A natural gas compressor is a mechanical device that compresses natural gas to a high-pressure state to meet the needs of storage, transportation, or end-use.

Residential natural gas compressors, as a subcategory, primarily serve small-scale gas supply scenarios, such as providing a stable gas supply for detached houses, restaurants, or laboratories. Their core function is to mechanically reduce the volume of gas while maintaining stable pressure, ensuring the normal operation of gas-using equipment.
