Industrial D-102 Desiccant Breather Package

Air Sentry D-102 Desiccant Breather Package is a 1-inch slip‑fit desiccant breather from the Air Sentry D‑Series, designed to replace standard vent caps on stationary reservoirs such as hydraulic tanks and power transformers to remove moisture and particulates from incoming air. The unit measures 8 inches in height and 5 inches in diameter, with a 1-inch slip thread, and houses a silica gel desiccant bed with a water‑absorption capacity of 13.9 oz (411 ml); it provides up to 35 CFM of airflow, features a clear acrylic tube to monitor the color-changing silica gel, and uses ABS top and bottom caps plus a replaceable desiccant cartridge with a high-capacity filter. The assembly weighs about 3.6 lb (1.6 kg) and is rated for an operating range from -20°F to +200°F (-29°C to +93°C). Typical uses include stationary hydraulic reservoirs, gearboxes, and oil-filled equipment such as power transformers, where it helps protect lubricant quality by reducing moisture ingress and particulate contamination.
