The Danfoss 040B0010 is a 3/4″ flare OUB-series oil separator engineered to protect refrigeration and HVAC systems by capturing and returning compressor oil back to the compressor crankcase. By preventing oil from circulating through the refrigerant circuit, this separator helps maintain peak system efficiency, protects compressor longevity, and reduces the risk of oil logging in evaporators and other downstream components.
Key Features
- 3/4″ flare connections for straightforward field installation
- OUB-series design optimized for reliable oil separation in refrigeration systems
- Helps protect compressor by continuously returning separated oil to the crankcase
- Reduces oil circulation through the refrigerant circuit, maintaining heat transfer efficiency
- Durable construction built to Danfoss quality standards for long service life
- Compatible with a wide range of common refrigerants used in commercial and residential HVAC/R applications
Why Use an Oil Separator?
Oil separators are a critical component in refrigeration systems where compressor oil must be kept out of the refrigerant circuit. Without proper oil return, oil can accumulate in evaporators and other heat exchangers, reducing system efficiency and potentially starving the compressor of lubrication. The Danfoss 040B0010 addresses this challenge with a proven separation design that keeps your system running at its best.
