The Direct Air Tube for the Revolve Stem by MAD Heaters allows for three airflow options in addition to the three options provided by the included DRC Tube.
Direct Air Tube Airflow Options
|Direct Open - Vapour passes straight down the centre of the stem while cold air is brought in through the port, direct to the mouthpiece.
|Direct Bypass - While vapour is being drawn straight down the centre of the stem, cold air is drawn in through the intake port where it travels up around the helix, providing a little cooling to the vapour inside the centre, before mixing with the vapour and travelling down the centre of the stem to the mouthpiece.
Direct Closed - The airport is closed, vapour is drawn down the centre of the stem like a regular DynaVap for that toasty vapour..
- 1 x Direct Air Tube in Black, Silver or Rainbow
- Installed o-ring
Due to the finishing process, each Rainbow Airflow Tube is unique and vary in colour.
Always a pleasure doing business with this company, and the direct air flow is just another piece to add, does exactly what it’s supposed too.
