Supplier's note

  1. Three Breakthroughs:

    • Material Reinforcement: The Pro Model’s 30% thicker steel walls exceed industry standards, enabling safe handling of extreme pressures (e.g., in heavy-duty compressors).
    • Sealing Technology: Enhanced gasket design in the Advanced Model reduces leakage by 25%, ensuring consistent airflow in pumps.
    • Modular Passages: Customizable hole configurations allow users to optimize fluid dynamics for specific applications.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard workshop compressors or low-pressure systems requiring basic durability.
    • Advanced Model: Perfect for industrial pumps or engines needing prolonged service life (e.g., 24/7 operations).
    • Pro Model: Designed for heavy machinery and high-pressure environments (e.g., mining or oil rigs), where tripled durability and faster flow are critical.

With the Pro Model’s 130 PSI capacity, you can safely power high-stress systems. Pair its reinforced steel with optimized flow paths to reduce downtime and energy waste.
