The Greyline Pre-separator connects to any dust extractor to add an additional stage of filtration during grinding and polishing operations.
- A bypass valve redirects dust flow into the connected dust extractor so crews don't have to stop grinding when the dust bag becomes full
- With the use of the bypass valve, the user can achieve up to nine bags of dust on the pre-separator to every one bag of dust with the dust extractor
- Utilizes Longopac bags
- Collapses for easy transportation
