We had used the attached for comparisons earlier. (405 is the old Thomas KOP compressor, 415 was a similar model.)

Some comments:

1) The notable difference between the Viair 250C-IG and the Thomas 215 is duty cycle - 10% for the Thomas, 100% for the Viair. The weight is unfortunate, but it's a nice compressor.

2) In using the 90C, we used one of the KOP muffin fans blowing down over the cylinder - it helped a lot.

3) The 330C-IG on the chart is the bigger brother of the 250C-IG, but isn't within the FIRST limit.

4) When we asked the question, we were hoping that we would be allowed to use the braided hose (yes, it weighs more, but it's the piping right after the compressor that gets the most thermal abuse). Required was a surprise, but the net result was the same.
