Supplier's note

  1. Key Technical Breakthroughs:

    • Corrosion-Resistant 316 Stainless Steel (Pro Model): Triple the chemical resistance of standard steel, enabling safe operation in acidic water.
    • Modular Tank System: Allows users to expand recovery capacity by 50% without replacing the entire unit.
    • 220V Global Compatibility: Reduces the need for voltage converters, streamlining deployment worldwide.

  2. Version Selection Guide:

    • Base Model (2.5''): Perfect for solo prospectors or shallow riverbeds where portability is critical.
    • Advanced Model (3''-4''): Ideal for small teams needing higher throughput without sacrificing mobility.
    • Pro Model (6''): Designed for commercial operations requiring large-scale recovery in corrosive or deep-water environments.

    With the Pro Model’s 316 stainless steel, you can operate in highly acidic mining sites while maintaining structural integrity. Pair its 200L tank capacity with the gravity separator to achieve 95% recovery efficiency—20% higher than industry benchmarks.
