VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm, execution 5

Low-pressure centrifugal fan of the VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm series for general industrial use, manufactured according to design scheme No. 5 with a V-belt drive, made of carbon steel.

This fan is designed for ventilation or air conditioning systems and other gas mixtures that do not contain fibrous materials, sticky substances, dust, and other solid impurities in an amount not exceeding 100 mg/m³ under conditions of moderate (U) climate (placement category 3) and tropical (T) climate (placement category 2).

The centrifugal fan VC 4-76 #16 consists of the following units, which can be purchased separately:

• fan VC 4-76 #16 without electric motor
• impeller of the fan VC 4-76 #16
• casing (housing) of the fan VC 4-76 #16
• Electric motor AIR 315 M6

Purpose of centrifugal fans VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm:

The centrifugal fan VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm is designed for moving air and other gas mixtures whose aggressiveness towards carbon steel does not exceed that of air, do not contain sticky substances, fibrous materials, as well as dust and other solid impurities in an amount not exceeding 100 mg/m³.

Centrifugal fans VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm are used in:

• air conditioning systems
• ventilation systems
• air heating systems
• for moving drying agent (heat carrier) in technological lines for grain drying with A1-DS50, A1-UZM grain dryers
• other sanitary and industrial purposes

The centrifugal fan VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm is operated in moderate climate conditions at ambient temperatures from -40°C to +40°C.

Operating principle of the centrifugal fan VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm:

Air, by transferring energy from the blades of the impeller, enters the fan under the influence of centrifugal force at a 90-degree angle and moves in a radial direction to the volute of the spiral casing; in the volute, moving along the spiral-shaped casing, under pressure, it is directed through the fan outlet.

Completeness of the centrifugal fan VC 4-76 #16 w/motor AIR 315 M6 132 kW 1000 rpm:

• spiral casing,
• impeller,
• frame,
• collector,
• electric motor.

The impeller consists of front and rear discs, 12 sheet blades, and a hub. The fan frame is welded. The base has a hole for installation on vibration isolators or a foundation. The electric motor and cover are mounted on the frame. The conical collector for supplying air to the impeller is fixed to the inlet pipe. The overlap between the collector and the front disc of the impeller is adjusted by axial movement of the collector in the inlet pipe.
