Continuous Blending on Compair 5405

[johnkendall]

Hi All,

Does anyone use a Compair 5405 for continuous blending? Any hints or tips? Also, does anyone know of a sensible source for a solenoid or similar to cut the O2 supply in the event of the compressor stopping.

Thanks

John

You can use a solenoid something like this to shut off the oxygen flow from the regulator.

Obviously check/clean for oxygen service, even though it's on the low pressure side.

Tie it in line to one leg of the 220 circuit powering up the compressor motor and the oxygen won't flow unless the compressor is on.

As far as continuous blending, there shouldn't be anything special there, other than verifying/changing the oil to synthetic and keeping the oxygen content reasonable (~36%).

Best advice I can offer is purchase the Oxyhacker book.

So what search should I do on ebay for the solenoid (I'm in the UK so need a 230v control, unless you guys reckon low voltage is the way forward).

Dunno, unless you can e-mail the seller to see if they have a european coil available. Either that or some sort of voltage inverter.

He does have other solenoids that use european voltage, so ask first.
