These breathers include an in-line filter/dryers that remove water vapor and solid contaminants from air exhaust lines, low pressure compressed air lines, vacuum lines, and other in-line airflow applications where clean, dry air is required. Air enters the filter/dryer in one end and is clean and dry when leaving the other end. Water vapor and solid particles down to 2 micron are removed. L-Series is rated up to 60 psi and mounted on the regulated side of the air line.

All L-Series models feature two 2 micron filters, one on the inlet and a second on the outlet.
