Hi again PPN,
IDK about the safe air path...
As an after thought lets just post some pictures from the available documentation:
VaporNation Elevape Smart - Oven
Heated air comes from below the oven and goes through one's vegetal matter before it changes direction under the cap, on its way for the amovible mouthpiece.
VaporNation Elevape Smart - Feedback Loop
It seems to me radiative heat can be expected to kick in quickly, which migh lead to an interesting result.
What's not so clear is where the "fresh" air comes from, not to mention what it went through.
More exactly, is it only a single-purpose item we can see next to the heater coil or does it have more than just 1 function? I mean, it could be nothing more than a tall lense meant to capture the orange glow, or perhaps it's actually a hollow glass tube working both as a light-guide and a source of air.
In any case i find it hard not to notice the mounting bars (with screws) have no sealed joints around them... Without complementary details this still leaves me with 2 possible main scenarios.
Last but not least, on page 8 of the .PPT document there's a plastic bag containing:
1 Silicone O-Ring
2 Mouthpiece Metal Filters
3 Donut-shaped (concentric hole) Metal Filters
Now that's a bit strange since i don't recall anything about metal filter discs that got a hole punched in the center and much less the reason why these would be needed! Any ideas?
