Preventing Corrosion on Airtac 4V210-08 Aluminum Bodies

Fighting Rust: Protecting the 4V210-08 in Humid Factories

The Airtac 4V210-08 features a high-grade aluminum body, but in coastal or high-humidity plants, oxidation can still occur.

1. The White Powder Effect

Oxidation appears as a white powder on the surface. If this enters the ports, it can tear the seals.

2. Protection Tips

• Hard Anodizing: For extreme salt-spray environments, inquire about our specially treated 4V series.
• Shielding: Use a plastic or stainless steel valve box to prevent direct contact with moisture.
• Wipe Down: During monthly maintenance, a light wipe with silicone oil will keep the body looking and performing like new.
