ATK series is designed to make your yard both beautiful and practical. Its unique feature—everything under one lid—integrates the air blower and smart controller inside the unit. These 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 without obstacles. The AT20K model is designed for treating domestic wastewater from two-family houses, apartment buildings, as well as recreational and commercial properties.
