We have been an authorized dealer for Cigar Oasis products for over 20 years! Cigar Oasis units were designed to make life easier for the cigar smoker. This is the Auxiliary Fan Kit for the Cigar Oasis Excel 3.0 to improve air flow. This fan kit is designed to work with the Magna, Plus and Excel 3.0 models. These kits do not work with the legacy Cigar Oasis II, IIXL, Magna or Magna 2.0 units. Note: The brand of the fans may be different from that of the image. These fan kits all come directly from Cigar Oasis and are the correct ones for use with your 3.0 series humidifier.
