air compressors; advantage of twin tanks...?

[Bernard Arnest]

Hi,

Broadly there seem to be two types of larger portable compressor: 7-9gallon twin tank wheelbarrow compressors, which sell for about $650 new, and then 15-30 gallon single-tank compressors, which with the same quality of motor and compressor head cost about the same.

So, what's the advantage of two parallel tiny tanks, versus one larger one? Ultimately it doesn't seem much lighter.

just curious!

To make them easier to roll, carry, transport, or store, and to make them more stable as they stand.

One might just as well ask, why does the human body have so many organs in pairs?
