VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm, execution 1

Medium-pressure centrifugal fan of the VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm series (VR-287-46.1) for general industrial use, made of carbon steel.

The VC 14-46 #8 fan is a medium-pressure fan designed for both ventilation systems and air conditioning systems, as well as for other gas mixtures whose aggressiveness towards carbon steel does not exceed that of air, with temperatures up to 80°C. It must not contain sticky substances, fibrous materials, dust, or other solid impurities in an amount exceeding 100 mg/m³, under moderate (U) climate conditions (placement category 3) and tropical (T) climate (placement category 2).

This model is an analogue of medium-pressure centrifugal fans VR-287-46.1, VR 320-46, VR-300-46, VR 300-45, VR 289-46, VR 15-45.

The centrifugal fan VC 14-46 #8 (VR-287-46.1) consists of the following units, which can be purchased separately:

Purpose of centrifugal fans VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm (VR-287-46.1):

The centrifugal fan VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm is designed for moving air and other gas mixtures whose aggressiveness towards carbon steel does not exceed that of air, not containing sticky substances, fibrous materials, as well as dust and other solid impurities in an amount not exceeding 100 mg/m³.

Centrifugal fans VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm (VR-287-46.1) are used in:

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

The centrifugal fan VC 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm (VR-287-46.1) operates under moderate climate conditions 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 #8 w/motor AIR 225 M8 30 kW 750 rpm (VR-287-46.1):

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 14-46 #8 w/motor AIR 225 M8 30 kW 750 rpm (VR-287-46.1):

• spiral casing,
• impeller,
• frame,
• collector,
• Electric motor AIR 225 M8

The impeller consists of front and rear discs, 32 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.
