Turbomachinery equipment are critical pieces of equipment that ingest large quantities of air. A gas turbine intake, for example, ingests up to 98% air and 2% fuel. Air quality is critical for the performance and life of the equipment and directly impacts an operator’s availability, reliability and profitability. Whether you operate a gas turbine, wind turbine, large industrial air compressor, or other turbomachinery, high quality air filtration will quickly bring important benefits to your bottom line.
Environmental and operational conditions can vary drastically with each site, therefore, the required filter solution should not only be efficient but also adapted to your local site conditions and challenges.
The following Insight articles cover a wide variety of topics that will help you improve your overall operations.

Meeting stricter marine emissions standards while continuing to run reciprocating engines will significantly increase operating costs for commercial shipping operators. To support low emissions, liquified natural gas is becoming a key marine fuel due to increasing availability and clean combustion.
Gas turbines are susceptible to fouling and damage if water droplets and water soluble contaminants, i.e. salts, are ingested by an engine.
During heavy storms, filters are subject to a lot of water. Both filter efficiency and pressure drop can be impacted if the filter drainage is not properly designed or the media hydrophobicity is not sufficient.
Hot corrosion is a source of nonrecoverable degradation on gas turbines. It is a chemical reaction between salts, sulfur and heat, where the damages can reduce an engine’s life by up to 75%. One of the most effective methods is to eliminate the contaminants triggering the chemical reaction. This paper examines the causes of hot corrosion and assesses various methods of mitigation.
CamGT filters have been engineered to excel in extreme environments. They virtually eliminate fouling, corrosion and maintenance downtime, all at a lower and more stable pressure drop.

Frequent pressure and short filter replacement intervals led to high operational costs. Camfil's Cam-Flo air intake pre-filters and CamGT EPA air filters met their goal of 8000 hours of life and reduced pressure drop by 50%.
Plant located in the Gulf Coast of Louisiana upgrades to the Cam-Flo pocket air filters and CamGT 4V-300 EPA E10 filters after tests show lower pressure drop, lower engine degradation, and signifcant savings as a result of filtration.
The test showed that that the CamPulse GTC gas turbine cartrdige filter upgrade would improve pressure drop and increase power output despite the salt laden, high humidity environmental conditions.
With a growing demand for greener practices, and rising operational costs, it has become imperative that gas turbine operators cut their carbon footprints. Upgraded air intake systems are one of the easiest, most cost-effective ways to meet these demands, while improving operations at the same time.
