Our VEL series brass bodied (polypropylene) inline filters are an ideal solution for most applications in small plants which require easy cleaning and maintenance. There is a simple hand operated valve to the base of the filter for rapid cleaning. When turned the particles trapped by the filter are expelled through the valve to waste, although a full clean is still required from time to time. A pressure gauge on the filter head indicates a pressure drop when cleaning is required. VEL filters are available in ⅜” ½”, ¾”, 1”, 1 ¼”, 1 ½” or 2” BSPP with 150 mesh cartridges.
