Maximum Capacity - 60 scfm / 102 Nm³/hr. Only the SEP60ST gives you this performance from such a small package. Our STERLING filter medium gives SEP 60 ST the capacity to out-perform separators 4 times its size, and it is pure simplicity to install and replace. Just fix the permanent back plate to a wall or cabinet, insert two push-in fittings and it starts to protect you and the environment. Oily water in, clean water out. Discharge straight to the sewer (as low as 5ppm oil-in-water) - legally* At the end of its service life, remove the push fittings, attach the clip-on lid and plug (provided with the replacement unit) and slide it off the wall plate. Sealed, outwardly clean and ready for disposal.
