Are air compressors used in the pharmaceutical industry slightly or oil-free?

In the pharmaceutical industry, the cleanliness of compressed air is directly related to the quality of drug production and process compliance. Since drug production requires extremely strict pollution control, any oil residue may affect product purity or cause equipment failure, industry regulations usually require the use of oil-free compressed air.

Limitations of micro-oil air compressors
Traditional micro-oil air compressors use lubricating oil to achieve component lubrication and sealing. Although multi-stage filtration is used, there may still be a risk that trace oil will spread with the air flow. In core pharmaceutical processes (such as aseptic filling and liquid mixing), such residues may contaminate products or damage precision instruments.

The core advantages of oil-free air compressors
Oil-free technology replaces oil lubrication through physical design (such as water lubrication, ceramic sealing) to prevent oil from entering the gas path from the root cause. Granklin’s water-lubricated single-screw air compressor uses water as the lubricating medium. Combined with the compact structure of the single screw and star wheel, it completely avoids the participation of lubricating oil during the compression process, ensuring that the output compressed air is free of oil pollution, and is highly compatible with the pharmaceutical industry. Strict requirements for air source cleanliness.

Industry application scenario adaptation
In key aspects such as preparation sub-packaging, process cleaning, and automatic control, oil-free compressed air can ensure stable equipment operation and product sterility standards. Granklin air compressors provide pharmaceutical companies with power solutions that meet GMP regulations through oil-free design and stable air supply capabilities.
