Model VENModel VENThe Eppley Ventilator is designed to be used with the Precision Spectral Pyranometer, Model PSP or the Precision Infrared Radiometer, Model PIR.
A "muffin" fan in the base continuously blows air over both the instrument case and the instrument dome, keeping the hemispheres cleaner from frost, snow, dew and moisture buildup. The fan provides approximately 30 C FM of ventilation and draws approximately 0.15 amps, or 11 watts, in the 115 volt configuration. The clear plastic upper housing allows the instrument, connector, and desiccator window to be easily viewed. A white enameled guard disk, leveling screws and hold down holes are provided. The 8 inch diameter, 5.75 inch high ventilator weighs 5.5 pounds.
