Larry,
You mentioned higher pressure, do you have any idea if it has high airflow too.
It looks like it uses very small id diameter hose 1/2"?
While the direct-it-in systems use 1 1/4" id hose.
If some of the hose runs with the viking were over 10 feet I would think that would be a lot of resistance to overcome with 1/2" hose?
Thanks.
