Air Sentry D series

D-Series Breathers | Reliable Moisture & Fume Control for Fluid Management

The D-Series breathers offer a variety of models in different sizes, designed to meet the needs of stationary fluid management applications. Featuring 100% silica gel for moisture adsorption, 100% activated carbon for fume and odour control, or both, these breathers include 2-micron filtration and airflow ratings of 20 cfm. Constructed with industrial-grade materials, they feature high-impact ABS caps and a clear acrylic tube for easy inspection of the silica gel's condition. The gel changes colour from gold to dark green, visually indicating moisture absorption and confirming the breather's performance. All materials are tested for chemical compatibility with industrial lubricants, fuels, and fluids.
