General Characteristics of Series VC 4-75 #10 w/motor AIR 160 M8 11 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

- 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 M8 11.0 Power kW 750 Vol./Min
Position of Radial Fan Housing (viewed from suction side):
- Right rotation (PR)
- Left rotation (LIV)

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