Design
The MOGS-100 oxygen generating system manifold serves two purposes:
To connect the MOGS-100 to each bottle for filling
To connect the bottles to one another for equalizing during trans-filling
(filling smaller bottles from larger ones)
A shut off valve is located at the end of the manifold, downstream of the K-type storage
cylinders. This valve stops the flow of oxygen when a small cylinder is not attached in
the filling station and also allows the user to fill the storage cylinders. Every oxygen
cylinder is equipped with its own shutoff valve, so any additional valves in the system are
unnecessary. It is recommended that the filling manifold be as simple as possible with
few valves and fittings in order to keep the number of potential leak points to a minimum.
Preferred materials for use in high pressure oxygen generation include, but are not limited to:
Stainless Steel
Brass
Bronze
Installation
When building and installing a cylinder filling manifold, it is necessary to ensure that the
threads on all NPT connections and all stainless steel on stainless steel connections are
lubricated by Teflon tape or a similar pipe dope (such as Krytox grease). It is equally
important to ensure that the threads on all compression fittings, such as the
CGA-540
connections on K-type cylinders, are clean unless the threads are stainless steel on
stainless steel. All fittings should be tightened with a wrench (much tighter than hand
tight). Once the manifold is built and installed, it needs to be checked for leaks with
oxygen at
2200 psi (152 bar)
. This can be done by shutting the valves on all bottles and
using the MOGS-100 to fill the manifold to 2200 psi (152 bar) . Each joint should then
be checked for leaks by applying soapy water to the joint using a spray bottle or a small
paintbrush. If bubbles are formed, it means that there is a leak. If a leak is found, the
joint should be tightened further with a wrench. If this does not work, the joint should be
disassembled and cleaned, then reassembled and tested. If this does not work, the leaking
fittings need to be replaced.
