Why do some of the droids look like they are air breathing?

Propely a lame question, but who cares im on the forums lol.
Why does HK, the IGs, Magnaguard and B2 look like they are air breathing? I just realized it by looking at R2s kit and along with K2SO and Chopper they are the only ones not doing it

Probably just different skins on a base template. Just a guess, but I've noticed it too and it's how I justify it to myself.

They are moving about so their joints don't cease - oil baths are hard to come by and some battles are fought on Tattoine - sand gets everywhere! lol
