Congratulations,theComcoAccuFlo®modelAF10‐Eyouhavepurchasedincorporatesthelatest
developmentinmicro‐abrasiveblasting– Simoom®technology.
Thispatentedmethodofmixingairandabrasivesdeliversasteadier,more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.
HowdoesSimoom®technologywork?
Activated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.
