alternative name:
Dayton Fan and Motor Co.
Abbreviation: dayfan
Products: Model types

Day-Fan began business as Dayton Fan & Motor Company in 1889 producing fans. Radio parts were produced from 1922 and complete radios from 1924.

In 1929 or 1930 General Motors purchased Dayfan Radio. They produced under Delco. In response of an anti trust suit filed by the dept of justice in May 1930 RCA and General Motors liquidated GM Radio about Nov 1931.

Trade Name: "Daycroft" "Dayroyal"

Founded: 1889
Closed: 1929
Production: 1922 - 1929

Rider´s and the Radios Collectors Guide listings allocate Day-Fan to General Motors. But Day-Fan models were not made under GM! The Radio Collectors Guide (Grinder/Fathauer) and Rider´s are obviously incorrect! See Slusser/Bunis.

Please allocate all Models pre 1929 at Day-Fan.
All other post 1929 Models at General Motors/ United Motors/ D

1889 wurde die Dayton Fan & Motor Company gegründet. Produziert wurden Ventilatoren. 1922 begann die Herstellung von Radio-Bauteilen und ab 1924 von kompletten Radiogeräten. 1929 wurde die Firma von General Motors aufgekauft. Rider´s Perpetual und (wohl daraus später folgend) Radio Collectors Guide führen die Firma fälschlich unter General Motors. Es gibt aber nach 1929 keine Dayfan Modelle mehr. Es wurde unter der GM-Marke Delco produziert (gleiche Adresse!), und diese läuft unter United Motor Service (Delco).
