Néha zavarbaejtően sokféle elnevezésük van, pedig legtöbbször ugyanarról beszélünk. A cél a levegőelőkészítés, ezek a legújabb generációs berendezések azonban már elektronikusan vezéreltek, sőt a gépjármű több részegységével párhuzamosan kommunikálnak is.
A levegőelőkészítő egységek élettartama nagyban növelhető a légszárítópatron időszakos ellenőrzésével, illetve szükség szerinti cseréjével. Ezzel időben elkerülhető, hogy a rendszerbe olaj, víz, esetleg egyéb szennyeződés kerüljön. A rendszeres ellenőrzéssel nemcsak az egység és az egyéb szelepek élettartama növekszik, hanem az üzembiztonság is. Az utólagos javítási költségek minimalizálásáról már nem is beszélve.
