Vapor Pipe Shield™, Your Most Powerful Shield Against Corrosion
Vapor Pipe Shield® is a patented, fully mechanical UL-listed solution that prevents corrosion in dry-pipe and pre-action fire sprinkler systems using proven VpCI® technology.
How it works
Installed in-line between the air compressor and dry pipe valve, it uses airflow to distribute VpCI® molecules throughout the system, forming a one-molecule-thick protective barrier on internal pipe surfaces to guard against corrosion.
