From Smeaton Fluid Machinery
When you need clean, reliable compressed air for food processing, pharmaceuticals, or high-tech manufacturing, an oil-free screw compressor is often the first choice. Smeaton’s TF55-500 family delivers exactly that – a robust two-stage design that guarantees oil-free operation, high efficiency, and flexible installation options.
A two-stage screw compressor compresses the air in two consecutive chambers, which means lower outlet temperature, higher volumetric efficiency, and the ability to reach higher discharge pressures without a cooling interstage. Because the rotors run without oil lubrication, the output is 100% oil-free – critical for industries where contamination can compromise quality or safety.
