Mepco (Dunham Bush) D2488 Trap

The Mepco (Dunham Bush) D2488 Trap is a 3/4-inch thermostatic steam trap designed for precision condensate management in low-pressure steam heating systems. Specifically engineered with a 2E-AP angle pattern, this trap is a direct, identical replacement for the 2E-AP radiator trap. It features a rugged brass body and a thermostatic bellows element that maintains high sensitivity, ensuring effective air and non-condensable gas removal while preventing live steam from short-circuiting into the condensate return line. Rated for a maximum operating pressure of 25 PSI, this unit facilitates a high condensate capacity of approximately 2,450 lbs/hr, making it a reliable choice for commercial and industrial HVAC system integrity. The union inlet and NPT connections provide a straightforward fit for standard 3/4" piping configurations. Whether you are performing a steam trap repair or a full system overhaul, the D2488 provides the thermal responsiveness required to optimize radiator performance and system drainage.

• Angle Pattern Configuration: Designed for standard radiator connections with a 3/4" NPT inlet and outlet for simplified installation.
• High Condensate Capacity: Supports efficient drainage with a capacity of up to 2,450 lbs/hr at maximum operating differential.
• Optimized Steam Retention: The thermostatic element precisely distinguishes between condensate and live steam to minimize energy loss.
• Durable Construction: Heavy-duty brass body and stainless steel disc internals withstand the corrosive environments of steam returns.
• Direct Interchangeability: Fully compatible with existing Dunham Bush 2E-AP footprints, requiring no piping modifications.

Is the D2488 compatible with older 2E-AP models?
Yes, the D2488 is identical to 2E-AP units. It shares the same dimensions, capacity, and 3/4" angle pattern, making it a drop-in replacement for legacy Dunham Bush installations.

What is the maximum pressure rating for this trap?
This thermostatic radiator trap is designed for low-pressure applications with a maximum operating pressure of 25 PSI, covering the standard range for most commercial steam heating systems.

Does this unit include a strainer?
No, this specific model is the trap assembly only. For improved steam trap performance and to protect the bellows from debris, it is recommended to ensure the system line is clear or utilizes an external strainer if required by the application.
