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, 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 a three-stage system, an additional downstream cassette filter stage is added. This can provide filtration levels by 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.  This is how we provide customized solutions for you.

Discover our selection of tried and tested multi-stage filter systems for your custom-tailored solution

Ideal for highest purity at EPA level: 3 stages with pocket filters, MaxiPleat- and eMaxx cassette filters
Ideal for restricted spaces: the MaxiPleat modular filter system as a 2-in-1 solution
Ideal for preventing water ingress: hydroMaxx pocket filter firmly plugged on eMaxx cassette filter
Ideal for cleanable systems with safety filter stage: pulse-jet filter cartridges (conical/cylindrical) with MaxiPleat cassette filter

Power output is influenced by the performance of installed intake air filters and by the dust particle concentration at a gas turbine’s location.

How Efficient is Your Filtration System?

e.FFECT – Digital Algorithm for Optimal Filtration

Deserts, urban areas, or coastal districts. Sandstorms, humidity, or salty air.  The ambient conditions for plant and filter systems vary by location and can cause corrosion damage to equipment if not properly suited with the correct filtration system. Standardized filtration solutions sometimes cannot realize its full potential, as they are sometimes not designed to cope with specific requirements.

e.FFECT is the solution.  A proprietary software tool that optimizes filter systems and tailors them to specific environmental conditions.

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.
