Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Which one delivers more volume?

1.8 CFM @90psi or 1.7 CFM@100psi

1.8 cfm @ 90 psi delivers more volume.

cfm (cubic feet per minute) is the volume of the flow, regardless of the pressure. 1.8 cfm is a larger volume of flow than 1.7 cfm.

tks. I should have phrased that differently. I was wondering which compressor delivers more volume @ 100psi. The one which is rated 1.8 cfm @90psi or the one rated 1.7 @100psi. If it helps, one compressor delivers 2.6 cfm @ 40psi and 1.7 cfm @ 100psi, the other one delivers 2.7 cfm @ 40psi and 1.8 cfm @ 90psi. The first one loses the ability to deliver .9 cfm over the rise in pressure from 40 - 90 psi, the other one loses the ability to lose .9 cfm over the pressure change from 40 - 100 psi. So I'm wondering how much volume the one which has a rating for 90psi delivers at 100 psi.
