A discharge head is connected to a double pump for air and liquid. The air and liquid are separately passed by pump actuation through a flow calming member and then into a combining member in a way such that the air enters in the form of numerous individual jets and under a low pressure and at a low flow rate into a liquid-wetted screen unit provided in a widened chamber. In the vicinity of the screen unit which are supplied with liquid from a chamber, the liquid can be foamed in a stepwise manner with the aid of air until the foam is discharged ready for use through an end channel.
