    AI Overview
    An 85-liter (or approximately 85 cubic foot) steel
    CO2cap C cap O sub 2
    𝐶𝑂2
     tank is a high-capacity, heavy-duty container frequently used for industrial, beverage, or diving applications. These tanks are known for their durability and high-pressure capacity. 
    Key Specifications & Features (Typical 85L/85cf Steel Tank) 
    • Capacity: 85 cubic feet (
      CO2cap C cap O sub 2
      𝐶𝑂2
       capacity) or 13 liters water capacity.
    • Material: High-strength Chromium Molybdenum steel, often featuring zinc-sprayed layers and epoxy paint for corrosion resistance.
    • Service Pressure: Roughly 2640–3442 PSI (high-pressure, low-pressure variants exist depending on the exact standard).
    • Dimensions: Approximately 26 inches in length and 7 inches in diameter.
    • Weight: Approximately 31–32 lbs empty.
    • Standard: Usually DOT (Department of Transportation) or TC (Transport Canada) approved for safety.
    • Valve: Commonly equipped with a CGA 320 valve, sometimes with convertible DIN/Yoke options for diving. 
    Common Applications 
    • Beverage Dispensing: Ideal for high-volume beer or soda dispensing in restaurants or large home setups.
    • Industrial: Welding and other industrial processes requiring consistent high-pressure
      CO2cap C cap O sub 2
      𝐶𝑂2
      .
    • Diving/Aquatic: Often used as "LP85" (Low-Pressure 85) steel scuba tanks. 
    Advantages of Steel over Aluminum 
    • Durability: Steel holds up better under heavy industrial use.
    • Safety: Steel is less prone to fatigue and failure from constant refilling compared to aluminum, although it is heavier. 
    Considerations 
    • Weight: Steel tanks are significantly heavier than aluminum counterparts.
    • Refurbishment: Many are available in "reconditioned" or "recertified" form, which means they are inspected, tested, and repainted to meet safety standards, often for a lower cost.
    • Maintenance: Need to be kept dry to prevent exterior rust, although many are coated for protection.

    What is the difference between aluminum and steel CO2 tanks?
    An Aluminium cylinder is 40% lighter than a steel cylinder. As compared to steel cylinders, Aluminium cylinders fail less often due to internal and external corrosion. Moreover, internal corrosion will deplete the oxygen content of the air which is a fatal deficiency.
