Gripping
• Thegrippermust be correctlysized.Oversized
grippers consumemore compressedair than
necessary.
• Useshortest possible tubing lengths, i.e. position
thevalveas closeaspossible to thegripper.
• Pleasenote that deadvolume in the tubing fre-
quentlyaccounts for a largepercentageof overall
consumption, especiallywheregrippingwith
small volumes is involved!
• Usepneumaticgrippers inmovingapplications.
Theyare lighter thanelectricgrippers, and they
reduceweight andsaveenergyasa result.
• Usepneumaticgrippers for longholding times.
Withpneumaticgrippers, gripping force isavaila-
ble for as longasneeded–without anyadditional
energy consumption. Electricgrippersare con-
trolledand requireadditional holding current.
Vacuum
Install thevacuumgenerator as closeaspossible
to theapplication.
Vacuumsuctionnozzlesare the ideal solution for
thispurpose.
• Avoid long tubing linesbetween thevacuum
generator and thesuctiongripper.
• Powerful vacuumor highsuction rate?Select the
right suctionnozzles for theapplication inques-
tion.
• Short evacuation times reduceair consumption
at thevacuumgenerator.
• Vacuumgeneratorswithair-saving circuit are
capableof saving largeamountsof compressed
air inmany cases.
• Checkexhaust air silencers invacuumgenerators
for contaminationona regular basis!
Of course theextensiveproduct range from Festoalso includesperfectlymatchedmechanical andvacuum
grippers for the front unit. Insome cases this results inmassiveenergy-savingpotential.
