Greenheck Expands Laboratory and Fume Exhaust Fan Line with Two New Models
Greenheck's Vektor line of high plume laboratory and fume exhaust systems has expanded with the addition of two new models. The Vektor-CH utilizes an engineered high velocity discharge nozzle that efficiently exhausts air high above the roof. In combination with a centrifugal blower, the Vektor-CH achieves high pressures and flow rates commonly required by fume exhaust systems. 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 and safe discharge velocity (minimum 3,000 ft./min. per ANSI Z9.5).
Vektor-CS is available in four model sizes 33-44 with performance capabilities of 10,000 to 38,500 cfm, and up to 14 in. wg. Vektor-CH performance capabilities of 10,000 to 60,000 cfm and up to 14 in. wg. Both have an efficient centrifugal airfoil wheel and air handling quantity bearings, can withstand a 125 mph wind load without guy wires, and comply with ANSI and NFPA standards for laboratory exhaust applications.
