Centrifugal fans VC 14-46 #2.5 w/motor AIR 63 B4 0.37 kW 1500 rpm (VR-287-46.1) are used:

• In air conditioning systems
• In ventilation systems
• In air heating systems
• For other sanitary and industrial purposes

The centrifugal fan VC 14-46 #2.5 w/motor AIR 63 B4 0.37 kW 1500 rpm (VR-287-46.1) with the Electric motor AIR 63 B4 0.37 Power kW 1500 Vol./Min electric motor is operated in moderate climates, at ambient temperatures from -40 °C to +40 °C. The temperature of the transported medium must not exceed 80 °C.

Operating principle of the centrifugal fan VC 14-46 #2.5 w/motor AIR 63 B4 0.37 kW 1500 rpm (VR-287-46.1):

Air, receiving energy from the impeller blades, enters the fan under the action of centrifugal force at an angle of 90 degrees and flows radially into the spiral housing; in the housing, moving along the spiral-shaped casing, it is directed under pressure through the fan outlet.

Composition of the centrifugal fan VC 14-46 #2.5 w/motor AIR 63 B4 0.37 kW 1500 rpm (VR-287-46.1) with the Electric motor AIR 63 B4 0.37 Power kW 1500 Vol./Min electric motor:

The VC 14-46 #2,5 (VR-287-46.1) fan, equipped with the Electric motor AIR 63 B4 0.37 Power kW 1500 Vol./Min electric motor, consists of the following main units:

• Spiral housing
• Impeller
• Base frame
• Collector
• Electric motor Electric motor AIR 63 B4 0.37 Power kW 1500 Vol./Min

The impeller consists of a front and rear disc, 32 sheet blades, and a hub.

The fan base is welded. The base has a hole for installation on vibration isolators or a foundation. The electric motor and the cover are mounted on the base frame.

The conical collector for air supply to the impeller is mounted on the inlet pipe. The overlap between the collector and the front disc of the impeller is regulated by axial movement of the collector in the inlet pipe.

• a) right rotation
• b) left rotation

Note on placement categories depending on climatic conditions:

• Category 1: For outdoor operation (exposed to a set of climatic factors characteristic of the respective macroclimatic regions).
• Category 2: For operation under a shelter or in rooms where temperature and humidity fluctuations do not significantly differ from outdoor conditions and there is relatively free access to outside air, e.g., tents, van bodies, trailers, uninsulated metal rooms, as well as the enclosure of complete products of category 1 (no direct exposure to sunlight or precipitation).
• Category 3: For operation indoors with natural ventilation without artificially controlled climate conditions, where temperature and humidity fluctuations and exposure to sand and dust are much less than outdoors, e.g., insulated metal, stone, concrete, wooden premises (no exposure to precipitation, direct sunlight; significant reduction in wind, scattered solar radiation and moisture condensation).
• Category 4: For operation in rooms with artificially controlled climate conditions, e.g., heated or cooled and ventilated production premises, rooms with conditioned or partially conditioned air, including well-ventilated underground rooms (no exposure to direct sunlight, precipitation, wind, sand, or outdoor dust; no or significantly reduced exposure to scattered solar radiation and moisture condensation).
• Category 5: For operation in rooms with high humidity (e.g., unheated and unventilated underground rooms, including mines, basements, soil, ship holds and other rooms where water may be present for long periods or frequent moisture condensation on walls and ceilings, such as in certain textile, hydrometallurgical workshops, etc.).
