A candle filter is a membrane-based fluid filtration system engineered to remove fine particulate contaminants from industrial fluids such as spent oils, coolants, and machining lubricants. Unlike traditional disposable media, PRAB’s candle filters use high-performance membrane wafers to reliably capture solids at 1–3 microns, improving fluid quality and enabling recycle and reuse in precision metalworking applications.
PRAB Candle Filters are designed to deliver high-clarity fluid filtration, low maintenance, and industry-leading uptime for demanding manufacturing environments. These systems integrate advanced membrane media and automatic self-cleaning technology to keep your operations running efficiently with minimal operator intervention.
