The HMD smokebox attachment: The tool for perfect heat regulation

The HMD or Smokebox attachment is a product from the USA and was brought onto the market as an extension of the Apple on Top, which works on almost the same principle. The HMD Smokebox attachment is a dome made of a special aluminum alloy, making it particularly corrosion-resistant.

The HMD smokebox attachment: This is how it is constructed

On the underside there are knobs in a ring-shaped formation. The whole thing is rounded off with a lid that has a handle with which the air inlets can be opened and closed. At the lower edge of the body and on the underbody there are also elongated air slits in a ring formation. On the side of the HMD smokebox body, the air inlets serve as an opening for fresh oxygen to the underside of the coal so that it cannot run out. The air inlets on the bottom are the passage for the warmed air from the interior of the HMD attachment and serve as a route for the warm air flow. This ensures the function of the construction. Because the air flow has to find exactly this path from the outside to the inside of the phunnel hole. The lid has two sliding elements that lie flush with each other and are connected to each other by a screw.

Which tobacco bowls is the HMD smokebox attachment compatible with?

The HMD works best in conjunction with a phunnel because it brings out its full potential: the coal heats the aluminum body and the side openings in turn serve to let in fresh oxygen-rich air for the glowing coals . The heated air pushes out through the side slots in the base and, together with the heated knobs on the underside, transfers the tobacco . The liquid in the tobacco evaporates and flows into the shisha through the phunnel hole. The whole thing works with a different bowl, but the smoking time is shortened because the molasses leaves the depot more quickly and the tobacco dries and burns more quickly.
