What is a vacuum degreasing parts washers?

Yes—vacuum degreasing parts washers are a more advanced and efficient form of parts cleaning, especially used in high-precision industries like aerospace, medical, and electronics manufacturing.

Here’s a quick rundown of how they work and why they’re valued:

What They Are

Vacuum degreasing systems use solvents (often modified alcohols or hydrocarbons) in a sealed chamber under vacuum conditions. The vacuum lowers the boiling point of the solvent, improving cleaning efficiency while minimizing solvent emissions.

Key Benefits

  • Extremely thorough cleaning – even on complex geometries, blind holes, or capillaries.

  • Low emissions – because it’s a closed-loop system, it meets or exceeds most environmental regulations.

  • Dry parts quickly – the vacuum helps evaporate residual solvent for fast, spot-free drying.

  • Solvent recovery – systems usually distill and reuse solvent, reducing cost and waste.

Common Use Cases

  • Cleaning parts with tight tolerances or delicate finishes

  • Pre-coating or pre-assembly cleaning

  • Final cleaning before vacuum brazing or plating

  • Removing machining oils or waxes from high-end components

Manufacturers like Ecoclean, Pero, and Dürr are leaders in this space.
