Carrier 343470-75101 Drain Pan

The Carrier 343470-75101 Condensate Drain Pan is a critical OEM replacement part designed for residential and commercial HVAC condensate management. This 22.5" x 18" x 5" pan is the direct replacement for 328140-751 and is engineered specifically for Carrier, Bryant, and Payne air handlers and furnace coils. Built from a corrosion-resistant material, it provides a 3/4" primary drain connection to ensure efficient moisture removal and protect the surrounding equipment from water damage. This unit is optimized for horizontal drain pan configurations, allowing for a multipoise furnace or cooling coil to be converted for horizontal left or right air supply applications. As a Factory Authorized Part, it maintains the structural integrity and low air leak ratings of the original system while providing a precise fit for evaporator coil assemblies. This high-performance HVAC drain pan ensures reliable drainage under high-static conditions and prevents the common overflow issues associated with cracked or degraded aftermarket pans.

• Direct OEM Compatibility: Specifically engineered to replace the 328140-751 in Carrier/Bryant/Payne systems, ensuring a drop-in fit without field modifications.
• Advanced Moisture Control: Designed with a 3/4-inch NPT drain connection and proper pitch to facilitate rapid condensate removal and prevent stagnant water.
• Durable Construction: Fabricated from corrosion-resistant heavy-duty materials that withstand the thermal cycling found in modern A-coil and slope coil applications.
• Multipoise Versatility: Supports both horizontal-left and horizontal-right cabinet orientations, making it a staple for attic and crawlspace installations.
• System Security: Prevents secondary damage to ceilings and structural components by effectively managing indoor coil condensation.

• Is this pan compatible with R-410A systems? Yes, this condensate drain pan is designed to perform alongside Puron R-410A evaporator coils in standard HVAC ventilation setups.
• Does it include the primary and auxiliary plugs? Standard OEM pan kits typically require the installer to transfer or provide plugs for unused ports to maintain the low air leak performance of the cabinet.
• Can this be used in downflow applications? While primarily used for horizontal installations, check your equipment's specific installation instructions for multipoise conversion requirements.
