What it looks like visually
The Kaeser AS 31 compressor has a compact and industrial design, usually painted yellow and grey, Kaeser's signature colours. The tank and dryer are integrated into a single system to reduce clutter and improve efficiency.
Mechanical Characteristics
- Motor speed : Adjustable via an inverter to optimize energy consumption.
- Operating temperature : The compressor is designed to operate at variable ambient temperatures, maintaining an optimal internal temperature thanks to the cooling system.
Use and Operation Procedure
To use the Kaeser AS 31, connect the compressor to the three-phase electrical network (380-400 V) and to the compressed air distribution network. The integrated dryer activates automatically to ensure moisture-free air.
Matching accessories
- Air filters : To further improve the quality of compressed air.
- Remote monitoring systems : To check the status of the compressor and optimize maintenance.
Mathematical Formulas for Optimal Parameters
- Flow rate (m³/min) = Tank volume (litres) ÷ Compression time (minutes)
- Energy efficiency : kW/h consumed = (Motor power × Operating hours) ÷ Air flow
Maintenance
- Filters : Clean or replace air and oil filters regularly.
- Dryer : Periodically check operation and replace worn components.
- Checking the tank : Make sure there are no leaks and that the safety valve is working properly.
How to Evaluate a Good Used Compressor
- Operating hours : Check the operating hours counter.
- Previous maintenance : Check the maintenance log to see if the machine has been serviced regularly.
- Visual condition : Inspect for signs of wear or corrosion.
Sectors of Use
- Manufacturing industry : Powering pneumatic equipment.
- Automotive sector : Tire painting and inflation.
- Chemical and pharmaceutical industry : Impurity-free compressed air for production processes.
Why It's Better to Buy Used
A used compressor like the Kaeser AS 31 offers significant economic savings compared to a new one, while maintaining high performance standards. Thanks to its robustness and efficient design, even a used model guarantees reliability and long life, if well maintained.
