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
