Sporlan 470069 Accumulator

The Parker Sporlan 470069 (Model VPA5811-7SRD) is a high-capacity suction line accumulator engineered to protect compressors from liquid floodback and oil slugging in high-demand refrigeration and air conditioning systems. Designed with a robust 5-inch diameter steel shell, this 7/8" ODF unit features a specialized U-tube design that ensures maximum refrigerant flow with a minimal pressure drop. An integrated inlet flow deflector directs incoming refrigerant toward the vessel wall, facilitating smooth expansion and preventing liquid from entering the compressor intake. This accumulator is optimized for both R-22 and R-410A applications, with a maximum working pressure rating of 355 psig (with some configurations tested up to 680 PSI). For field reliability, it includes a 430°F safety fuse plug and a protective screen on the metering orifice to prevent debris from compromising oil return. This is a critical HVAC system protection component for heat pumps and low-temperature systems where varied operating conditions frequently lead to liquid surges.

• Compressor Protection: Prevents liquid slugging and ensures only vapor reaches the suction valves to prevent mechanical failure.
• Efficient Oil Return: Features a calibrated metering orifice and protective screen to maintain proper crankcase lubrication without excessive refrigerant dilution.
• High-Flow U-Tube: Designed for minimal pressure drop, maintaining system capacity even during peak load conditions.
• Durable Construction: Steel body with solid copper 7/8" ODF connections for secure, leak-free brazing.
• Integrated Safety: Includes a factory-installed fuse plug to protect the vessel against extreme thermal over-pressurization.

What is the holding capacity for R-410A vs R-22?
The VPA5811-7SRD has a holding capacity of approximately 102 oz. for R-410A and 112 oz. for R-22 at standard suction temperatures.

Can this accumulator be used on heat pump systems?
Yes, this model is specifically suited for heat pumps and systems with hot gas defrost where sudden liquid returns are common during cycle changes.

What is the correct mounting orientation?
This is a vertical accumulator and must be mounted upright as close to the compressor as possible to ensure the siphoning action of the U-tube functions correctly.
