1 Introduction: The Humboldt HM-4187A De-Airing Tank is designed to remove dissolved gasses from ordinary tap water. The De-Airing tank requires a source for vacuum, tap water, and a 110 VAC electrical supply. The apparatus consists of a closed cylinder with a motor driven impeller. The rotation of the impeller causes the gasses to separate from the water while under a constant vacuum. The gasses are evacuated from the tank at the top.
