OMEGA / ALPHA 90 ... etc HP Check Valve Fix & Misc upgrades
« on: January 13, 2016, 11:57:47 AM »
Having received my Omega 90 as a Christmas gift from my son ... did not take long  :P and we already suffered a failure of HP side check valve.
Was noticing the on unit pressure gauge pulsing up, then dropping each pump cycle of unit.  After a bit of this the Circuit breaker on unit kept tripping.  Thanks to having a Shoebox for a couple years had dealt with HP pump issues and know right away we had a check valve issue happening.

After watching an AOA video online, had an overview of whats where and such basic knowledge of unit to dive in and chase the problem down.

Check valve in question easily accessed by removal of the HP safety disk ASSEMPLY.


What was found and supported by having NEW one in service parts bag was the Check valve being made from some plastic material of unknown quality ? * Being unit had less than 10 hours run time figured whatever valve was made of ... it Sucked !! so went about fabrication of a better design.

The BLACK valve is the offending stock part ... Cream colored the Custom made PEEK seal utilizing a 90 duro Poly o-ring as the actual sealing material.


New valve resting within cavity.  * Note radial clearance slots to allow HP air to pass along side valve.


After this modification it became immediately obvious the OEM valve was never upto the task and compressor was quieter, no pressure pulse/drop on gauge any longer with filling being faster too  8)

The ALPHA 90 Compressor  :)

So ... to add safety and some bling added some IMO what were useful gadgets to the ALPHA.

In the Coolant line a flow indicator ( Blue device with Red wheel ) so rather than just hear the pump running assuming it actually is creating flow ... if there is flow the red wheel spins wildly  ;)

Took out the fan and reversed flow to go towards coolant tank then added a stick on heat sink to side of tank to further dissipate heat.

Cut all the wiring ties loose and cleaned up there routing and bundling.
Drilled the Dead Head plug and hung it from handle giving a place to store Foster connector & hose coiled up out of the dirt and shop debris.
Small sponge chunk under Bleed off knob preventing the face full of water discharged when opening it.

Next was a long stem Stainless thermometer threaded into cap of Coolant tank.  Now we have a way to see what coolant temp is at a glance, make note of how hot unit runs during extended fill runs.

Last ( Shown in Complete unit Pic above ... 48" micro bore fill hose replacing the short @ 20" factory one.  Getting hose to tank on the floor now a lot easier.

Motorhead,
I assume that my Omega has the same check valve as yours, are you planning on making any more of them let me know and I will buy it from you.  My pump is exactly like yours except I bought too soon and got the high priced one.

Indeed the Pump mechanics are the same ..... best I know  ::)
Have no intent of manufacturing these as replacements, thread was just to share a possible "What To Do" is your Raptor/Omega/Alpha should have such an issue during its lifetime of use.

Surely Scott you could make one for a fellow marauder and GTA brother and the you could sleep in peace.   :'(   I would be forever in your favor.  What could I do to convince you to do this.

The shame of it all is, you had to do this to make the pump useable. Maybe you should bill back the manufacturer for your redesign!

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.
