Receiving, Unpacking, Handling, Storage

Receiving

Greenheck model Vektor-H and Vektor-HS fans are thoroughly inspected, test run at the factory, and shipped on a skid or packaged to minimize damage during shipment. The transportation carrier has the responsibility of delivering all items in their original condition as received from Greenheck. The individual receiving the equipment is responsible for inspecting the unit for obvious or hidden damage and recording any damage on the bill of lading before acceptance of the equipment. All claims (if necessary) shall be ﬁled with the ﬁnal carrier.

Unpacking

Verify that all required parts and the correct quantity of each item have been received, including accessory kit containing gasketing, etc. If any items are missing, report shortages to your local representative to arrange for obtaining missing parts. Sometimes it is not possible that all items for the unit be shipped together due to availability of transportation and truck space. Conﬁrmation of shipment(s) must be limited to only items on the bill of lading.

Handling

The Vektor-H and Vektor-HS laboratory exhaust system is shipped in subassembly sections for easy rigging and installation. Depending on the fan size, the sections can include: Blower Assembly, Stack Extension, and Discharge Nozzle.

The Vektor-H and Vektor-HS are designed to be self- supporting and standing (without the use of guy wires) when assembled per the instructions provided within this manual. All subassembly sections have lifting lugs as shown.

Storage

Fans are protected against damage during shipment. If the unit cannot be installed and operated immediately, precautions need to be taken to prevent deterioration of the unit during storage. The user assumes responsibility of the fan and accessories while in storage. The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user.

INDOOR

The ideal environment for the storage of fans and accessories is indoors, above grade, in a low humidity atmosphere which is sealed to prevent the entry of blowing dust, rain, or snow. Temperatures should

be evenly maintained between 30° and 110°F. (-1°C and 43°C). Wide temperature swings may cause condensation and “sweating” of metal parts. All accessories must be stored indoors in a clean, dry atmosphere.

Remove any accumulations of dirt, water, ice or snow and wipe dry before moving to indoor storage. To avoid “sweating” of metal parts allow cold parts to reach room temperature. To dry parts and packages use a portable electric heater to get rid of any moisture build up. Leave coverings loose to permit air circulation and to allow for periodic inspection.

The unit should be stored at least 3½ in. (89 mm) off the ﬂoor on wooden blocks covered with moisture proof paper or polyethylene sheathing. Aisles between parts and along all walls should be provided to permit air circulation and space for inspection.

OUTDOOR

Fans designed for outdoor applications may be stored outdoors, if absolutely necessary. Roads or aisles for portable cranes and hauling equipment are needed.

The fan should be placed on a level surface to prevent water from leaking into the fan. The fan should be elevated on an adequate number of wooden blocks so that it is above water and snow levels and has enough blocking to prevent it from settling into soft ground. Locate parts far enough apart to permit air circulation, sunlight, and space for periodic inspection. To minimize water accumulation, place all fan parts on blocking supports so that rain water will run off.

Do not cover parts with plastic ﬁlm or tarps as these cause condensation of moisture from the air passing through heating and cooling cycles.

Fan wheels should be blocked to prevent spinning caused by strong winds.

Inspection and Maintenance during Storage

While in storage, inspect fans once per month. Keep a record of inspection and maintenance performed; see backcover.

If moisture or dirt accumulations are found on parts, the source should be located and eliminated. At each inspection, rotate the wheel by hand ten to ﬁfteen revolutions to distribute lubricant on motor and bearings. If paint deterioration begins, consideration should be given to touch-up or repainting. Fans with special coatings may require special techniques for touch-up or repair.

Machined parts coated with rust preventive coating should be restored to good condition promptly if signs of rust occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lint-free cloths. Polish any remaining rust from surface with crocus cloth or ﬁne emery paper and oil. Do not destroy the continuity of the surfaces. Wipe clean thoroughly with Tectyl® 506 (Ashland Inc.) or the equivalent. For hard to reach internal surfaces or for occasional use, consider using Tectyl® 511M Rust Preventive or WD-40® or the equivalent.

2 Laboratory Exhaust System

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.
