Multi-stage filtration concepts
Performance-optimized for your individual requirements
Multi-stage filtration systems ensure effective filtration and increased protection of turbines and compressors. Fouling damage 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, an upstream pocket filter protects the cassette filter of the final stage. 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.

Achieve maximum filtration performance with a simplified plant upgrade using the modular clip-on system.
Ideal for highest purity at EPA level:
3 stages with pocket filters, MVPGT and
spiderMaxx 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
Why is "Monte Bianco" the peak performer in power generation?
How does filtration come into play?
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
Ambient conditions vary by plant. From deserts, urban areas, or coastal districts; Sandstorms, humidity, or salty air. These conditions cause corrosion damage to equipment if not properly suited with the correct filtration system. Standardized filtration solutions sometimes do not take into account all variables, and therefore are 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.

spiderMaxx stands for a generation of casette filters that sets standards in terms of stability and torsional rigidity thanks to the innovative filter frame design. Even under high load, the casette filters provide peak performance for efficient energy generation and minimal downtime in power plants.
The high mechanical strength of the material offers dimensional stability throughout operational lifetime, even when handling large air volumes.
The T 60 sets the standard for pocket filter performance and high dust capacity. It's engineered to reliably stop aggressive, abrasive particles in demanding applications and extreme climatic conditions
The T 90's, with extended surface area and tear resistant pockets, is engineered for high dust holding capacity, long service life, and the arrest of aggressive and abrasive particles under virtually all environmental conditions.
Viledon MV extended surface V-style filters are specifically designed for systems that have stringent requirements for clean air quality.
Offering high operational reliability and cost-efficiency they are ideally suited for intake air prefiltration at coastal, offshore, and other high humidity locations. Here they provide optimum protection of the subsequent filter stages keeping them dry thereby extending the operational lifetime.
A new generation of powerful, efficient, economic and resilient cassette filters. With it's deeper filter depth, this series offer high operational reliability and cost optimization, while increasing the efficiency of turbine performance.
Viledon MVPGT-21 cassette filters offer an extended filtration surface for an increased lifetime cycle. They are particularly well suited for intake air filtration of gas turbines and compressors, especially for onshore locations.
