• Energy Efficiency : The inverter allows the compressor to adapt the motor speed to the actual load, reducing energy consumption and improving efficiency.
• Quiet : The design and high-quality materials reduce operating noise, making the compressor suitable even for noise-sensitive environments.

Usage Procedure

1. Installation : Place the compressor on a flat and stable surface, making sure you have sufficient space for ventilation. Connect the compressor to the three-phase electrical network.
2. Electrical Connection : Connect the compressor to the electrical system, following the manufacturer's specifications. Make sure connections are secure and comply with safety regulations.
3. Switching on : Start the compressor using the control panel. The inverter will automatically adjust the motor speed based on the demand for compressed air.
4. Adjustment and Monitoring : Use the control panel to monitor and adjust pressure and airflow settings. The inverter will allow you to optimize energy consumption.

Matching accessories

• Filters and Separators : To ensure high quality compressed air, it is advisable to use filters and oil separators.
• Accumulation tanks : Increase the accumulation capacity and stabilize the air flow.
• Air Dryers : To remove humidity and improve the quality of compressed air.

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 7.5 kW Inverter compressor is designed to process compressed air. It is not suitable for treating solid or liquid materials. It is ideal for applications requiring a continuous and reliable flow of compressed air.

Maintenance

• Oil Check : Check and replace oil regularly to ensure adequate lubrication.
• Cleaning the Filters : Clean or replace the filters to maintain the quality of the compressed air.
• Cooling System Inspection : Check the operation of the fan and cooling system to avoid overheating.
• Periodic Check : Monitor the electrical connections and control panel to ensure correct operation.

Evaluation of Good Used

• Visual Condition : Examine the compressor for signs of wear or damage. A good used compressor should be in good cosmetic and operational condition.
• Operating Hours : Check the hours of use via the counter. Fewer hours indicates less wear.
• Maintenance Documentation : Request maintenance documentation to confirm that the compressor has been regularly checked and repaired if necessary.

Sectors of Use
