Technical Specifications: 

1. Air-ring suction pump; Motor speed: ≥2800 r/min – capable of instantly generating a high suction flow rate compliant with dental application standards without requiring prolonged waiting time; Maximum vacuum: -20 kPa;
   
2. High suction flow rate: At P = 0 kPa, the suction capacity of a single vacuum pump is approximately 3000 L/min; the total suction capacity of the unit is approximately 6000 L/min; At P = -15 kPa, the suction capacity of a single vacuum pump is approximately 1700 L/min; the total suction capacity of the unit is approximately 3400 L/min. Two vacuum pumps are operated in parallel to accommodate 8–10 dental unit systems;
   
3. Features an integrated modular semi-dry suction system, including an independent separation tank and an independent wastewater pump, enabling continuous active wastewater discharge;
   
4. Intelligent microcomputer control system that allows independent control of the operating status of each suction pump, incorporates multiple circuit protection functions, and includes an automatic delayed shutdown function; 
   
5. Built-in mechanical negative pressure balancing valve ensures the negative pressure value remains within the optimal range of 15–18 kPa, preventing excessive negative pressure from damaging the patient's oral mucosa;
   
6. One-touch emergency startup function: in the event of a microcomputer system failure, the device can be activated via a single button to enter emergency mode, ensuring uninterrupted outpatient service while awaiting maintenance and rescue support;
   
7. Remote monitoring system provides real-time monitoring of equipment operation status, offers early warnings regarding the remaining lifespan of consumables or components, and allows users to query equipment fault codes, operating time, parameters, and more;
   
8. The mechanical negative pressure balancing valve ensures an adequate supply of fresh air for internal cooling and heat dissipation of the suction pump, while preventing the suction pump from being damaged due to pipeline blockage; 
   
9. A high-capacity 100L stainless steel separation tank featuring a high-precision water level sensor, automatic drainage function, and automatic flushing function;
   
10. Noise level: ≤75 dB(A);
    
11. External dimensions of the negative pressure unit (height × width × length): ≤107 × 70 × 103 cm; Dimensions of the separation tank (height × width × length): ≤50 × 50 × 110 cm; 
    
12. Net weight: ≤125 kg
