Microfibre Filter Elements for Oil Mist Separators

Filtration efficiency of 99.99%

Home » Microfibre Filter Cartridges for Oil Mist Separators

MFK-032-39.4 and MFK-674-39.4 Microfibre filter elements for Oil Mist Separators

Filtration elements for oil mist

The microfibre filter elements developed by FRANKE-Filter are responsible for the precise filtration process. Due to their special nature, they guarantee a high filtration efficiency of 99.99% at 0.1 µm for oil mist. Further, the filter cartridges grant a smooth process with a maintenance-free operation time of up to 30,000 operating hours.

Highest efficiency and durability, clean air and a long lifetime

The filter cartridges used by FRANKE-Filter (MFK-032-39.4 and MFK-674-39.4) meet a high standard and have a service life of approximately 2-5 years. With a filtration efficiency of 99.99% and less than 5 mg/m³ residual oil particles after the filtration, our filter cartridges meet almost all environmental protection requirements. With an Oil Mist Separator from FRANKE-Filter you do not only protect your turbine or your employees but at the same time, you are also contributing to environmental protection.

The replacement of the filter elements

As soon as the microfibres of the filter elements of the Oil Mist Separator are almost completely saturated by impurities and lubricating oil particles, the filter cartridges need to be replaced. The vacuum pressure gauge of the filter system indicates when to replace the filter cartridges.

The replacement is conceivably easy. After a few minutes, your Oil Mist Separator is ready for use again and ensures a constant vacuum and the consistent quality of the lubricating oil.

Caution: Fake MFK filter cartridges!

Not all filter cartridges are equal. The filter cartridges used by FRANKE-Filter are optimally matched to the operation of our systems. For some months, however, there appear to be dealers on the market selling fake filter cartridges under our name and our item number. These filter cartridges are NOT comparable with FRANKE-Filter MFK filter cartridges and do not reach the required efficiency result.
