This wall-mounted stainless steel wall box houses a copper drain line that extends through the wall box outlet to a sand/oil drain main below. The vent line ties into the main vent extending through the assembly. The drain line is sized according to the maximum flow rate of discharge, and the trap depth maintains one inch deeper than the static pressure. The drain receptor connection mirrors compressed air configurations and mounts securely to the wall.
