  • Separate Radial Cooling Fan : This fan is designed to keep the compressor at an optimal operating temperature, reducing noise and improving efficiency.
  • Oil Tank and Separation System : Includes a compressed air tank and a system to separate the oil from the compressed air, ensuring clean, dry air.

• Measurements and Specifications:

  • Engine Power : 7.5 kW (10 HP)
  • Flow rate : 970 liters per minute
  • Output Pressure : Up to 10 bar (145 psi)
  • Cooling Type : Separate radial cooling fan, designed to reduce noise and improve thermal efficiency.
  • Dimensions and Weight : The compressor is designed to be compact and easily integrated into small spaces. The exact dimensions may vary, but it is generally designed to optimize available space in a workshop or craft environment.

Mechanical Characteristics

• Compressor Type : Rotary screw compressor, known for its efficiency and ability to operate with minimal vibration and noise.
• Quiet : Thanks to the separate radial cooling fan, the compressor is particularly quiet, making it suitable for work environments where noise is a concern.
• Energy Efficiency : The compressor design is optimized to reduce energy consumption, offering good performance with low operating costs.

Usage Procedure

1. Installation : Place the compressor on a flat and stable surface. Make sure there is sufficient space around for ventilation and cooling.
2. Electrical Connection : Connect the compressor to the three-phase electrical network. Check that the connection is secure and complies with technical specifications.
3. Startup : Turn on the compressor using the control panel. The engine will start running and the cooling fan will kick in to maintain operating temperature.
4. Adjustment and Monitoring : Use the control panel to set and monitor the pressure and air flow. Make sure the compressor is operating within optimal specifications.

Matching accessories

• Filters and Separators : Filters to remove impurities from compressed air and oil separators to keep the air clean.
• Accumulation tanks : To increase the accumulation capacity and stabilize the air flow.
• Air Dryers : To remove moisture from compressed air and improve air quality.

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 Dari DSB 8 compressor is specifically designed to handle compressed air. It is not intended for the treatment of solid or liquid materials. It is ideal for applications requiring a continuous and reliable flow of compressed air.

Maintenance

• Oil Check : Check and replace compressor oil regularly to ensure adequate lubrication and prevent premature wear.
• Cleaning the Filters : Clean or replace the filters to keep the compressed air clean and ensure the correct functioning of the unit.
• Cooling System Inspection : Make sure the cooling fan and radial cooling system are functioning properly and that there are no obstructions.
• Periodic Check : Perform regular checks on all electrical connections and the control panel to ensure that the compressor is operating optimally.

Evaluation of Good Used

• Visual Condition : Examine the unit for any signs of wear or damage. A good quality used compressor should appear well maintained and free of significant damage.
• 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

• Small workshops and craftsmen : Perfect for work environments where compact dimensions and silence are required.
• Laboratories and Precision Environments : Used for applications requiring high quality compressed air without excessive noise.
• Small Industrial Businesses : Suitable for operations requiring a constant flow of compressed air for machinery and tools.

Advantages of Buying Used

• Lower Cost : Purchasing a used Dari DSB 8 compressor allows you to get a high quality unit at a more competitive price than new.
• Immediate Availability : A used compressor can be ready for immediate use, reducing waiting times.
• Reliability : A well-maintained used compressor can offer performance comparable to that of a new compressor, with the advantage of a lower initial cost.

Conclusion

The used Dari DSB 8 rotary screw compressor, with a power of 7.5 kW (10 HP) and a flow rate of 970 liters per minute, represents an excellent solution for those looking for efficiency and silence at a low cost. Thanks to its separate radial cooling fan and its robustness, it is suitable for a wide range of industrial and craft applications.
