STEAMAX PRIV M17 – NOTES & PRECAUTIONS
Sub-ohm vaping (direct lung inhalation)
While puffing, the vapor of an e-cigarette is directly inhaled into the lungs. This puffing technique is referred to
as sub-ohm vaping with direct lung inhalation. To achieve this, there must be low puffing resistance and a strong
air supply to the evaporator head. Both have a positive effect on producing large quantities of vapor. Evaporator
heads that support this puffing technique in the sub-ohm range (resistance usually < 1 ohm) are often referred to
as DL (direct lung) heads. (Other abbreviations include DTL and D2L)
