Dynavap The Unidyn

Air enters the UniDyn through the perforated top of the BallR cap and passes over its stainless steel balls before it reaches the herb, so the media sits upstream of the vapour and stays comparatively clean. The residue lands below it: in the titanium bowl, on the stainless CCD screen and along the condenser tube.

1. Three pieces, not four. Pull the BallR cap off, then slide the condenser assembly out of the stem. That is the entire teardown. The tip and stem are a single titanium piece on this model, so there is no joint to separate and nothing to realign afterwards.

2. Roll both o-rings off. The UniDyn carries only two high temp o-rings and both sit on the condenser, because the unibody design removes any need for them at the tip. Take them off before alcohol touches anything, since DynaVap warns that isopropyl dries silicone out.

3. Soak the titanium. The unibody and the bare condenser go into 90% or stronger isopropyl for fifteen to thirty minutes, or hot water with dish soap. All metal DynaVap parts are dishwasher safe. The cap is the exception.

4. Swab the cap, never soak it. Moisture trapped in the crimped end around the bimetallic disc ruins the cap the next time you heat it. DynaVap asks for soapy water on a cotton swab rather than alcohol, which is flammable near a torch, and 24 hours of drying if the cap ever does get wet. Torch soot on the outside lifts with metal polish or a baking soda and vinegar paste, but keep abrasives away from the DuraDyn finish on the body.

5. Leave the balls where they are. The 3mm stainless media stays in place for routine cleaning. The cap does come apart if you want to swap in DynaVap's 2mm stainless or green sapphire Core Balls, and DynaVap demonstrates the process itself, but opening it at every wash only risks scattering them.

6. Screen, then condenser. Push the CCD out from the stem end with the condenser tube, soak it, then press it back in low for the full 0.1g bowl or high for the half bowl. The upper position can be stubborn to seat. Run a pipe cleaner through the condenser and wipe the outside of its shaft, since that surface is what the seven airflow positions grip.

Wet the o-rings with water or DynaWax before refitting. Brush the bowl out after each session and strip the device fully every week or two.
