Clack Anthracite Filter Media 50 lb Bag - Superior Water Treatment, High-Performance Filtration, NSF/ANSI 60 Certified, Ideal for Multi-Media Filters

Clack Anthracite: High-Performance Filter Media for Superior Water Treatment

Clack Anthracite is a premium filter media, sourced from the finest Pennsylvania coal and specifically selected for water treatment applications. During production, it undergoes rigorous sizing inspections and laboratory quality control analysis to ensure it meets the highest standards for effective size, uniformity coefficient, specific gravity, acid solubility, and hardness. With its unique angular shape and density, Clack Anthracite provides longer filter runs, lower head loss, and enhanced performance in multi-media filtration systems.

Key Features: Superior Filtration and Efficiency

• Premium Quality Anthracite: Mined from top-grade Pennsylvania coal and subjected to strict quality controls.
• Longer Filter Runs: The angular shape allows sediment to penetrate deeper into the bed, extending filter life compared to equivalent filter sands.
• Reduced Backwash Rates: Requires less frequent backwashing, leading to operational efficiency.
• Multi-Media Compatibility: Due to its unique density (50 lbs/ft³), Clack Anthracite is ideal for use in multi-media filters, staying above heavier media like Filter Sand or Manganese Greensand.
• Certified to NSF/ANSI Standard 60: Ensures safety and quality for drinking water applications.
