1.Which supplier is the best source for Roots 45 URA1 DSL blower.
2.Have been offered a J type Roots blower Is a J better than a DSL?
roro
DSL refers to the lubrication (dual splash). There is oil in both ends . (no grease)
A J blower can also be DSL...maybe they all are not sure
The J is "whispair". They are quieter but can only be used in certain orientations.
You would have to consult a manual/expert as to the fitness for your application.
pdblowers.com is a good source for info
