OTA/OTB Series
The OTA/OTB series was Westfalia's standard marine separator of the 1970s and 1980s. OTA models had manual discharge, OTB models semi-automatic. Widely distributed on German vessels of that era. Replaced by the OSD series and later the OSC series. Still sporadically in operation on old bulkers and coastal vessels, but spare parts supply practically only through the second-hand market.
