What it looks like visually
The Kaeser AS 31 compressor has a compact, industrial design, typically painted in Kaeser's signature yellow and gray. The air receiver and dryer are integrated into a single system to reduce space requirements 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 operate the Kaeser AS 31, connect the compressor to a three-phase power supply (380-400 V) and a compressed air distribution network. The integrated dryer activates automatically to ensure moisture-free air.
Matching accessories
- Air filters : To further improve the quality of your compressed air.
- Remote monitoring systems : To check the compressor status 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 rate
Maintenance
- Filters : Clean or replace air and oil filters regularly.
- Dryer : Check operation periodically 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 cared for regularly.
- Visual Condition : Inspect for any signs of wear or corrosion.
Sectors of Use
- Manufacturing Industry : Power supply of pneumatic equipment.
- Automotive sector : Painting and tire 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 cost 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 a long lifespan, if properly maintained.
