Double oil filters, also known as duplex oil filters, are specialised filtration units designed for use in industrial refrigeration systems, particularly those employing ammonia (NH₃) or CO₂. They continuously eliminate impurities from the compressor oil while ensuring uninterrupted operation during filter maintenance or replacement.

A double oil filter features two parallel filter housings linked by a changeover valve or a three-way valve. This innovative setup enables the system to alternate between filters without the need to shut down the refrigeration system, ensuring optimal efficiency.
