Parker-Sporlan VA356S Suction Line Accumulator — 3/4″ ODF
The Parker-Sporlan VA356S (SKU 470093) is a suction line accumulator engineered to safeguard refrigeration and air conditioning compressors from the damaging effects of liquid refrigerant and oil slugging. Featuring 3/4″ ODF connections, this accumulator is well-suited for a wide range of residential and light commercial HVAC/R applications where reliable compressor protection is essential.
What Is a Suction Line Accumulator?
A suction line accumulator is installed in the suction line between the evaporator and the compressor. Its primary function is to collect and temporarily hold any excess liquid refrigerant or oil that may carry over from the evaporator, metering it back into the suction stream as a vapor. This prevents liquid slugging — one of the leading causes of compressor failure — and helps extend the operational life of the entire refrigeration system.
Key Features
- 3/4″ ODF suction and outlet connections for straightforward field installation
- Designed to prevent liquid refrigerant and oil slugging at the compressor
- Durable steel shell construction for long-lasting performance in demanding HVAC/R environments
- Metered oil return orifice ensures proper lubrication is continuously returned to the compressor
- Compatible with a broad range of common refrigerants used in residential and light commercial systems
- Compact design for easy integration into existing suction line configurations
Applications
- Residential and light commercial air conditioning systems
- Heat pump systems subject to liquid floodback during defrost cycles
- Refrigeration systems with variable or fluctuating load conditions
- Systems prone to liquid migration during off-cycle periods
- Compressor replacement installations where added protection is recommended
