Type 31-LSF

The two-stage Eaton Type 31-LSF Separator/Filter removes 99% of all particles larger than 0.3 microns and is for applications requiring extremely fine entrainment removal.
The first stage is a centrifugal separator that removes slugs and heavy liquid loads. The second stage uses filter elements to remove nearly all remaining droplets plus particles as small as 0.3 microns from air, gas and steam processes. The most common application for the LSF Series Filter/Separator is for natural gas, but it is also suitable for those requiring highly pure output.
