The innovative StarBox² series for air/oil separation in compressors shines with maximum performance in the area of volume flow and minimum pressure loss. It not only reliably separates compressor oil from the compressed air, it also does so with minimum energy consumption. Compared to other spin-on separators, the StarBox² impresses with up to 25 percent less pressure loss.
