摘要

The foam generating unit has a water inlet (3) and an inlet (4) for chemicals, both of which are connected to a mixing unit (5), from which they pass to a foam generator (7). The mixing unit is designed as a proportional dosing unit, so that the water pressure does not drop as the chemicals are mixed with it.
