Impeller of the fan VC 6-28 (VR 120-28) #5:

The impeller is of turbine type and has 16 blades. The blades are welded to the front and rear discs. The rear disc is attached to the hub by casting. The discs and blades are made of sheet steel, and the hub is made of gray cast iron. The impeller is designed to create a vacuum in the suction area and overpressure in the discharge area. The impeller can be right or left rotating.

Spiral housing of the high-pressure fan VC 6-28 (VR 120-28) #5:

The spiral housing is welded from sheet and shaped steel. It can be of left or right rotation. The surfaces of the impeller and the spiral housing that come into contact with the transported medium form the flow cavity. The purpose of the housing is to form the suction and discharge flows.

Asynchronous electric motor Electric motor AIR 112 M2:

The Electric motor AIR 112 M2 motor is a general-purpose asynchronous three-phase motor with a squirrel-cage rotor, designed to operate from an AC network with a frequency of 50 Hz and a voltage of 220/380 V. The rated speed of the Electric motor AIR 112 M2 motor is 3000 rpm. Frame size (shaft height): 112 mm; shaft diameter: 32 mm; power in kW: 7.5; climate version: UZ; IP rating: 54. The housing of AIR motors with a power of 1.5 kW or more is cast from gray cast iron for reliability. Upon request, the Electric motor AIR 112 M2 motor can be supplied with a housing made of silumin alloy.
