Duct Installation

Bottom Inlet Duct Connection

The end of the duct (customer-supplied) is secured between the roof curb’s top edge and the curb cap of either the Vektor-H or bypass air plenum. If an isolation damper is present in the roof curb, the duct is located between the roof curb and the damper adapter tray.

Stack Extensions

Systems with multiple stack extensions require all sections assembled and installed on site between the main fan body and the discharge cone. Each section has guy wire attachment brackets located on the upper end of each section. The order sections are installed in are universal. Gasketing (3/16 x 1/2 inch with sticky back) is provided and is to be installed between each joining section.

Guy wires are required on system with multiple stack extensions. Location of connections, wiring and anchorage is determined by a structural engineer.

System Assembly

NOTE

When installing each section, be certain to rig each section separately using the lifting lugs provided.

1.Mount roof curb to roof deck in accordance with local codes.

2.Install 3/16-inch thick x 1/2-inch wide, closed-cell gasket on the top edge of the curb, adhesive side down (gasket provided). Leave no gaps between gasket sections to ensure tight seal.

3.Place the bypass air plenum (BAP) onto the previously installed gasket and secured roof curb. If a BAP is not provided for the unit, skip to Step 5. Pre-drill pilot holes into the roof curb and attach the BAP to the roof curb with mounting hardware (by others).

4.Install 3/16-inch thick x 1/2-inch wide, closed-cell gasket on the top edge of BAP, adhesive side down (gasket provided). Leave no gaps between gasket sections to ensure a tight seal.

5.Place the curb cap of the fan housing onto the gasket and BAP or onto roof curb if BAP is not provided. Attach the curb cap using the provided 5/16-inch self-tapping screws. If a BAP is not provided, pilot holes must be drilled into the roof curb.

6.Install the final nozzle subassemblies as shown in the submittal drawing. Align flange bolt holes and fasten sections using the 316 stainless steel bolts, washers, and lock washers provided.

7.Follow electrical connection and pre-start-up checks as listed on pages 7 and 8.

Vektor-HS, Vektor-H specifications

Greenheck Fan Corporation, a leader in air movement and control equipment, has developed the Vektor-H and Vektor-HS series to meet the growing demands for energy efficiency and performance in commercial and industrial ventilation systems. These models are specifically designed to provide optimal airflow while minimizing energy consumption.

The Vektor-H model stands out with its innovative backward-inclined centrifugal fan wheel, which effectively handles air volumes ranging from 1,000 to 150,000 CFM. This design minimizes turbulence and enhances performance, ensuring quiet operation even at high speeds. The Vektor-H also features a direct drive option that eliminates the need for belts and sheaves, reducing maintenance while increasing reliability. The inclusion of a high-efficiency motor further exemplifies its commitment to energy savings.

On the other hand, the Vektor-HS, or High-Static version, is designed for applications requiring higher static pressure. This capability makes it ideal for systems where long duct runs or highly restrictive applications are involved. With airflow capabilities similar to the Vektor-H, the Vektor-HS is capable of operating efficiently in conditions that demand advanced pressure performance.

Both models come equipped with Greenheck’s advanced controls and monitoring systems, which provide real-time data on performance metrics. These features allow facility managers to optimize the system based on actual operating conditions, thereby improving energy efficiency and reducing operational costs.

Technologically, the Vektor-H and Vektor-HS series utilize advanced acoustic design principles, which significantly reduce noise levels. The application of sound-dampening materials and strategically designed fan casings helps in achieving a quieter working environment, addressing one of the common concerns in HVAC systems.

Furthermore, the Greenheck Vektor series is built with durability in mind. The construction involves heavy-gauge steel and corrosion-resistant finishes, ensuring long-lasting performance even in harsh environments. Both the Vektor-H and Vektor-HS are also customizable, allowing for modifications to meet specific application requirements, such as different mounting configurations and discharge orientations.

In summary, the Greenheck Vektor-H and Vektor-HS series represent the fusion of advanced technology with practical applications, resulting in efficient, durable, and quiet ventilation solutions suitable for a variety of industrial and commercial settings. These models not only address the current needs for energy efficiency and performance but also position users favorably for future advancements in HVAC technology.
