Mann & Hummel water repellent turbine intake pre filter
Macrogen GT Duo has been specifically designed to meet the exact needs of gas turbine operators. With a low initial pressure drop and high dust holding capacity, combined with an inherent water repellency (coalescing and drainage), Macrogen GT Duo meets all the needs of gas turbine power plants.

More efficient filters are justified says Carlos Conti of Vokes
Moving from two to three stages has significantly increased system pressure drop but simultaneously reduced the quantity of dust reaching the turbine by approximately 98%, lowering the chance of engine damage – fouling, corrosion and erosion. To quantify this additional pressure drop, it is agreed within the power generation industry that an increase in pressure drop of 50 Pa causes a fall in efficiency of 0.1%. Quantifying the benefit is a balance between reduced fouling and increased pressure drop. The increased pressure drop can be estimated to restrict performance by approximately 0.4%, while cutting fouling provides a 1.2% improvement in output (empirical average). Therefore…

Hydrophobic media provides water removal and prefiltration
Vokes Macrogen GT Duo employs a hydrophobic media that provides effective water removal while in a study of 2 x 250 gas turbines in 2012 also delivered particle filtration to G4 or M5 efficiencies. This means that separate coalescer and prefiltration stages are unnecessary and that the redundant filter phase can be removed. The F9 final filters downstream from the Macrogen GT Duo system ran for a greater number ofhours and had a slightly lower pressure drop (105 against 110 Pascal) over the trial period. This result is due to the fact that the Macrogen has not only reduced the pressure drop but, at the same time, has increased the efficiency of prefiltration (from G4 to M5) better protecting the final filter.

New more efficient synthetic media for gas turbine inlet filters
Air filtration specialist Mann+Hummel launched compact filters Aircube Pro Power S and Nanoclass Cube Pro Power S for gas turbine air filtration that the company said are designed to deal with fine dust particle size for the first and ultra-fine dust for the second. Frank Spehl, Director of R&D at Mann+Hummel Vokes Air GmbH, Germany, explained that the new filter media is the answer to the challenges that operators of gas turbine plants face when they have to ensure that clean air is supplied to the engine. Whether gas turbines are operating in onshore or offshore locations, some challenges are common and include the fouling of the compressor blades, filter service life, system pressure drop, filter failure, and the corrosion by water and salt.
