Gardner,

The capacity of the pump, 3.15 cu Ft/min is still around 90 liters/min,
is not the most important characteristic of the pump, it just takes a
bit longer before pressure builds up inside the bag. With 90 lit/min you
can go a long way, even for bigger projects, more important looks to me
is the maximum of vacuum pressure you can create with the pump ...
