Congratulations,theComcoAccuFlo®modelAF10‐CEyouhavepurchasedincorporatesthelatest
developmentinmicro‐abrasiveblasting– SimoomTechnology.
Thispatentedmethodofmixingairandabrasivedeliversasteadyandconsistentstreamof
abrasiveallowingyoutoprocesspartsefficientlyandwithuniformresults.Here’swhyitworksso
muchbetterthanothermicro‐abrasiveblasters.
Activatetheblastandthemodulatoropensandcloses50or60timespersecond(dependingon
localpowersuppliedat50Hzor60Hz),producingpulsesintheairstream.Therapidchangeinair
pressurefluidizestheabrasiveabovetheorifice.Thepowderisthendrawnthroughtheorifice
intothemixingchamberwhereitenterstheairstreamandexitstheAccuFlo®throughthe
PowderGate®valvetravelingouttothenozzle.
Thestrengthofthesemodulatedpulseandthediameteroftheorificedeterminestheamountof
abrasivethatdropsintothemixingchamber.Threemechanismsenableyoutochangetheamount
ofabrasiveintheairstream:thetankorifice,abrasiveblendandbypasstube.
TankOrifice:Alargerorificeincreasesabrasiveflow.Inmostcasestheorificeshouldbeatleast5
timesthesizeoftheaverageparticlesize,butnotlargerthanthenozzle.
BypassTube: Thebypasstubecreatesanalternatepathforthemodulatorpulses,bypassingthe
orifice.Alargerbypasstubedampenstheimpactofeachpulse,reducingmediaflow.
AbrasiveBlend:Theabrasiveblendchangesthestrengthofthepulsebyallowingsomeairto
bypassthemodulator.Withlessairpassingthroughthemodulator,thepulseweakensandless
abrasiveisfedintotheairstream.Theabrasiveblendvalveallowsyoutofinetunetheabrasive
flow.

CablingandcontroldependsonhowtheuserdesirestocontroltheAF10‐CE.Usetheabovetable
todeterminewhichcabletouse.IftheAF10‐CEispairedwithanAutoFillunit,refertotheAutoFill
manualforadditionalwiringinformation.
BlastControl:Pin1provides115VACpowerfromtheAccuFlo.Thehostmustprovideaswitchto
putthisvoltagebackintoPin2,whichwillcausetheblastertoblast.WhenPin2isleftfloating,
theblasterwillnotblast.200mAofcurrentistypical.
PE: Pin4providesanoptionalbondingpathtoPrimaryEarththroughtheAccuFlo.Ifthehostis
otherwisebondedtoPE,donotusethispin.
RegulatorControl:Theregulatormustbepoweredby24vdcthroughPin7andgroundthroughPin

atPin8,whichcorrespondstoapressureof0‐148psi.Theinternalresistanceoftheregulator’s

TheCYC countsthenumberofblastcycleson
theAccuFlo (eachtimethePowderGate®

Abrasivetypeandblastpressurewillimpact
maintenancefrequency,buttypical

Iftheunitdoesnotpressurizewhenyouturniton:
•Istherepowertotheunit?Doesthelightonthepowerswitchilluminate?
Ifnot,checkthepowercordconnectionsatthebackoftheunitandatthepowersource.Check
thefuse.
•Istheairlineconnected?Aretheupstreamvalvesopen?
Checktheinletairsupply.
•Doyouhearairescapingfromtheunitwhenitisturnedon?
Checkthattheinletair,venthose,andabrasivehoseexitingthePowderGate®valveare
connectedproperly.Seetheset‐upguideonpages4‐5.Makesurethetankcoverissecurely
fastened.
Ifairispassingthroughthenozzle,butnoabrasive;orifthecuttingactiondecreases:
•Isthepowdertankempty?Refill.
•Istheabrasiveinthetankdampandstickingtothewalls?
Replacewithfreshpowder.Checkthatyourairdryerisworkingproperly.
•Isthetankorificeplugged?
Emptypowder,removeorifice,andinspect.Checktoseethatyoursupplierofabrasivepowder
isprovidinghighqualitymaterial.
FordetailsseetheSupportsectiononourwebsite.
•Isyourmodulatorfunctioningproperly?
Youshouldhearabuzzingsoundwhentheblastisactivated.Ifnot,themodulatormayneedto
bereplaced.ForfurtherdetailscontactTechnicalSupport.
Ifnothinghappenswhentheblastisactivated:
•Isthenozzleplugged?Removeandinspect.
•IsthePowderGate®valvefailingtoopen?ContactTechnicalSupport.
IfyoususpectthePowderGate®valveisnotclosingcompletely:
WhenthePowderGate®valvecloses,placeafingerovertheendofthenozzlefor3seconds.
Whenyouremoveyourfinger– isthereasmallpuffofair?Ifso,therearetwopossibilities:
•ThePowderGate®noseiswornandcanbereplacedasdescribedabove.
•Theabrasivemixturemaybetoorich.ReduceAbrasiveBlendadjustmentonfrontpanel,or
checktheBypassTubeChartforaleanermixturetohandleyournozzlesize.
Troubleshooting
Contaminationoftheabrasivepowderfrom
moistureand/oroilisoneofthemost
commonproblemsassociatedwithmicro‐
abrasiveblasting.
Moisturewillcausethepowderto“clump
up,”preventingitfromflowingfreelyfrom
thetank.
Oilintheairsupplywillnotonlyaffect
abrasiveflow,itcanalsocausemajor
componentfailureswithinyourblaster,
resultingincostlyrepairs.
Toavoidmoistureandoilcontamination,run
yourairsupplythroughapositiveairdryer
equippedwithanappropriateoilfilter.
