We have two of the Balston 75-20 units... they work fine but
a ballast tank on the outlet is essential to even out pressure
spikes when the unit cycles between the two columns. We use
the Balston 72-012 "Receiver Tank".
If your house air is particularly icky an extra trap is a good idea.
Our house air is pretty oily.
Each Balston 75-20 will support more than one NMR system.
We have our 300 and 500 connected to one unit.
