They claim 100 hours of service life. They are typically used in medical equipment (BP measurement). They are very simple and efficient for air output for their size.. I have a couple of different styles inbound to see if there are internal and quality differences.

Here are the videos today...

First is the first curve run test - Still a bit rich in the middle but I have to tweak the software to add a bit more base exponential.. My test today showed that I can mimic the muffler curve but that too would probably be a bit thick in the middle -


Second is a short video of the idle - I went into the shop to get something and it idled like this for 2 minutes. Shot some video and was pleased to see it took throttle (albeit loaded up a bit)


Third is a run where I adjusted to mimic the Muffler pressure curve - I didn't work the curve at all just raised the pressure and closed the HS needle 2 clicks to adjust for the higher pressure (0.9PSI vs 0.6). Was playing a bit to try and clean up the mid range...
