The fans comprise a housing and an electric motor with impeller.
A differentiation is made between axial, radial and cross-flow fans. Typical motors are self-starting shaded-pole motors or capacitor motors.
Fans possess a long service life thanks to their robust construction.
The selection criterion for fans is the required air flow. Small fan cross-sections and high throughputs lead to high (air) flow speeds and thus to higher noise levels. |
