\n\t\t\t\t\t\t\t\t\tAnyone looking for a SEPAR filter will quickly come across two product lines: the SEPAR SWK and the\nSEPAR LKF. Both systems reliably protect diesel engines from fuel contamination\n\u2013 but they are based on different filtration principles and were developed for different\nrequirements. This article shows which system is the right choice, and when. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The SEPAR SWK is a high-performance fuel filter based on a proven 5-stage filtration principle that combines centrifugal separation with hydrophobic filtration. It is designed for use under demanding conditions \u2013 fluctuating fuel quality, vibrations, limited installation space \u2013 and is used in a wide range of applications. The SWK is particularly common in marine applications, as it meets the requirements of relevant classification societies. In addition, it is also suitable for off-highway vehicles, industrial applications, and on-highway applications, making it one of the most versatile filters in the SEPAR portfolio. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

    The SEPAR LKF operates on a two-stage hydrophobic and coalescing filtration principle that removes water and dirt particles from the fuel flow with a water separation rate of over 95% \u2013 both free and emulsified water. The LKF series covers a broad range of applications: from tractors and construction machinery to trucks, buses and commercial vehicles, right through to stationary industrial systems. With the LKF-Automotive (up to 3 l\/min), the LKF-Industrial (up to 8 l\/min) and the LKF-Automotive HD (up to 15 bar for common-rail systems), the right version is available for every application.
