 3 PRESENTATION
TheMAXITOPceilinginstalledltraonunitisadustcollectorwithpulsecleanedltraonthat
cleansthewholesurfaceofthecartridges.Thedustcollectoroershigheciencywhilerequiring
lowenergyconsumpon.Thecartridgesarecleanedonerowatameandinsequence.
The MAXITOP dust collector is largely used where airborne pollutants are a nuisance. Main
applicaonsarewelding,bungandsanding,pharmaceucalandfoodplants,handlingofvolale
parcles,etc.
The MAXITOP unit can be equipped with or without fume arms, pulse with mer board or
dierenalpressurecontroler,etc.
 3.1 EachMAXITOPdustcollectorincludes:
• 10and14gaugesteelcabinetwithaluminumprimerandpolyurethanepaint.
• Air inlet and outlet
• Directdrivefan.
• Controlpanelforautomacpulsecleaning

• Lilugsaslousedforceilingorwallsupport
• Valvesanddiaphragms
TheMAXITOPunitmaybedeliveredfullyassembledbutminimaleldassemblymayberequired.
Thecleaningsystemelectricalconneconwillneedtobeperformedatthejobsitewheninstalling
the dust collector.

 5 NORMALUSE
 5.1 Start-upwithnewcartridges
Donotusethecompressedaircleaningsystemunlthepressuredierenalacrossthecartridges
hasincreasedtoatleast1inchW.G.incomparisontothestarngpressure.Thecleaningsequence
shouldbekeptata45to60seconddelaybetweenpulses.Whenthepressuredierenalincreases
to2inchesW.G.,thefrequencybetweenpulsesmaybereducedinordertomaintain2inchesW.G.
dierenal.Thedustcollectorcanworkatdesignairvolumeaeronedayofoperaon.
Note:starngairvolumewillbegreaterthandesignairvolume.Amperagedrawwillbehigher
than design.
 5.2 Normalstart-up(withusedcartridges)
Oncethedustcollectorhasreachednormaloperangcondions,every day start-up is done
withoutadjustment.
 5.3 Pressuredierenal
Thenormaloperangpressuredierenalshouldvary from 0.75 to 4.0 inch W.G.forpaper
cartridges,andfrom0.70to4.0inchW.Gforpolyestercartridges(dependingoncollecteddustand
airtoclothrao).Ifthedesignedpressuredierenalcannotbemaintained,thepulsefrequency
mustbechanged.Thepulsefrequencycanbeincreasedordecreasedbyturningtheadjustment
screwontheelectronicsequencerboard.
 6 OPERATIONANDPURPOSE
Duringnormaloperaon,theMAXITOPunitdrawspollutantsthroughtheMAXAIRfumearms(if
ordered)orthroughtheinletgrillesifusedforambiantaircleaning.Theautomacpulsecontrol
cleansthecartridgesatregularintervals.Cleanaircanthenberecycledinthefacilityifdesired.
