Greenheck’s Vektor-H® high plume laboratory exhaust systems in single- and two-fan configurations can now be specified with a factory-programmed controls package. The independent control system maintains duct static pressure by modulating fan speed, bypass damper position, and isolation dampers as selected in Greenheck’s Computer Aided Product Selection program (CAPS®). The control system includes variable frequency drives (VFDs), a duct sensor, and a separate factory-programmed logic controller (PLC). It can operate as a standalone or integrate with a building management system using BACnet. With performance capacities up to 26,000 cfm and up to 4 inches of water column, the Vektor-H bears the AMCA Seal for Sound and Air Performance, Miami-Dade NOA Certification, and Florida Product Approval.
