While there are many types of filters that can be used in a gas turbine, most can be divided into two categories—barrier filters and pulse filters. BARRIER FILTERSA simple example of a barrier filter can be found in your home. All heating and cooling systems in homes and apartments require air filters to function properly. […]

MERV—Minimum Efficiency Reporting Value vs. Percent Efficiency
In the United States, ASHRAE standard 52.2: 2007 gives us the requirements for filter efficiency. Efficiency is determined by types of particles, rather than an overall efficiency. This rating is known as MERV—Minimum Efficiency Reporting Value and is in contrast to percent efficiency. MERV rates both how effective the filter is at stopping particles of […]
Stages of Filtration for Gas Turbines
For a gas turbine, rarely is a single filter sufficient to reduce or eliminate particulates. Therefore, multiple stages of filtration are required. A filtration “stage” is simply a type of filter that is designed to remove either a specific contaminant or type of contaminant from the air or is designed to filter a specific particle […]
Hazardous Locations and Environments for Gas Turbines
Because gas turbines have to operate in a wide variety of environments, they are often subject to many different hazardous mediums that have the potential to cause fires and/or explosions if exposed to the electrical components of a gas turbine filtration system or the gas turbine itself. Electrical components require a wide variety of housing […]
Gas Turbine Filtration
Gas turbines are powerful machines that require a tremendous amount of air. To give you an example of how much air is required by the average turbine, a 30,000 hp turbine might have a mass flow of over 500,000 lb/hour. If the air that’s being pulled in has 1 part per million (PPM) of particulate […]
