1.1 Pump (am-3227) Really an improvement?

Andy or Billfred have you tested the "THERMAL OVERLOAD PROTECTOR" that is described on the label? Is this something that might effect teams during matches?

Hey Allen,

We actually have run a prototype of this compressor on a full-weight robot chassis for just over an hour with two battery changes. This chassis was equipped with a pneumatic system with two 35 CI Clippard tanks to run new prototype shifting transmissions, with a high frequency of shifting cycles. The compressor's thermal protection system never kicked in.

Just for a bit of clarity, the thermal fuse protects the motor from over temp. Nothing to do with the air end getting hot. The air end heat has more to do with the physics of compressing air than compressor design. As others have mentioned using a KOP fan to blow air over the compressor head does wonders for this

Thank You Nick I assumed it would be fine, just hadn't seen a warning label that big on a compressor before.

The compressor is with UPS should be to AndyMark on Friday or Monday.

For those interested, CAD is now up on the product page.

Do we have any new pump data?

Yes, sorry it has taken so long. Here are results for a comparison between the AndyMark 1.1 Pump, the 98C Viair Pump, the Thomas 21ADC38/12-597, and the Thomas 405ADC38/12 pumps. I used approximately the same test as I did before in order to get these numbers.

Andy and the team at AndyMark, thanks for taking the time to do this testing we really appreciate it.

[AllenGregoryIV]

Thank you Andy and Team, looks like the new Viair specs are closer to the truth so the 98C probably should no longer be legal. That's going to be fun since so many of them are labeled "1.10 CFM" on the compressor.

Did you happen to record current for the compressors while doing these tests like you did for the other ones?
