The invention relates to a hot dip coating device (100) for coating a met al strip with molten metal (200) and to a method for operating said device. The metal strip is deviated in the molten metal (200) by means of a roller ( 120). Said roller is rotatably received in a bearing (144) in a supporting a rm (105). The bearing is mounted in a bearing compartment (142). In order to seal the bearing compartment (142) from the undesired entry of molten metal (200), a sluice is arranged between the bearing compartment (142) and a rol ler passage (136) to the molten metal (200) and is impinged upon by a gaseou s medium at gas pressure to seal the sluice chamber (132) from the molten me tal (200). The aim of the invention is to reduce the maintenance work requir ed for said sluice. To achieve this, the sluice chamber (132) is configured in the shape of a diving bell having a channel-type exit (134) which is open to the surrounding molten metal (200).
