1.1 Pump (am-3227) Really an improvement?

[Billfred]

I've had both in my hands--the difference in size isn't that significant (especially compared to the 100%-duty-cycle Viair pump 4901 used in 2015...), though obviously a pound is a pound.

We just got the 1.1 pump page up today, and it's entirely possible that we had a typo because that is a head-scratcher. I've got emails in to investigate the concerns you bring up (which are absolutely fair ones!).

Looking again I noticed the metric stats for the 1.1 Pump are copy-paste identical to the Viair 00090 specifications page.

I appreciate you following up via email to look into this. Hopefully all will be cleared up once the page is reviewed for accuracy.

I agree that the size difference is probably marginal - both are smaller (and lighter) than the Thomas compressors used in 2010 and earlier.

What would be very helpful is if AndyMark tests the fill time for both and posts that information for a given volume.

I'm partial to the 100% duty cycle compressors myself, those light-duty compressors heat up way too much.

BTW, this is a good place to compare and find different compressor options (as well as other parts):

How about a resource from two of the vendors we all use most?

motors.vex.com ..... The motor specifics that we use to design mechanisms.

and

pneumatics.andymark.com ..... People have trouble with spelling.
air.andymark.com ..... Sounds a bit too simple.
airmatics.andymark.com ..... Kinda catchy, but kinda strange.
(In short, I have not settled on a name.)

On this Andymark page, you can find specs and pricing on the most common FRC legal compressors out there. Teams can send in recommendations to Andymark about one that they use that is not featured on the site, and Andymark can add to the page or even sell it if they wish. There would be options to compare fill times for given sets of volumes across multiple compressors. Want more information? You can click on any compressor listed and see pricing, recommended vendors, and performance sheets. While we are at it, how about some nice looking performance graphs for visuals too.


Just an idea...
