Re: [PSUBS-MAILIST] pneumatic vacuum switch

Jay/Jon,
On the PDF for this product it does say  there is an O2 cleaned option.
However I'll be looking for something in a differant material.
If everything fails you have a valve to manually let in O2. Although it does
state that this is perfect for applications that require intrinsic safety.
A lot less bulky than a bellows & demand regulator.

The great beauty of Phil's bellows solution is that it requires no power and very little maintenance.  When the world is going to crap in your PSUB, the will still work even with a loss of power.

 

In the tech sheet for the electronic valve, it notes that nylon is used for construction and this is incompatible with 100% O2.

Alan,

 

Interesting units.  You'll need to confirm that they are compatible with O2.  I note in the text that they only mention specify compressed air.
