Laboratory Exhaust SystemsVektor™-H

Advantages of the Vektor-HThe 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

• Designedtowithstandupto125mphwindloadswithoutguywires

• Acleanerinstallationwithfewerroofpenetrations

• Noperformancelossesduetofieldfabricatedinlet ducts and outlet

TheVektor-Hisacost-effective,self-containedhighplumelaboratoryexhaustsystemdesignedtoremovehazardousornoxiousfumesfromalaboratory,dilutethefumeswithbypassairandexpelthemfromthelabbuildingsothefumesdonotcontaminatetheroofareaorarere-entrainedintobuildingmake-upairsystems.

Benefits of the Vektor-H:• LicensedtobeartheAMCASealforSoundandAirperformance

• Applicabletoconstantorvariablevolumeexhaustsystems

• MeetsANSIZ9.5,NFPA45andASHRAEguidelines

• Performancecapacitiesfrom270-24,000cfmandupto3.5in.wgperfan (460–40,800m3/hrandupto875Pa)

• Configurableinsingle,doubleortriplefansystems

• SparkBresistantconstruction

GreenheckFanCorporationcertifiesthattheModelVektor-Hlaboratory exhaust fans shown herein are licensed to bear theAMCAseal.TheratingsshownarebasedontestsandproceduresperformedinaccordancewithAMCAPublication211andPublication311andcomplywiththerequirementsoftheAMCACertifiedRatingsProgram.TheRatingsSealapplies to sound and air performance as shown in the Vektor-H PerformanceRev.1November2005catalog.

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.
