Laboratory Exhaust SystemsVektor-H
The Greenheck Vektor AdvantageThe Greenheck Vektor-H laboratory exhaust system is a better, lower cost alternative to a field built-up exhaust system.
• InstalledquicklyandeasilyonGreenheck’sreinforced roof curb model GPFHL
• Requireslessroofdeckspace
• Designedtowithstandupto125mphwind-loadswithoutguywires
• Acleanerinstallationwithfewerroofpenetrations
• Noperformancelossesduetofieldfabricatedinlet or outlet ducts
The Vektor®-Hisacost-effective,self-contained,highplumelaboratoryexhaustsystemdesignedtoremovehazardousornoxiousfumesfromalaboratory,dilutethefumeswithbypassairandexpelthemfromthelaboratorybuildingsothefumesdonotcontaminatetheroofareaorarere-entrainedintobuildingmake-upairsystems.
Benefits of the Vektor-H:• LicensedtobeartheAMCASealforSoundandAirPerformance
• Applicabletoconstantorvariablevolumeexhaustsystems
• MeetsANSIZ9.5,NFPA45andASHRAEguidelines
• Performancecapacitiesfrom270 - 24,000cfmandupto3.5 in. wgperfan (459–40,776m3/hrandupto875Pa)
• Configurableinsingle,doubleortriplefansystems
• SparkBresistantconstruction
GreenheckFanCorporationcertifiesthattheVektor-Hlaboratory exhaust fans shown herein are licensed to beartheAMCASeal.Theratingsshownarebasedontests and procedures performed in accordance with AMCAPublication211andAMCAPublication311andcomplywiththerequirementsoftheAMCACertifiedRatingsProgram.TheRatingsSealappliestosoundand air performance as shown in the Vektor-H Performancecatalog,00.LAB.NB002R21-2012
Ease of MaintenanceThe Vektor-H provides safe, easy inspection and maintenance of internal fan components.Byremovingoneaccess panel, service to the fanwheel,shaftandbearingassembly is accomplished withoutremovingthefanfromthe system.

Motor - Premiumefficient,standardNEMAframe,TEFCmotorwitha1.00servicefactoris standard.
Wheel - Abackward-inclined,non-overloadingwheelmanufacturedofweldedaluminum and coated with Hi-Pro Polyester.
Bypass Air Plenum (optional) - Facilitates the addition of ambient air to the exhaust airstream. The additional air increases the dilution of the exhaust air and also increases thedischargemomentumresultingingreaterdisplacementabovetheroof.Onvariablevolume systems, the bypass air plenum and damper allow reduction of lab exhaust volumebyaddingambientairtotheexhaustairstream.Thisallowsthefantorunataconstantspeedwithouttheneedforavariablefrequencydrive.Bypassairplenumsareconstructedofheavy-gaugeweldedsteelandarecoatedwithLabCoat.
Isolation Damper (optional) -Aparallelbladedamperusedtoallowmaintenanceon a fan while others are in operation. The isolation damper also prevents backflowonaredundantfanwhilethesystemisoperating.DampersarefabricatedofsteeloraluminumandarecoatedwithHi-ProPolyester.Controloptionsaregravityorelectric(2-position,springreturn)actuators.
Bypass Air Damper (optional) -Opposedbladedamperusedtobringambientair into the fan system for additional dilution or an increase in plume rise. DampersfabricatedofsteelarecoatedwithHi-ProPolyester.Controloptionsareelectricorpneumatic(modulating)oramanualquadrant.
Weatherhood - (optional - with Bypass Air Damper) Designedtoprotectthebypassairdamperandactuator(optional)fromrain,moisture,dust,anddirt.WeatherhoodsaremanufacturedfromweldedsteelandcoatedwithLabCoat.
Roof Curb - Astructuralsupportfabricatedof14gaugegalvanized/galvanealsteelstructurallyreinforcedtoprovideaminimumwind-loadratingof125mph(200km/hr)withouttheuseofguywiresontheinstalledVektor-Hsystem.
Drain Connection -Adrainconnectionlocatedatthebottomofthefanhousingallowsforremovalofanyrainorcondensation.Anadditionaldrain(standard)islocatedatthebottomofthebypassairplenum.
Fasteners - Allfastenersprovidedarestainlesssteelforadditionalcorrosion-resistant protection.
Spark-Resistant Construction -AllsizefansaremanufacturedtomeetAMCAtype“B”spark-resistantconstruction(aluminumwheelandshaftseal).
Bearings -(BeltDrive)-AirHandlingqualitybearingsinexcessofL10-100,000hourbearinglife(equaltoL50-500,000hrs).Nylonextendedlubelinesallowforfanbearinglubrication.
