Craig, Does this client have a problem with air compressors? I guess if you don't want to maintain supervisory air on the system then you could eliminate the air compressor. But that would be a noncompliant way of doing the system.This would then be a non-interlocked system no better than a simple dry pipe system.But then again,a dry pipe system requires an air supply.So see my original question.
