Auxiliary Air and Helium Supply
An industrial-duty oil-less piston
compressor generates 3.5 cfm of air at 40 psi, which provides the required flow
rate and pressure to operate the Model 5 Console with one or two outputs. The
compressor has a 3/4 hp, direct-drive motor with thermal overload protection.
The helium supply comes from a rechargeable
aluminum cylinder. A pressure regulator connected to the cylinder is used
to control and maintain the required operating pressure of 20 psi. This
combination can deliver 20 hours of operation with a single output or 10 hours
with two outputs. The regulator has a CGA 580 nipple fitting, so it can connect
to a bigger bottle of helium if desired. Also included is a transfill
manifold to recharge the aluminum cylinder with a fresh supply of helium gas.
