Roots DVJ Whispair Dry Vacuum Exhausters
Dry vacuum exhausters with Whispair porting.
Overview
The DVJ pulls hard vacuum without seal water. Whispair porting keeps the discharge quiet even at deep vacuum, and dry operation is the right answer where seal water contamination or freezing is a concern.
Key features
- Dry — no seal water piping or blowdown
- Whispair porting for quiet deep-vacuum service
- Preferred where seal water is unavailable or freezes
