VC 4-75 #10 w/motor AIR 160 S8 7.5 kW 750 rpm, execution 1

Series VC 4-75 #10 low-pressure centrifugal fan (VR 88-72.1-5.5, VR 80-75-5) with electric motor Electric motor AIR 160 S8 7.5 Power kW 750 Vol./Min, general-purpose design, execution scheme № 5 with V-belt drive, made of carbon steel.

Intended Application:

This fan is designed for ventilation or air-conditioning systems and other gas mixtures whose corrosiveness to carbon steel does not exceed that of air at up to 80 °C, and that contain no fibrous materials, sticky substances, dust, or other solid impurities in excess of 100 mg/m³ under moderate (U) climate (placement category 3) and tropical (T) climate (placement category 2) conditions in accordance with DSTU 15150.

Modular Components (available separately):

• Fan assembly VC 4-75 #10 without electric motor
• Impeller wheel VC 4-75 #10 (VR 88-72.1-5.5)
• Scroll casing VC 4-75 #10 (VR 80-75-5)
• Electric motor Electric motor AIR 160 S8 7.5 Power kW 750 Vol./Min for fan VC 4-75 #10

General Characteristics of Series VC 4-75 #10 w/motor AIR 160 S8 7.5 kW 750 rpm (VR 88-72.1-5.5, VR 80-75-5):

• Low pressure
• Single-sided suction
• Backward-curved blades
• Number of blades: 12
• Direction of rotation: right and left
• Execution scheme: № 5 (V-belt drive with V-belts and drive/driven pulleys)
• Manufactured according to TU U 28.2-24881057-003:2023

Applications:

• Air-conditioning systems
• Ventilation systems
• Air-heating systems
• Other sanitary and industrial purposes

Operating Conditions:

Operates in moderate climate conditions at ambient temperatures from −40 °C to +40 °C. The temperature of the conveyed medium must not exceed 80 °C.

Principle of Operation:

Air, by energy imparted by the impeller blades, enters the fan under centrifugal force at a 90° angle and is directed radially into the scroll-shaped casing; within the casing, the pressurized air follows a spiral path and is discharged through the fan outlet.

Delivery Set:

• Scroll-shaped casing
• Impeller wheel (front/rear discs, 12 blades, hub)
• Support frame (welded stand with mounting hole for vibration isolators or foundation)
• Collector (conical, attached to inlet nozzle; overlap adjusted by axial movement)
• Electric motor Electric motor AIR 160 S8 7.5 Power kW 750 Vol./Min

Position of Radial Fan Housing (viewed from suction side):

• Right rotation (PR)
• Left rotation (LIV)

Placement Categories (climatic conditions):

1. 1st category: open air (exposed to natural climatic factors).
2. 2nd category: under a canopy or semi-enclosed spaces with conditions close to outdoors but without direct precipitation or sunlight.
3. 3rd category: enclosed spaces with natural ventilation and minor temperature/humidity fluctuations; low dust and sand levels.
4. 4th category: artificially regulated climate (heated/cooled and ventilated industrial premises or well-ventilated underground spaces).
5. 5th category: high-humidity spaces (e.g., unheated/uneventilated basements, mines, holds, areas with frequent condensation).
