The ECONOX-UF is the entry-level ULTRAFILTRATION, completely manual, which allows you to treat a good amount of sap at a lower price. The series includes a 5 cartridge canister of 20” prefilters for prefiltration and all the necessary instrumentations. Available from 1 to 4 MEMBRANESs, and completely modular, the ECONOX-UF is a very good choice for smaller operations.
