The volcano vaporization system is probably one of the best vaporizers available on the market! The patented cone heating guarantees an absolutely even evaporation of the herbs! It is also very practical that the steam is fed into a balloon and stays fresh there for several hours. which allows for a slower and therefore more effective absorption of the inhalat. The volcano is available either as a classic with a stepless regulation of the hot-flow or as a digital version that allows for a degree of accurate vaporization. The hot air generator is supplied with either a solid valve or an easy valve. We recommend the solid valve since this is more robust and the balloon itself can be changed, which allows to determine the size of the balloon itself! The easy valve is useful if several people want to have their own balloon at the same time.
