The Spirax-Sarco 52589 is a high-performance 3/4" NPT FA-150 Liquid Drain Trap engineered for the continuous discharge of condensate and liquids from compressed air and gas systems. Built with a rugged cast iron body and high-grade stainless steel internals, this float-operated trap ensures a positive liquid seal to prevent the loss of air or gas during operation. It is specifically designed to handle a maximum operating pressure (PMO) of 150 psig at temperatures up to 200°F. The Spirax Sarco FA-150 series is favored by contractors for its reliable stainless steel float mechanism that responds instantly to load fluctuations, making it ideal for large receivers and air-line drainage where consistent performance is critical. For optimal reliability, this industrial drain trap features a parallel piping configuration and an integrated balance pipe connection (1/4" NPT) to prevent air binding. Its serviceable design allows for the inspection and replacement of the valve mechanism without removing the main body from the piping, significantly reducing downtime during routine maintenance. Whether you are managing condensate removal in a manufacturing plant or protecting downstream equipment from moisture carryover, the 52589 liquid drainer provides the durable, field-proven solution required for high-demand HVACR and industrial applications. Key Benefits Continuous Discharge: The float mechanism automatically adjusts to liquid flow rates, ensuring thorough and efficient system drainage. Corrosion Resistance: Equipped with all-stainless steel internals to withstand harsh condensate environments and prolong service life. Maintenance Accessibility: Fully field-serviceable internals can be replaced without disturbing the inlet or outlet pipe connections. High Capacity: Optimized for heavy condensate loads, supporting up to 11,000 lb/hr at peak operating pressure. Pressure Versatility: Rated for a maximum allowable pressure of 150 psig, suitable for a wide range of compressed air receivers. Common Questions Is a balance pipe necessary for this drain trap? Yes, connecting a balance line to the 1/4" NPT tapping is essential. It prevents air or gas from becoming trapped in the body, which would otherwise impede the flow of liquid into the trap. Can the FA-150 be used for fluids other than water? While designed for water (specific gravity 1.0), it can handle liquids with different specific gravities. However, the discharge capacity and maximum operating pressure must be adjusted based on the fluid's density; always verify the conversion factor for your specific application. How do I service the unit if it fails to drain? The most common cause of failure is debris fouling the valve seat or a damaged float. Because the 52589 is a serviceable drain trap, you can isolate the unit, remove the cover bolts, and access the entire valve mechanism for cleaning or replacement using a standard kit.
