    Packaging, Logistics and VCI Anti-Rust Protection

    Because oil-free elements are highly precise components with zero oil films inside the compression chamber, they are vulnerable to atmospheric moisture during international transit. Each genuine 1616 5904 81 air end is tightly wrapped in professional VCI (Volatile Corrosion Inhibitor) protective materials before being sealed inside a heavy-duty industrial export wooden crate. This special environment provides a certified 1-year anti-rust and anti-corrosion guarantee from the factory, ensuring the component arrives at your facility in pristine, factory-fresh condition.
