KJ-3EW
FSKEJU
KJ-3EW
The FSKEJU KJ-1EW dental air compressor is a 32L oil-free compressed-air system designed for single-chair dental clinic applications. With 550W rated power, 65L/min airflow and a pressure specification of 7.5 bar, the KJ-1EW provides a dedicated compressed-air supply for one compatible dental chair.
The one-for-one configuration makes the KJ-1EW suitable for treatment rooms where an individual dental unit requires its own compressor rather than sharing a larger centralized compressed-air system.
Additional capacities for single-chair and multi-chair installations can be reviewed in our Dental Air Compressor range.
KJ-1EW Product Snapshot
Model: KJ-1EW
Product Type: Oil-Free Dental Air Compressor
Chair Configuration: One for One
Tank Capacity: 32L
Power: 550W
Rated Airflow: 65L/min
Pressure: 7.5 bar
Noise Level: 65 dB
The KJ-1EW is configured as a one-for-one dental air compressor for supplying compressed air to one compatible dental treatment unit under an appropriate clinic installation.
A dedicated compressor can be useful in a single-operatory clinic, an independent treatment room or an installation where each dental chair uses a separate compressed-air source.
“One for one” describes the intended chair configuration rather than replacing an airflow assessment. Dental units and air-driven instruments can have different compressed-air requirements, so the actual equipment demand should be reviewed before installation.
The KJ-1EW uses an oil-free compressor design, meaning lubricating oil is not introduced into the compression process during normal operation.
For a dental clinic, the compressor is only one part of the complete compressed-air system. Intake conditions, filtration, moisture management, receiver-tank maintenance, piping and connections also influence the air delivered to the treatment unit.
Oil-Free Does Not Mean Maintenance-Free
The oil-free compressor design removes the need for lubrication oil within the compression process, but the complete system still requires inspection and maintenance according to the applicable operating instructions.
The KJ-1EW provides a rated airflow of 65L/min. Airflow is one of the main parameters to consider when matching a dental compressor to a treatment unit because it indicates how much compressed air the compressor can deliver over time.
For a single-chair system, the dental chair and any air-driven instruments should be reviewed together. If their combined air demand exceeds the available compressor output during operation, tank capacity alone will not solve the sizing issue.
Key Capacity Figures
65L/min airflow + 32L receiver tank + one-chair application are the main capacity references for evaluating the KJ-1EW against a dental unit's compressed-air requirements.
The KJ-1EW is equipped with a 32L air receiver. The receiver stores compressed air and provides a buffer between compressor output and changing demand from the connected dental equipment.
Tank capacity should not be used alone to compare dental compressors. A larger tank does not automatically mean that a compressor can support more equipment. Airflow, pressure, equipment demand and expected operating pattern should be considered together.
The KJ-1EW has a pressure specification of 7.5 bar. The required air pressure at the dental unit should be checked against the treatment equipment specification before the compressor is installed.
Pressure available at the treatment unit can also be affected by piping length, internal diameter, fittings and other components between the compressor and dental chair.
The KJ-1EW has a specified noise level of 65 dB, providing a measurable reference when planning compressor placement within or near a dental treatment room.
Actual perceived sound inside a dental clinic can vary according to compressor location, room construction, ventilation, distance from the treatment area and vibration transmission.
Noise Planning Note
If acoustic performance is important to your project, consider both the 65 dB equipment specification and the planned installation environment when selecting the compressor location.
The KJ-1EW is available in 110V/60Hz and 220V/50Hz configurations. Please specify the required version according to the destination market and clinic electrical supply before ordering.
Electrical installation should also take the compressor's 550W rated power into account and follow the applicable local electrical and equipment-installation requirements.

The KJ-1EW is designed for one dental chair. For clinic planning, compare the compressor's 65L/min rated airflow and 7.5 bar pressure specification with the requirements of the treatment unit and connected air-driven equipment.
✓ Dental chair model: identify the treatment unit that will use the compressor.
✓ Required airflow: compare the chair and instrument demand with the KJ-1EW 65L/min output.
✓ Required pressure: check the dental unit's specified compressed-air inlet requirement.
✓ Air-driven instruments: consider the equipment that may operate during normal treatment.
✓ Pipe layout: account for pipe length, fittings and possible system pressure loss.
✓ Future expansion: if a second treatment unit may be added, consider whether a larger multi-chair compressor would be more appropriate.
The KJ-1EW is intended for a one-chair configuration, while our larger compressor models are available for installations serving multiple dental treatment units.
Selection Factor | KJ-1EW | Larger Multi-Chair Compressor |
|---|---|---|
Clinic Layout | Single treatment chair | Several treatment chairs sharing one air source |
Air Distribution | Dedicated connection to one chair | Shared distribution system |
Sizing Priority | Single-chair airflow requirement | Combined and simultaneous airflow demand |
Expansion Planning | Suitable when one-chair demand is expected to remain stable | Consider when several chairs or future expansion are planned |
The compressor should be installed in a location that provides suitable ventilation, access for inspection and maintenance, and an appropriate compressed-air route to the dental chair.
The installation area should also account for the 65 dB noise specification and avoid unnecessary restriction around the compressor that could affect ventilation.
The compressed-air line between the compressor and dental unit should be planned according to the treatment-room layout and equipment requirements.
The KJ-1EW uses an oil-free compressor design, but routine equipment inspection remains necessary. Follow the operating and maintenance instructions supplied with the compressor.
The air receiver, drainage arrangement, filters where fitted, tubing connections, electrical components and ventilation condition should be inspected according to the applicable maintenance schedule.
For projects that require defined maintenance intervals or spare-part planning, please contact our team for the applicable manual and replacement-part information.
✓ Dental chair requirement: check that the connected equipment is suitable for the KJ-1EW airflow and pressure specification.
✓ Voltage: specify 110V/60Hz or 220V/50Hz according to the destination market.
✓ Installation environment: consider ventilation, maintenance access and compressor noise.
✓ Air distribution: review piping and connection requirements between the compressor and dental chair.
✓ Packing information: request carton dimensions and gross weight where freight planning is required.
✓ Documentation: specify any technical or regulatory documents required for the destination market.
✓ Spare parts and service: clarify replacement-part and after-sales requirements for long-term equipment support.

The rated airflow is 65L/min.
The KJ-1EW has a rated power of 550W.
Yes. The KJ-1EW uses an oil-free compressor design for dental compressed-air applications.
The KJ-1EW has a specified noise level of 65 dB. Actual perceived sound after installation can also be influenced by room construction, ventilation, vibration transmission and compressor placement.
The KJ-1EW is available in 110V/60Hz and 220V/50Hz configurations. Please specify the required electrical version when ordering.
The KJ-1EW is designed for one dental chair. If two treatment units require a shared compressed-air supply, select a compressor sized for the combined airflow demand rather than assuming that a one-chair model can support both units.
