Hosco Mini-Filters and Station Filters incorporate SST wire mesh filter elements to provide absolute filtration at the specified wire mesh or micron size. There are 7 mesh or micron sizes available in the Mini-Filter products and 2 sizes available in the Station filter. The finest mesh size is 500 mesh or 25 micron and the coarsest mesh size is 40 mesh or 350 micron. In general, solvents and clear fluids would use the finer mesh and the solid color paints, metallic paints or highly filled or high solids paints will use the coarser mesh elements. The Mini-Filters have a small filtration surface area due to the compact design, and should only be recommended as a temporary filter to eliminate “dirt in paint” of a piping system when there are difficulties applying the coating without surface defects being created are a temporary condition. The Station Filter is a good solution to providing filtration in a Pressure Pot or 5 gallon pail pumping set up and some unique “in-line” filtration in larger fluid piping systems.
