Carrier 50DK506358 Exhaust Regulator

Maintaining precise static pressure and flue terminal velocity is critical for the long-term reliability of commercial package units. The Carrier 50DK506358 Exhaust Regulator is an essential OEM replacement part designed to manage airflow within the exhaust assembly of high-efficiency gas-fired systems. Utilizing a 2-hole mount configuration, this regulator ensures that exhaust gas velocity remains within factory parameters, preventing common field issues such as flame rollout, pressure switch trips, and improper combustion. Built with industrial-grade materials, the 50DK506358 provides the structural integrity needed to withstand high-temperature flue environments in demanding HVACR applications. This component is specifically engineered for compatibility with various Carrier 48HCDA and 48TCDA series models, serving as a direct fit for the CRR50DK506358 specification. Integrating this genuine Carrier part during preventative maintenance or repairs ensures your unit maintains its original ASHRAE efficiency ratings while securing the integrity of the heat exchanger through consistent ventilation control.

• Precise Airflow Regulation: Optimizes flue gas discharge to prevent backpressure and ensure stable burner operation.
• OEM Compatibility: Designed specifically for Carrier commercial package units, ensuring a perfect 2-hole mount fit without field modification.
• Enhanced System Safety: Mitigates the risk of carbon monoxide buildup and heat exchanger fatigue by maintaining proper draft.
• Durable Construction: Engineered to resist the corrosive effects of combustion byproducts and thermal cycling.

What are the symptoms of a failing HVAC exhaust regulator?
Technicians typically observe intermittent pressure switch faults, evidence of flame rollout, or excessive soot accumulation in the flue collector box when the regulator fails to maintain the correct venturi effect.

Is the 50DK506358 compatible with other brands?
While functionally similar to other exhaust airflow regulators, this part is a genuine Carrier OEM component designed for specific tolerances in Carrier, Bryant, and Payne rooftop units. Always verify the model and serial number for exact fitment.

Why is the 2-hole mounting pattern significant?
The dual-hole configuration ensures precise alignment with the blower housing, preventing bypass air leakage that can disrupt the combustion air prover signals.
