All series of Air Sentry™ breathers can be filled with activated carbon for removal of fumes and airborne chemicals. This is extremely helpful in fuel and battery charging applications.
Air Sentry™ breathers are fitted with a standard 2-micron inlet and discharge filter. Air Sentry™ filters have an effective operating temperature range of -20°F (-29°C) to +200F (+93°C). Air Sentry™ breathers operating in temperatures ≥150⁰F (66⁰C) should have a protective barrier from the heat source.
