FilPro Gravel and NJ Series Sand

FilPro Filter Gravel is a hard, whole-grain crystalline silica. Both FilPro Gravel and NJ Series Sand are durable and dense, making them resistant to degradation during handling, backwashing and extended use.

All FilPro grades are washed and screened under rigid SPS and quality assurance controls. The result is chemical purity and consistent size distribution designed to meet AWWA B-100 and ANSI/NSF 61 standards.

FilPro Filter Gravel is suitable for use in both pressure- and gravity-type filters, and are employed in municipal potable and wastewater filtration and various industrial processes, and make-up water applications.
