1.1 CFM Air Compressors?
 

What air compressor did your team use this year? Given the increase in the allowable air compressor CFM rating to 1.1, I am wondering what new legal compressors teams have found.

Re: 1.1 CFM Air Compressors?
 

We used a Thomas 215 this year. It run below the 1.1 CFM limit, but the rate at high pressures made it a great compressor to use this year. It does run hot, however. A fan on the piston housing cooled it nicely.

We also use the Thomas 215. It's worked nicely for us for three years.

Re: 1.1 CFM Air Compressors?
 

We used a viair 98C. However there website is now listing a higher CFM because they are using 13.8V instead of 12V this wasn't the case during build season. The ones we own list a 1.10 CFM at 12V directly on the compressor. I may need to call Viair and see if we can get 12V specs for their compressors published again.

Where are you purchasing the 215 compressor? The only place I've seen is here: http://cfpwarehouse.com/shopsite_sc/...oduct2931.html

But it looks super sketchy.

Do you contact Thomas directly?

Re: 1.1 CFM Air Compressors?
 

The VLAIR 330C-IG is rated to 1.06 CFM at 12V and is 100% duty cycle, so no more overheating if it runs constantly...
The downside of course is that it also weighs over 8lbs.

Would be handy if you needed a lot of air pressure and had spare weight to play with I guess. :rolleyes:

Re: 1.1 CFM Air Compressors?
 

Eyeroll completely inappropriate here. This is probably the perfect off-board compressor. You don't care about weight, and the fill-rate should be comparable to or better than the 98C or 100C. If you've got a ton of air to store, it's not going to mind running forever, either.

I'm not clear on why everyone is so big on the Thomas 215. Unless the viair 98C and 100C suffer significant performance hits for running at 12V instead of 13.8V, it seems like they have better flow rates and fill rates than the 215.

Anyone have experience with this compressor? Advice on where to buy?

We ran an off-board set up this year and loved it, I don't think we'll go back to on-board any time soon.

However, our old trusty Thomas compressors are getting old, and we are looking to upgrade. This looks like a great alternative.

I really enjoyed how your cart included the compressor and water bottles for the drive team. How many pneumatics did you actually have on your robot this year to be comfortable not running a compressor on the robot? How long would it take to fill up your robot air tanks?

I am a bit skeptical of running no compressor on one of our teams robots. Especially with our pneumatapult on our bot this year.

Also not that I have any experience with the compressor but, Amazon seemed to have some comparable prices for the 330C-IG.

I've attached our calcs for this year, using 1114's pneumatics calc sheet.

We had 8 tanks, all roughly the size of the black Clippard tank.

It took about 5 minutes to charge using an old Thomas compressor.

Could you post the link for that calculator? I've been looking for something like this.

Re: 1.1 CFM Air Compressors?
 

We got ours from http://www.ridetech.com/store/215-th...or-100psi.html

Re: 1.1 CFM Air Compressors?
 

Thanks. I was searching too narrowly I guess. I was searching for "215ADC38/12". I lose 5 Google-Fu points.

Re: 1.1 CFM Air Compressors?
 

I contacted Vair about their 1.1 CFM compressors, and the customer service rep I spoke with said that the specs they have listed online are incorrect. He was familiar with the FRC pneumatic rules, and confirmed that they are NOT in fact FRC legal.

I wonder how many teams ended up with illegal compressors because the spec sheet was wrong...

Re: 1.1 CFM Air Compressors?
 

Well considering that spec sheets can be used to prove the legality of components to RI's. What spec sheet evidence is there that these are illegal?

Obviously if it would create an unfair advantage, it would be un-GP to use even if the fact sheet was wrong.
