Rust Preventive Diffusers

Self-contained, portable products that diffuse Zerust Vapor Corrosion Inhibitors (VCIs) chemicals to protect metals within enclosures.

Zerust VCI Diffuser Series

In addition to traditional VCI film and other packaging products, Zerust offers the 800 Diffuser Series. VCI Diffusers provide targeted corrosion protection in hard-to-reach enclosed spaces or can be used as added protection to Zerust VCI packaging products. VCI Diffusers emit powerful Zerust corrosion inhibiting molecules into an enclosure that settle on metal surfaces and protect them from corrosion. They are safe for electronics, odorless*, non-toxic*, residue-free, and are designed to work in restricted spaces.
