The Vaporbrothers model is considered a convection type with passive airflow, which means it uses hot air instead of any direct metal contact with the herbs, and does not generate any fan noise. As soon as the user fills the glass Whip Handpiece and joins it to the heating element, the vaporizer is ready to use.
By inhaling through the tube, air is drawn through the vaporizer's heating chamber and into the herbs. A warm flow of air saturates the herbs, heating them to about 163 °C. At this temperature, the plant matter does not burn, but the oils and moisture contained within the plant are released into the air and become cool again. This becomes a clear vapor mist which travels up the tube to the user. When the vaporizer is used properly, the inhaled vapor is clear, and exhales as a visible white mist.
This vaporizer works with essential oils as well. Simply attach the supplied Aromabulb™ oil diffuser to the heating element, fill it with filtered water and a few drops of essential oil, and turn the vaporizer to its lowest setting. The vaporizer's heater will gently warm the oil until it evaporates into the room.
