Compressor doesn't just work 2.5 minutes on the field. I don't know any team that would let their bot to go on the field with empty stomach .. uh .... I mean empty air tanks. Then it has to work during match. Times between matches are sometimes less than 20-30 minutes. Some of the times is used to adjust bot system and running tests, meaning more compressor usage. No wonder that number of teams have compressor overheating issues.
You cannot call it 100% duty cycle. Besides being incorrect, it is very misleading.
Comparing apples to apples, Viair 90C is 9% Duty cycle, just 1% less than Thomas 215. Which means that difference is marginal.
Having even small fan cooling off compressor will make more impact than switching from Viair 90C to Thomas 215. Especially considering that Thomas 215 is 3 times more expensive that Viair 90C. If you can spare 4 pounds on you robot Viair 250C-IG is much better choice for less money.
When more STEM teams exist outside schools than in them, that will be one indication that a true cultural change has occurred. - gblake [more]
