Multi-stage filtration concepts

Performance-optimized for your individual requirements

Multi-stage filtration systems ensure effective filtration and increased protection of turbines and compressors. Damage due to fouling is kept to a minimum. Unplanned downtimes can be avoided, the general maintenance costs are reduced and optimal turbine efficiency can be achieved.

In a two-stage system, the cassette filter of the final stage is protected by an upstream pocket filter. In three-stage systems, another downstream cassette filter stage is added. This can provide filtration levels up to EPA standard. The selection of filters for each stage depends primarily on the environmental conditions around the plant, as well as on any space limitations.

How efficient is your filtration system?

Find the optimal filter solution for your plant with e.FFECT based on ISO 16890

Standardized systems for intake air filtration are frequently inefficient and do not make full use of the optimization potential. The more specifically filter systems are customized to the respective ambient conditions and plant requirements, the greater performance and reliability they achieve.

Our experts work with you to develop the best filter solution for your plant on the basis of the testing standard ISO 16890. In the filter evaluation, typical urban and rural particle size distributions are considered based on the particulate matter fractions PM1, PM2.5 and PM10, and filter efficiency grades are determined accordingly.

With e.FFECT, the electronic Freudenberg Filter Efficiency Calculation Tool, calculating the optimal filter solution is extremely simple. The local ambient conditions and specific process requirements enter directly into the calculation. Multi-stage filter systems can then be objectively compared. This simplifies the selection of the best filter concept for your needs.
