[Stoves] air for gazification

[Boll, Martin Dr.]

Dear Frank,
I googled, and found several data-sheets for different
computer-ventilator-types. 
Look there around starting from: (Lüfter = ventilator)
http://www.bedek.de/Datenblaetter.53.0.html

(Lüfter = ventilator)
(If you get odd writings of the word: The other way to write Lüfter when the
original type is missing: Luefter)

Best regards

Martin
