Carrier 343314-75104 Drain Pan

The Carrier 343314-75104 Horizontal Drain Pan is the direct engineering successor and OEM replacement for the discontinued 342023-706 and 321894-404 models. Designed specifically for Carrier, Bryant, and Payne horizontal air handlers and cased coils, this high-grade condensate management component ensures effective moisture evacuation to prevent secondary water damage. Constructed from corrosion-resistant galvanized steel with a black protective finish, this pan is built to withstand the rigorous thermal cycling of HVAC residential and commercial systems. The assembly features a precise 3/4" NPT drain connection and standard 31-1/4" x 22-1/2" dimensions for a drop-in fit. As a critical secondary drain pan alternative for multi-position applications, it maintains the structural integrity and airflow clearance required by factory specifications. This genuine factory-authorized part is essential for technicians performing corrective maintenance on leaking or cracked legacy pans in horizontal-flow configurations.

• Direct OEM Compatibility: Serves as the factory-validated replacement for 342023-706, ensuring identical mounting points and drainage slope.
• Heavy-Duty Construction: Fabricated from durable, corrosion-resistant metal to eliminate the risk of cracking common in plastic aftermarket alternatives.
• Optimized Condensate Flow: Features a single 3/4" outlet designed to maximize drainage velocity and minimize sediment buildup.
• System Protection: Engineered to integrate seamlessly with Carrier evaporator coils, preventing overflow and protecting furnace electronics or building interiors.
