TRANE AMERICAN STANDARD OXBOX Horizontal Drain Pan PAN03983

The PAN03983 is a genuine OEM horizontal drain pan (also referred to as a condensate pan or drip pan) designed for Trane, American Standard, and Oxbox air handlers and HVAC systems. Measuring approximately 21.33″ x 13.42″ x 1.18″ (with some listings noting compatible dimensions like 21-1/3″ x 12″ x 6-1/2″ depending on configuration), this durable plastic pan efficiently collects and directs condensation away from the evaporator coil.

Key Features

  • Durable Corrosion-Resistant Construction: Made from high-quality, corrosion-resistant plastic that withstands constant moisture exposure and prevents rust or degradation common in metal pans.
  • Precise OEM Fit: Direct replacement for compatible Trane/American Standard air handler models; ensures perfect compatibility and easy installation.
  • Horizontal Orientation: Optimized for horizontal airflow configurations in air handlers.
  • Efficient Condensate Management: Features proper sloping and drainage design to channel water quickly to the condensate line, reducing overflow risk.
  • Lightweight & Compact: Easier to handle during installation or replacement compared to heavier alternatives.

Benefits

  • Prevents Water Damage & Mold: Effectively collects condensation from the cooling coil, directing it safely away to avoid leaks, ceiling damage, or microbial growth.
  • Reliable Long-Term Performance: High-quality materials extend the life of your HVAC system and reduce the frequency of costly repairs.
  • Improved System Efficiency: Proper drainage helps maintain optimal humidity control and prevents issues like frozen coils or reduced airflow caused by overflow or blockages.
  • Peace of Mind: As an OEM part, it meets manufacturer standards for safety, fit, and performance, helping you avoid warranty concerns with aftermarket substitutes.

This PAN03983 drain pan is an essential component for maintaining a healthy, efficient, and leak-free HVAC system. Ideal for homeowners, HVAC technicians, and contractors looking for a reliable OEM replacement.

Note: Always verify compatibility with your specific air handler model before purchase. Professional installation is recommended for optimal performance.
