Technomadia Update: Catastrophic air filter Failure - Cause or Effect?

[eagle19952]

so...after further research:
Baldwin PA2721 crosses to the following spec Donaldson ECO style
1000 cfm @ 5" H20 P537447 ECOLITE

the following (DONALDSON ECO)  elements are suitable for CFM
BUT one must consider and understand inches of water column to properly select. Using the parameters previously discussed....
and then considering dimensions of available space, limits, obstruction piping calcs,  etc. etc. etc.

so as is shown the smallest least likely acceptable unit was sourced...

Baldwin PA2721 crosses to P537447 ECOLITE
1000 cfm @ 5" H20 P537447 ECOLITE
1000 cfm @ 6" H20 P527586 ECO-CM
1000 cfm @ 7" H20 P524837 ECO-II
1100 cfm @ 6" H20 P537450 ECO-CM
1200 cfm @ 5" H20 P537448 ECOLITE
1200 cfm @ 6" H20 P154927 ECO-II
1230 cfm @ 8" H20 P607373 ECO-SE
1400 cfm @ 7" H20 P524838 ECO-II
1500 cfm @ 5" H20 P537449 ECOLITE
1500 cfm @ 7" H20 P528722 ECO-II
1530 cfm @ 8" H20 P537456 ECO-SM
1550 cfm @ 8" H20 P537455 ECO-SM

a filter that can be candled would be MY least acceptable selection.
and for that reason alone I would be hesitant to use an ECO style.
someone who has 100's or 1000's of hours piloting a diesel engine and has a natural feel for engine response  might get by with that style filter....I just would not be confident using them.
more ramble to consider/follow....

pS...I now believe (after research) that the flow direction of the PA2721 Baldwin ECO clone was correct as installed....
