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.
Ambient conditions vary by plant: from deserts, urban areas to coastal districts influenced by 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 local requirements.
e.FFECT is the solution. A proprietary software 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. The performance of multi-stage filter systems can then be objectively compared. This simplifies the selection of the best filter concept for your needs. The added value for you: intake air filtration that is optimally aligned to performance and functional reliability, reducing downtime and lowering operating costs.

Fine filter certification
The independent institute EUROVENT Certification has developed an international certification program for fine filters that has recently been revised on the basis of ISO 16890. All Viledon fine filters are certified by EUROVENT.
Energy efficiency classes
EUROVENT, the European association of manufacturers in the HVAC industry, has developed a classification system for the energy efficiency of air filters. Freudenberg has contributed significantly to the development of this classification. Your advantages: Energy-efficient filters can be identified at a glance.
