HABERLANDSTR. 10 Gentlemen, you know perfectly well how dangerous all dust is to the moving parts of an explosion motor. We beg to offer a small cheap apparatus, the "Filtrator", which removes ca 98% of all dust from the suction air by making the dusty air pass over large wetted surfaces. The "Filtrator" represents a new process of dust-removing discovered only recently, whose efficiency exceeds that of all others (e.g. clothfilters) about twentyfold. The "Filtrator" is suitable for every make and every motor and can easily and quickly be fitted. The "Filtrator" should not be missing in any motor car, motor plough, motor bicycle, flying machine or stationary explosion motor. We shall gladly supply samples if cash payment be made beforehand. In consideration of the great advantages of the "Filtrator" for all kinds explosion motors high class firms at home and abroad have already taken up the "Filtrator". Yours very truly Walter Fricke | ||
