Fans are manufactured in accordance
with TU U 28.2-24881057-003:2023:

from carbon steel;
from stainless steel;
from dissimilar metals;
from aluminum alloys;
from titanium alloys.

VC 4-75 Low-pressure radial fan is the most popular type of ventilation equipment.

The fans are intended for use in rooms where the concentration in the moving air stream of solid mechanical dust impurities does not exceed 100 mg/m3 with a temperature up to +80 °C and in the absence of any impurities having a fibrous structure or sticky properties.

VC 4-75 fans are used:

in air conditioning systems;
in ventilation systems;
in air heating systems;
for other sanitation-production purposes.

General information about fans:

Single suction;
Spiral rotary body;
Backward curved blades;
Quantity of blades 12;
Direction of rotation – right and left.

Depending on the direction of rotation, the fans are produced in the right or left rotation. Right-hand fans with a wheel rotating clockwise, left rotation – with a wheel rotating counter-clockwise when viewed from the suction side of the fan.
