The AIR-2 from C.A.P. has the same features as the AIR-1 with the addition of separate temperature and humidity outlets. This allows you to control the temperature and humidity independently. Once you connect your temperature controlling device (air conditioner, fan, etc.) and a dehumidifier to the AIR-2, your temperature and humidity are automatically maintained. The AIR-2 is rated for 15 amps @ 120 volts. 3 year no hassle warranty.
