The right air compressor depends on your packaging application, required air quality, pressure, air flow and operating conditions. Sollant provides oil-free water-lubricated screw compressors, permanent magnet variable speed screw compressors, 3-in-1 integrated compressor systems, refrigerated air dryers and precision filters for different packaging applications.

For food and pharmaceutical packaging applications where clean compressed air is critical, an oil-free compressor solution may be appropriate. For packaging machinery requiring stable pneumatic power, a variable speed screw compressor can be configured according to the actual air demand.

For packaging applications where compressed air can come into direct or indirect contact with food, packaging materials or the production environment, compressed air quality is an important consideration.

Sollant’s SLTOF-45VW oil-free water-lubricated screw air compressor is designed for applications requiring oil-free compressed air and is available in 8, 10 and 12.5 bar configurations.

The required air quality should be determined according to the specific application, applicable industry standards and your customer’s quality requirements.

Class 0 refers to the highest air purity classification for oil content under ISO 8573-1. It is used where the risk of oil contamination needs to be minimized, such as certain food, pharmaceutical and other sensitive manufacturing applications.

If your packaging process requires Class 0 compressed air, we recommend selecting a compressor and complete air treatment system based on the required air quality, operating conditions and applicable certification or test requirements.

The required pressure depends on the specific packaging machine and pneumatic components. Different applications may require different pressure levels.

Sollant offers packaging air compressor solutions with pressure configurations including 7, 8, 10, 12.5 and 13 bar, depending on the selected model.

When selecting a compressor, we recommend checking the required working pressure of your packaging equipment and allowing for appropriate pressure loss throughout the compressed air system.

Compressor capacity should be selected based on the actual compressed air consumption of your packaging equipment rather than motor power alone.

The main factors include:

• Required air flow
• Working pressure
• Number of machines operating simultaneously
• Peak air consumption
• Operating hours
• Future production capacity
• Air quality requirements

You can send us your required pressure, air consumption and packaging application. Our engineers can recommend a suitable compressor configuration based on your operating conditions.

A variable speed drive (VSD) screw compressor can be suitable for packaging lines where compressed air demand changes during production.

The SLT-30V permanent magnet variable speed screw air compressor is available in 30 kW configurations, with 8, 10 and 13 bar pressure options and an air flow range of 1.03–3.60 m³/min.

By adjusting compressor output according to air demand, a VSD system can help improve operating efficiency compared with a fixed-speed compressor in applications with significant fluctuations in air consumption.

In many compressed air systems, air treatment is required to control moisture and protect downstream pneumatic equipment.

Compressed air naturally contains water vapor. When compressed air cools, moisture can condense and enter the air distribution system.

Sollant offers refrigerated air dryers with pressure dew points of approximately 2–10°C, depending on the model and operating conditions. The appropriate dryer should be selected according to your required pressure, air flow, inlet conditions and required dew point.

Precision filters can help remove particles, oil aerosols and other contaminants from compressed air, depending on the filter grade and operating conditions.

For packaging applications with specific compressed air cleanliness requirements, the compressor should be considered together with the dryer, filters, piping and end-use equipment as a complete compressed air system.

Sollant can provide refrigerated dryers and C/T grade precision filtration solutions for packaging applications.
