VEC check-valve filters are specially designed for 3/8″ flanged nozzles. Large filtering surface grants long exercise period without cleaning necessity. We recommend to assemble these filters on small capacity nozzles to avoid clogging and enhance their performance.
To figure out mesh sizes one has to count the number of openings from the centre of any one wire to the centre of a parallel wire one inch away. The number of openings in a filter cartridge is the mesh size. We highly recommend to add filters to small capacity nozzles to hold fine particulate matter. Please refer to the table below.
