Hello Phil

A player suction unit is high vacuum, say 60 inches of water at maybe
40 cubic feet per minute.  The lee unit is low vacuum and higher volume.
On the player suction unit looks like the speed was reduced to lower
vacuum and at the same time the volume was also reduced so not
enough volume to do the job.
