FilPro Filtration Sand and Gravel

FilPro filtration sand is produced from hard ore quartz sand. Resistant to degradation during handling and backwashing, this durable sand effectively performs in a filter to reduce time and optimize flow.

The sub-angular grain shape of FilPro media will provide solid holding capacity and a transport mechanism of any filter design. FilPro grades are engineered to optimize the performance of air scour portable water filters and tertiary filtration systems, and have been proven effective in iron and manganese removal, industrial process water filtration and waste treatment systems.

All FilPro grades are processed and sized with strict adherence to quality assurance controls, and meet AWWA B-100 and ANSI standards for consistently uniform and chemically inert filter media. They are certified under NSF-61 by the National Sanitation Foundation.
