I have been doing a little research into air flow regulators for the AT44 and I noticed some drilling a small hole into the tube. They explain that this is to prevent aerating. Can someone please tell me what this is and what happens when the vent is omitted?
Thank you.

The hole is to vent the spring section of the regulator to prevent any buildup of pressure between the two piston O-rings.... Without it, if either O-ring leaks even a little bit over time, the pressure will wander.... Basically it supplies a constant (atmospheric) pressure reference so that the regulator works properly....
