Plume laboratory and fume exhaust fan
Vektor-CH and Vektor-CS fans are added to Greenheck Vektor's plume laboratory and fume exhaust systems line.
Greenheck Vektor adds two models for its plume laboratory and fume exhaust systems line. The Vektor-CH features a high velocity discharge nozzle that exhausts air above the roof. In combination with a centrifugal blower, the Vektor-CH has high pressures and flow rates. With multiple discharge nozzles available per size, Vektor-CH can be specified for project-specific requirements, reducing first costs and operating costs. The Vektor-CS employs a variable geometry nozzle that maintains a constant discharge velocity, while constant duct static pressure is maintained by adjusting the fan speed with a variable frequency drive. As airflow through the fan varies, the nozzle discharge area automatically adjusts to maintain a constant discharge velocity (minimum 3,000 ft/min per ANSI Z9.5).
