Take a look at "Protective Blast Cage" (under air tanks, compressors, etc.) SH-T HAPPENS!!!
Yup that is pretty ugly looks like the filter and or brass fittings failed catastrophically for sure.
The fear of this is the main reason I have as yet not installed check valves to keep my filters pressurized as some do. I just don't trust the China made high pressure stuff that much.
