For food and beverage applications, the appropriate compressor depends on the required air purity, pressure, flow rate and application. For processes where compressed air may come into contact with food, beverages or packaging, an oil-free Class 0 compressor can be considered to minimize the risk of compressor-generated oil contamination.

Sollant offers oil-free screw and scroll compressors for different food and beverage applications.

Compressed air may be used in filling, packaging, conveying, bottle blowing and other production processes. If air can contact the product or packaging, compressor-generated oil contamination can be a concern.

Oil-free compression helps minimize this risk and can be combined with appropriate air dryers and precision filters to meet the required compressed air quality.

Class 0 is the highest classification for oil contamination under ISO 8573-1. It is used for applications requiring particularly stringent control of oil contamination.

The required compressed air quality should always be determined according to the specific production process, air-contact conditions and applicable standards or specifications.

In most compressed air systems, moisture management is important because compressed air contains water vapor. The appropriate dryer depends on the required pressure dew point and operating conditions.

Sollant provides refrigerated air dryers and desiccant air dryers for different compressed air applications.

There is no single pressure dew point requirement for every food and beverage application. It depends on the production process, operating environment and compressed air specification.

Sollant can provide refrigerated or desiccant drying solutions with different pressure dew point requirements, including applications requiring -20°C to -40°C or lower.

Filtration requirements depend on the required compressed air quality and application. A complete system may use multiple stages of filtration to control particles, oil aerosols and other contaminants.

Sollant can configure precision filtration together with the compressor and dryer according to your application requirements.

The SLTOF-55FD variable frequency oil-free screw compressor is designed for applications such as packaging and pneumatic conveying where air demand may vary during production.

It provides Class 0 oil-free compressed air and is available in 7, 8 and 10 bar configurations.

The SLTOF-7.5S oil-free scroll air compressor is a compact, low-noise solution for applications requiring clean and stable compressed air.

It provides an air delivery of 1.2 m³/min at 0.8 / 1.0 MPa, making it suitable for applications such as filling and bottle blowing where its capacity and pressure match the production requirements.
