You might want to try wading through the Fram web site <http://www.fram.com/>. I tried a search on Warner Lewis and got a lot of hits but nothing I recognized right away (sorry--short attention span) as a manufacturer. Try it--your mileage may vary.

My experience is that getting design information may be a problem unless you're a big customer. Most manufacturers view all such things as proprietary including the pedestrian stuff that anyone could do if they felt like it. If the filter is meant to be a stationary installation with a significant volume, it may have had to demonstrate compliance with ASME code here in the states at some point. The fact that there's a published test pressure that's 1.5 times the working pressure is an indication that someone was thinking about the ASME Code when it was designed. If the filter were in full compliance, it would carry a code plate welded or perhaps stuck to the body of the filter. How do you know what the test pressure is? Is there some kind of document you could trace back?
