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
    

Q1: How many dental units can this compressor support? 

A: This compressor is equipped with 4 parallel compressor heads and a 150L air tank, which can stably support 10–15 dental comprehensive treatment units, suitable for medium and large dental clinics.

Q2: Is the output compressed air clean and oil‑free? 

A: Yes. It adopts an oil‑free piston design. The air tank has nano antibacterial and anti‑rust coating, matching an intake filter to block dust and impurities, providing hygienic and qualified air for dental treatment.

Q3: Can this machine maintain stable air pressure?

A: Yes. The working pressure ranges from 0.45 MPa to 0.75 MPa. Four independent parallel motors effectively reduce pressure fluctuation, ensuring stable air supply for dental handpieces.

Q4: Is this compressor low noise for clinic use?

A: Yes. The operating noise is ≤79dB. Adopting sequential starting technology, it reduces current impact and running noise, creating a quiet clinic environment.

Q5: What safety protection functions does it have?

A: It is equipped with a high‑precision overpressure safety valve, under‑voltage and overcurrent protection, as well as an automatic timed drainage system, ensuring safe and long‑term stable operation.

Q6: Is an air dryer optional for this compressor?

A: Yes. The optional air dryer can reach a pressure dew point of ‑20°C, effectively removing moisture and protecting dental equipment and handpieces.
