Product Description
Oil Free Less Scroll Dental Electrical Driven Air Compressor (KDR1108)
Rotary scroll oil free compression is realized by rotational motion of static plate and moving plate.
The air is sucked in from the suction port at the outside of the fixed scroll. The air enclosed in the confined space is compressed towards the center when the compression chamber is becoming smaller due to the rotation movement. The compressed space becomes smallest at the center, and the air compressed to the highest limit is discharged out from the central exhaust port. The movement Figure 1-4 (Suction-Compression-Exhaust) is repeated thereby to produce compressed air without pulsation .
High reliability:
KDR series rotary scroll air compressor is designed with few moving parts, only 1/8 of rotary screw air compressor, so it realizes higher mechanical reliability.
In order to ensure rotary scroll oil free pump head cooling efficiency, every rotary scroll oil free air compressor is cooled by big capacity fan and aftercooler, and every scroll head is equipped with a standalone cooling fan. Even in high ambient temperature, the compressor is able to run steadily.
Full KDR series scroll head is designed for modularization. If 1 scroll compressor head is failed during operation, there will have no influence to others, the modularization design improves operational safety of the unit and avoids down time to customer’s production.
There is no risk of oil contamination to air system or to end products.
The main pipe in system made from stainless steel is able to ensure the quality of compressed air further.

Are There Specific Filtration Requirements for Oil-Free Scroll Compressors?
Yes, there are specific filtration requirements for oil-free scroll compressors to ensure the maintenance of air quality. Here’s a detailed explanation:
Intake Air Filtration:
Oil-free scroll compressors require effective intake air filtration to prevent the entry of particulates and contaminants into the compressor system. The intake air filters should have a high filtration efficiency and be capable of capturing particles of various sizes. These filters are typically installed at the compressor’s intake or inlet, where they remove dust, dirt, pollen, and other airborne impurities from the incoming air. The use of high-quality intake air filters helps protect the compressor’s internal components and ensures that the compressed air remains clean and free from contaminants.
Coalescing Filters:
In addition to intake air filters, oil-free scroll compressor systems may incorporate coalescing filters for enhanced air quality. Coalescing filters are designed to remove oil aerosols and fine moisture droplets from the compressed air. These filters utilize specialized media that coalesce the oil and water particles into larger droplets, which are then separated and drained from the compressed air. Coalescing filters are particularly important in applications where the presence of oil or moisture can negatively impact downstream processes or equipment.
Particulate Filters:
Particulate filters, also known as dust filters or general-purpose filters, are used in oil-free scroll compressor systems to remove solid particles from the compressed air. These filters are designed to capture particles of various sizes and can effectively remove dust, dirt, rust, and other solid contaminants. Particulate filters are typically installed downstream of the compressor to ensure that the compressed air remains free from any remaining particles that may have bypassed the intake air filtration stage.
Activated Carbon Filters:
Activated carbon filters, or adsorption filters, are used in oil-free scroll compressor systems to remove odors and certain types of gases. These filters contain activated carbon media that adsorb and trap gas molecules onto their porous surfaces. Activated carbon filters are effective in removing odors, hydrocarbons, volatile organic compounds (VOCs), and other specific gases that may be present in the compressed air. They are commonly used in applications where odor control or gas removal is essential, such as in the food and beverage industry or laboratories.
Filter Maintenance and Replacement:
Proper maintenance and regular replacement of the filtration components are essential to ensure their optimal performance and prevent any degradation in air quality. The maintenance intervals and replacement schedules for filters may vary depending on factors such as operating conditions, air quality requirements, and the specific recommendations of the filter manufacturer. Regular inspections, cleaning or replacement of filters, and adherence to maintenance schedules are necessary to maintain the required filtration efficiency and prevent any potential contamination of the compressed air.
It is important to consult the compressor manufacturer’s guidelines and recommendations regarding the specific filtration requirements for their oil-free scroll compressor models. They can provide detailed information on the types of filters to be used, their location within the compressor system, recommended maintenance procedures, and replacement intervals. Adhering to these requirements ensures that the filtration system effectively removes contaminants and maintains the desired air quality in oil-free scroll compressor systems.

Can Oil-Free Scroll Compressors Handle High-Pressure Applications?
Oil-free scroll compressors are primarily designed for medium to low-pressure applications. Here’s a detailed explanation:
Operating Pressure Range:
Oil-free scroll compressors are generally suitable for applications that require operating pressures up to a certain limit. The exact pressure range can vary depending on the specific model and manufacturer, but most oil-free scroll compressors are designed for pressures typically ranging from 7 to 15 bar (100 to 220 psi). Some specialized models may be capable of higher pressures, but they are less common.
Scroll Compressor Design:
The design of oil-free scroll compressors is optimized for efficient operation at medium to low pressures. The scroll compressor consists of two interleaved spiral scrolls—one fixed and one orbiting—that create compression chambers. As the orbiting scroll moves, it traps and compresses the air between the scrolls, resulting in compressed air being discharged. The design and geometry of the scrolls are typically optimized for specific pressure ranges, and they may not be suitable for extremely high-pressure applications.
Limited Compression Ratios:
Oil-free scroll compressors have limitations in terms of compression ratios, which affect their ability to handle high pressures. The compression ratio is the ratio of the discharge pressure to the suction pressure. As the compression ratio increases, so does the temperature of the compressed air. Oil-free scroll compressors are not designed to handle very high compression ratios, as they can lead to excessive temperatures, increased wear on components, and reduced efficiency.
Adequate Cooling:
High-pressure applications often require effective cooling to manage the heat generated during compression. Oil-free scroll compressors may have limitations in terms of cooling capacity, which can affect their ability to handle high-pressure operation. In applications with high-pressure requirements, additional cooling measures may be necessary to maintain optimal operating temperatures and prevent overheating of the compressor.
Alternative Compressor Types:
For high-pressure applications, alternative compressor types such as reciprocating compressors, rotary screw compressors, or centrifugal compressors are more commonly used. These compressor types are specifically designed to handle higher pressures and provide better efficiency and performance in such applications.
It’s important to consult the manufacturer’s specifications and guidelines to determine the maximum operating pressure for a specific oil-free scroll compressor model. Exceeding the recommended pressure limits can lead to premature wear, reduced efficiency, and potential compressor failure.
In summary, oil-free scroll compressors are generally not designed to handle high-pressure applications. They are more suitable for medium to low-pressure applications within their specified operating pressure range. For high-pressure requirements, alternative compressor types should be considered.
