With a production area of 60,000 m² across 8 plants, VOLZ produces over 2.5 million filters annually, offering more than 8,500 different products.
Quality and Production:
VOLZ Filters prioritizes quality control with in-house testing and modern management tools. They offer a wide range of filter classes from G2 to H14, ensuring high product quality. Their production facilities are among the most modern globally, with all stages from material manufacturing to final assembly conducted on-site.
Product Range and Services:
VOLZ provides a comprehensive product range for various applications, including air conditioning, painting, drying, and gas turbine technology. They offer services such as technical consulting, training, filter management, and on-site particle measurement. Their products are environmentally friendly, with synthetic media that are fully incinerable and certified skin-friendly.
Turbomachinery Filtration:
Effective filtration is crucial for gas turbines to prevent erosion, fouling, and corrosion. VOLZ Filters offers solutions tailored to different environments, such as arctic, desert, tropical, and industrial areas, addressing specific particle concentrations and sizes. The right filtration system enhances efficiency and reduces maintenance downtime.
Filtration System Components:
Typical components include weather hoods, anti-icing systems, protective screens, and multiple filter stages. In high dust areas, pulse-jet cartridges are used for self-cleaning, while static cartridges are preferred in low dust conditions for their low-pressure drop operation.
Goals and Efficiency:
The main goal of filtration is effective and efficient operation, with a focus on profitability. A 50 Pa loss in pressure drop can increase turbine output by 0.1%. VOLZ Filters provides solutions to optimize performance and reduce efficiency loss.
Services and Support:
VOLZ offers extensive support services, including location-specific measurements, microscopy, and filter evaluation. They collaborate with service companies for filter replacement, installation, and cleaning services.

Turbomachinery Gas turbine power plants are important in basic energy production, combined heat and electricity production and to level down consumption peaks. Compressors are used in pipeline transport, air separation units, pneumatic equipment and many more. The right combustion or compressor air filtration plays a very important role. Effective filters are used to prevent the most important and expensive parts of the power engine respectively compressor, to get dirt out and to avoid unnecessary erosion. Wrong filter systems will reduce the efficiency and performance of the turbomachinery and...

Filters for Gas Turbines-7

Principal components of a filtration system In practice there are typical components of a filtering system for gas turbines. Depending on local weather and/or dust conditions the air has to pass first a weather hood, an anti-icing-system and weather louvres. These stages will be followed by a protective screen to keep small animals like birds out. After these barriers up to 3 filter stages will follow, depending on the desired filter lifetimes due to maintenance intervals. Finally a transition piece together with by-pass flaps will follow the filter. In areas with high dust concentrations and...

Filters for Gas Turbines: VOLZ Filters| Goals of filtration There are different approaches to achieve the best filtration solution. The main goal is to reach effective and efficient filtration. Besides these, turbomachinery owners are interested in the profitable use of their filtration systems. It was determined that a 50 Pa loss in operating pressure drop at air intake system filters will increase the turbomachinery output by approximately 0.1%. The graph below indicates calculated efficiency loss over pressure drop difference for some gas turbines with different power output. This loss, calculated...
