ATB HSA aerators generate a particularly flat water jet which is distributed 360° around the aerator. The range of applications extends from pond systems to activated sludge systems, SBR and MBR systems: Air-cooled motor: no seals in contact with water = extremely long lifetime Direct drive: no gear = almost maintenance-free Wide power range: available from 0.75 kW to 110 kW High turbulence generation: high mixing capacity and particularly high alpha value Horizontal water jet: minimal aerosol generation Installation: floating = fast and simple Materials: stainless steel V2A or V4A
