Landia AirJet aerators


An Air Jet consists of a Landia chopper pump and an ejector system. With its effective knife system, the chopper pump ensures that the aerator does not get clogged due to contaminants in the wastewater.


Application areas for Landia AirJet are typically

  • Aeration of waster water or sludge

  • Combined mixing and aerating

  • Eliminating odours from wasterwater - the wasterwater is kept fresh

  • Additional aeration during peak periods

  • Aeration of industrial wasterwater - often due to problems with other types of aerators

  • Cleaning/flushing of counter basins 


Benefits include the following

  • Can be mounted in a full tank

  • Clog-free - even with a high content of solids, such as in sludge

  • No maintenance of the aerator - only the pump needs to be serviced

  • Simultaneous aerating and mixing

  • Self-priming down to 19’ - no need for supply of compressed air

  • Low noise levels

  • The complete AirJet system can be supplied in stainless steel, including the pump
