Armstrong 3LD Liquid Drainer, 1" NPT, 5/32 Orifice

The Armstrong 3LD Liquid Drainer is a robust, cast iron device designed for efficiently removing liquids from compressed air and gas systems, preventing damage to equipment and ensuring optimal performance. This model features a free-floating lever mechanism with an inverted bucket design, providing reliable drainage of condensate, oil, and other liquids without significant loss of air or gas. Key applications include compressed air lines, aftercoolers, separators, and drip legs in industrial settings such as manufacturing, petrochemical, and food processing plants. Advantages include high durability in harsh environments, resistance to water hammer, and a maximum operating pressure of 250 PSI, outperforming many thermoplastic alternatives in high-pressure scenarios. However, its cast iron construction may add weight and require periodic maintenance to prevent corrosion, especially in moist conditions. This unit offers excellent capacity for its size, with a 5/32" orifice allowing efficient flow rates up to several hundred pounds per hour depending on differential pressure. Compared to similar products like those from Spirax Sarco, the Armstrong 3LD provides superior longevity and ease of servicing, though it may have a higher initial cost. Overall, it's a dependable choice for reliable liquid drainage with minimal downtime.
