• Whenever possible, switchoff theair supply
duringmachinestandstills, at theendof shifts,

• Whenhigher pressure levelsare requiredat spe-
cificpointswithin thenetwork, usepressure
boosters insteadof increasingpressure through-
out theentiresystem.
• Carefully check theneed for filters, becauseevery
filter stage reduces theflow rateand increases
thepressuredrop. Follow themotto: “asmuchas
necessary, as littleaspossible”.
• Timely replacement of filter elements inservice

• Useamultipledistributor insteadof aseriesof

tor.

Compressedair preparationandenergymonitoring– tips
• Decentralised compressedair preparationdirectly
at thesystem reduces the riskof components
being contaminated.Moisture, contamination
andoil haveanegativeeffect onsealsandwash
the initial lubricationout of the components.
• Tubingmaterialwhich issuited to theenviron-
ment prevents chemical, physical andmicrobial
damage.
• Useonlysuitable toolswhen cutting tubing to
length.
• Fittingswithmodernsealing ringsandsupport
functionsensure leak-proof, reusable connections.
• Monitor all air consumption. Countermeasures
areonlypossible if youknowhowmuch com-
pressedair isused.
