Clack Filter-Ag Plus – Advanced Suspended Solids Filtration

Clack Filter-Ag Plus is a high-performance filtration media made from clinoptilolite, a natural ore with superior advantages over traditional sand and multimedia filters. Its angular granules and microporous structure enable deep bed filtration, reducing suspended solids down to 5 microns or less while maintaining high flow rates and low pressure loss.

Key Benefits:

• Superior Filtration Efficiency – Removes dirt, silt, and organic matter with granules as small as 3 microns
• Extended Filter Runs – Deep bed filtration prevents clogging, reducing backwash frequency and water waste
• High Flow Rates & Cost Savings – Supports higher service flow rates, lowering equipment and operational costs
• Lightweight & Eco-Friendly – 50 lbs/cu.ft. bulk density reduces shipping costs and handling effort
• Versatile Application – Works in pressure or gravity systems and can replace multimedia filters
