-layer composite that captures the bigger contaminants, traps smaller ones and blocks the water droplets through their hydrophobic membrane that enables just pure air to pass through. In this way, most of the contaminants and particles are scanned and stopped to enter the turbine engine.

By stopping the ingestion of dry as well as soluble contaminants, the HEPA technology reduces the chances of compressor fouling for a long period of time. The HEPA turbine filters are developed to deliver the optimal ROI in challenging or tough applications across the industries. A great difference has been noted between the outcomes delivered by ordinary filtration systems and HEPA turbine filters.

The new upgraded turbine filters having hydrophobic HEPA technology has given huge value to the rotating equipment users. These turbine filters are engineered to ensure a basic retrofit replacement in the current filters, while in most of the cases, without any filter house modifications. These filter deliver benefits to equipment operators running immediate and base load engines who face losses in in terms of power output and compressor efficiency because of fouling. It also helps them to prevent corrosion that results because of salt ingestion.
