Automatic Filters Inc.’s Tekleen® is a line of automatic backwash filters designed for use in the HVAC industry, especially in cooling tower applications. According to the company, the filters eliminate contamination caused by airborne dust, sand, pollen, algae, and pipe scales.

These contaminates circulate through heat exchangers, chillers, and compressors, making the cooling system pump harder, effectively lowering the efficiency of the system. The filters operate on line pressure alone. The self-cleaning process is triggered by a pressure differential and is accomplished in seconds without interrupting the main flow. The filters are all offered in stainless steel construction.
