4. Monitoring and Adjustment : Use the control panel to monitor the performance of the compressor and make necessary adjustments to maintain optimal working conditions.

Matching accessories

• Storage tanks : To increase the compressed air storage capacity and reduce the compressor on/off cycle.
• Air Dryers : To remove moisture from compressed air and prevent corrosion of tools and machinery.
• Filters and Separators : To keep compressed air clean and free of contaminating particles.

Mathematical Formulas for Optimal Use

• Compression Capacity:

  $$Q$$

  Where QQ $Q$ is the compression capacity, VV $V$ is the air volume, P1P1 $P$ $1$ is the inlet pressure, P2P2 $P$ $2$ is the outlet pressure, RR $R$ is the gas constant and TT $T$ is the temperature.

• Energy Consumption:

  $$E$$

  Where EE $E$ is the energy consumed, PP $P$ is the engine power, tt $t$ is the operating time and efficiency is the compressor performance.

Workable Materials

The Kaeser SK26 HP 20 compressor is specifically designed to process compressed air. It is not intended to work with solid or liquid materials, but is ideal for applications requiring a clean, continuous supply of compressed air.

Maintenance

• Oil Check : Check and replace compressor oil regularly to ensure adequate lubrication and prevent damage.
• Cleaning Filters : Filters must be cleaned or replaced to maintain compressor efficiency and ensure high quality compressed air.
• Cooling System Inspection : Check the cooling system to prevent overheating and ensure optimal operation.
• Periodic Check : Regularly check the electrical connections and control panel to ensure that the compressor is working properly.

Evaluation of Good Used

• Visual Condition : Examine the compressor for signs of wear or damage. A used compressor in good cosmetic condition is indicative of adequate maintenance.
• Operating Hours : Check the hours of use to evaluate the degree of wear. Fewer hours suggests limited use.
• Maintenance Documentation : Check whether maintenance documentation is available to confirm that the compressor has been well maintained.
