The Davis #7747 Daytime Fan Aspirated Shield Kit is an economical solution for adding the benefits of fan aspiration to your wireless or cabled Vantage Pro2 or Vantage Pro2 Plus. Half the cost of the 24-hour fan-aspirated radiation shield, but nearly 75% as effective in reducing the effects of daytime radiation.
Solar-powered fan runs during the day. Since there is no backup battery, the the fan will cease running when night falls and the effects of radiation are less. Note that this kit is not compatible with the original Vantage Pro stations.
