Convection (heat flow) occurs when a stream of hot air heats the plant material in the vaporizer, producing vapor containing aroma and active ingredients.

The air heats up to the temperature preset by the user during convection. A blower transports the air through an herbal chamber into the oral tube or a balloon provided for this purpose.

This heating type (using warm air flow) achieves the following results:

  • herbs are heated evenly
  • high yield of active ingredient
  • no burning of the plant material

In theory, the vaporizing process combines two properties – convection and conduction. The hot air flow also heats the herb chamber, or a hot draft is created due to the heated chamber. Currently, the number of vaporizers that work with evaporation via convection dominates.
