Greenheck Expands Laboratory and Fume Exhaust Fan Line
15 January 2015

Greenheck’s Vektor® line of high plume laboratory and fume exhaust systems has been expanded with the addition of two new models. The Vektor®-CH utilizes an engineered high velocity discharge nozzle that exhausts air high above the roof.
In combination with a centrifugal blower, it achieves high pressures and flow rates commonly required by fume exhaust systems. With multiple discharge nozzles available, it can be specified for project-specific requirements. 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 and safe discharge velocity (minimum 3,000 fpm per ANSI Z9.5). Vektor–CS is available in four models with performance capabilities of 10,000 to 38,500 cfm and up to 14 in.wg. Vektor-CH has performance capabilities of 10,000 to 60,000 cfm and up to 14 in.wg. Both have centrifugal airfoil wheels and can withstand 125 mph wind load without guy wires, and comply with ANSI and NFPA standards for laboratory exhaust applications.
