The ATK series is designed to make your yard not only beautiful but also practical. Its unique feature—everything under one lid—integrates the air blower and smart controller inside the unit. The units are installed at ground level, ensuring they do not interfere with landscape maintenance. This design allows for easy mowing with both traditional lawnmowers and robotic mowers, as there are no obstacles to worry about. The AT15K model is designed for treating domestic wastewater from a two-family or duplex house.
