Anyone have a flowmeter handy? Maybe just time the two compressors to fill a known volume would be enough.

This difference in the data sheets is critical - people should be sure to note that difference as the tables and spreadsheets that some have shared are significantly misleading without noting that. We use the 215 Thomas compressor because it edges out the Viair compressor when using comparable nominal voltage ratings, and is built to what we feel is a higher quality standard by a more widely known and reputable company.
