L-Series - In-Line Low Airflow

guardian air breather featuresair sentry brochure

Air Sentry® In-Line Filter / Dryers 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.

The L-Series breathers are available with 100% silica gel or activated carbon, or a combination of both, as necessary. (Carbon filters are special order - please call for more information)

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. The L-Series is rated up to 60 psi and mounted on the regulated side of the air line. This series offers these benefits:

  • Minimize rust and corrosion
  • Reduce component wear
  • Reduce maintenance costs
  • Prolong fluid life
  • Reduce oil oxidation
  • Eliminate fumes and odors
