Davis Daytime Fan Aspirated Radiation Shield Kit

The Davis Daytime Fan Aspirated Radiation Shield Kit enhances temperature measurement accuracy on Vantage Pro2 and Pro2 Plus weather stations by reducing solar radiation errors during daylight hours. This cost-effective alternative to 24-hour fan aspiration systems delivers nearly 75% of the radiation-shielding effectiveness at half the price, making it an ideal upgrade for boaters, marine researchers, and coastal weather monitoring applications where daytime thermal accuracy is critical.

The kit features a solar-powered fan that operates automatically during daylight hours, eliminating the need for external power or backup batteries during daytime operation. Because solar radiation effects diminish significantly after sunset, the fan's daytime-only cycle matches the actual thermal protection needs of most monitoring scenarios. The integrated solar panel charges during the day and powers the fan continuously while sunlight is available, then ceases operation at night when radiation-induced errors are minimal. This design balances performance with simplicity, delivering measurable improvements in sensor accuracy without the complexity and higher cost of continuous 24-hour aspiration systems.

This kit is suited for marine installations, coastal weather stations, and any outdoor monitoring where daytime temperature precision matters—from recreational boating weather tracking to professional marine environmental data collection. Weighing just 2.6 lbs with compact dimensions of 10 x 7 x 12 inches, the shield mounts easily on existing Vantage Pro2 systems without requiring station relocation or complex installation modifications. Weekend fishermen upgrading personal weather stations and serious offshore operations collecting water-temperature-correlated atmospheric data alike benefit from reduced solar heating artifacts in their temperature readings.
