Extractor hood

Belongs to:
Kitchenware and household appliances
Synonyms:
Extractor fan
Description:

An extractor hood is an electrically driven device for extracting cooking or baking vapor. In some cases, an additional fan is integrated. The alternating electric and magnetic fields at the fundamental frequency of 50 Hz resp. 60 Hz are caused by the operation of the filter or resp. the fan.

Frequency ranges:
  • 50–60 Hz
Type of field:
electric and magnetic
