Designed for use in moderate to high-pressure pipeline systems. Micro-sized pores and fiber dispersion give you optimum filtration at a fast flow rate. Pores also keep contaminants, such as sediments, from entering your bulk tank, but they are wide enough to ensure that butterfat flows through. Threadless design eliminates needle holes, resulting in greater purity and efficiency. Made from high-wet strength, randomly laid, single-ply polyester fabric.
