Cut a pipe on the back of a fridge and it'll run open circuit just fine. Doesn't make it appreciably louder. (beware, some fridge gasses are illegal to vent to the atmosphere, and others are pretty explosive)

Try to run a plasma cutter, or a 1" impact wrench out of a fridge compressor...

Those things also don't need 400psi.

A modified fridge compressor could have 4x the capacity at 100psi and be suitable for a small workshop.

Do you understand the concept of air flow at a specific pressure ? 15CFM at 90psi is no small feat.

Lowering working pressure does not increase CFM, pump have a fixed displacement at their most efficient RPM, it's not gonna change...
