Overview
Oil removal before brazing
The VAB Oil-Removal Furnace is a vacuum system used to remove oil remaining on parts after forming or stamping. The process heats components to the oil-evaporation temperature under reduced pressure, allowing oil vapors to be extracted and condensed in a dedicated exhaust system. The recovered oil is collected in a storage tank. This ensures parts achieve the required cleanliness level before the brazing process, improving joint quality and consistency.
Applications
Where oil removal is used
Removal of oils after stamping or forming
HVAC&R, automotive, aerospace and industrial aluminum parts
Any aluminum brazing line requiring clean components
Features
How the oil is removed
- Vacuum oil-separating system
