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 va
-
ping 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)
