The solarfan circulates to 135 m³ of air per hour and can thus replace the air in a 10 m² greenhouse three to four times a day. In this process, humid air is also extracted, so that not only the internal temperature, but also the condensation is effectively reduced. The fan can be disabled at any time with the easy to use on/off switch. Available in five sizes, the solar fan fits in almost any Vitavia greenhouse. The Solarfan is simply mounted in place of glass in one of the roof vents and is suitable for: Ida, Neptune, Saturn, Orion, Cassandra and for Helena. NB! Suitable for IDA, Neptune, Jupiter, Saturn, Orion, Sirius, Cassandra and HELENA – please mind the measurements.The Vitavia Solarfan can NOT be fitted in the following greenhouse models without special adaptation, which the customer must perform: Zeus, Poseidon, Hera.
