Quantity: 

Suitable for 10–15 dental comprehensive treatment units.

Equipment Use:

Used as the power source for high-speed turbine dental handpieces or low-speed pneumatic handpieces during dental treatment procedures such as tooth drilling. 

Operating Conditions :

Environmental Conditions :

1. Ambient temperature: 5°C – 40°C
   
2. Relative humidity: ≤ 70%
   
3. Atmospheric pressure: 86 – 106 kPa
   
4. Ventilation flow rate: ≥ 0.10 m³/s
   
   

Power Supply Requirements:

1. Rated voltage: AC 220 V ±10%
   
2. Frequency: 50 Hz
   
3. Rated power: ≤ 4.5 kW
   
4. Starting pressure: 0.45 MPa
   
5. Stopping pressure: 0.75 MPa
   
6. Noise level: ≤ 79 dB
   
7. Air tank capacity: 150 L
   

Technical Specifications :

1. Oil-free piston-type air compressor; motor speed: ≥ 1400 rpm; nominal flow rate: 130 L/min (at 0.5 MPa); total system flow rate: 520 L/min (at 0.5 MPa);
   
2. Four compressor heads operated in parallel, equipped with a 150 L air storage tank, sufficient for powering 10–15 dental comprehensive treatment units (at 0.5 MPa);
   
3. The air storage tank is internally treated for rust prevention with nano-antibacterial coating to ensure a clean and hygienic air supply;
   
4. Equipped with an intake filter that effectively filters out most dust particles and pathogens;
   
5. The four motors are started sequentially in time-sharing mode to reduce starting current;
   
6. Each motor can be started and stopped independently, serving as a backup for the others;
   
7. Equipped with a high-precision safety valve; when the pressure inside the air storage tank exceeds 0.85 MPa, the safety valve opens immediately;
   
8. Microcomputer controller with under-voltage protection and overcurrent protection;
   
9. Features an automatic drainage valve for scheduled drainage to prevent water accumulation in the tank and extend the service life of high-and low-speed mobile air compressors;
   
10. An optional air dryer can be installed according to operational requirements, with a pressure dew point of up to-20°C;
    
11. External dimensions (length × width × height): ≤140 × 54 × 85 cm;
    
12. Weight: ≤120 kg
