The filters are constructed with the aim to reach the lowest possible initial pressure drop. The producer developed filtration materials which are unique for its kind. Initial pressure level of 0,07bar is accomplished! The lower the pressure drop means the lower operating cost of the compressor. In additional, the lifetime of the filter element is ensured as well.
Filters are produced in following mentioned sizes. They are built in according to the standard ISO 8573.1:2010. This standard declares the qualitative requirements for the level of dust particles, oil impurities and pressure dew point of the compressed air.
