Number of dental chairs compatible: 

Suitable for up to 60 dental chair units. 

Equipment: 

Used as a suction power source for aspirating spray, saliva, blood, or small particles during dental treatment procedures (e.g., tooth drilling) in hospital or dental clinic settings; also features a water vapor separation and automatic discharge function. 

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: ≥ 0.30 m³/s
   
   

Power Supply Requirements :

1. Rated voltage: AC 380 V ±10%
   
2. Frequency: 50 Hz
   
3. Rated power: 16.5 kW
   

Technical Specifications :

1. Air-ring suction pump: 4 kW per unit; motor speed: ≥ 2800 rpm – capable of instantaneously generating high suction flow rates compliant with dental application standards without any waiting time; maximum vacuum: –26 kPa
   
2. High suction flow rate: When the suction system operates under a negative pressure of –150 mBar, the flow rate is ≥ 18,000 L/min – sufficient for 100% simultaneous operation of 60 dental chair units (with a required flow rate of 300 L/min per dental chair). 
   
3. Four high-flow vacuum pumps are connected in parallel; they can operate independently or in conjunction with time-sharing startup, serving as mutual backups to provide the highest level of reliability for outpatient dental care.
   
4. Features an integrated modular wet suction system with an independent wastewater pump capable of continuous active wastewater discharge; a high-efficiency stainless steel separation tank equipped with a high-precision level sensor and an internal flushing and cleaning system;
   
5. The separation tank incorporates a built-in sterilization function that disrupts the structure of viable bacteria, achieving a sterilization efficiency of up to 99%;
   
6. Intelligent microcomputer control system allows independent control of the operating status of each vacuum pump, featuring multiple circuit protection functions and an automatic delayed shutdown function;
   
7. Siemens touchscreen (7-inch) enables independent control of the equipment's operating status, as well as viewing real-time operating parameters and fault codes;
   
8. Utilizes variable frequency drive technology combined with a PID algorithm control system to ensure stable negative pressure output;
   
9. High-precision pressure sensor provides the workstation with a constant negative pressure value;
   
10. External mechanical negative pressure balancing valve ensures the negative pressure value remains within the optimal range of 110–150 mbar, preventing excessive negative pressure from damaging the patient's oral mucosa;
    
11. One-touch emergency startup function: in the event of a microcomputer system failure, the device can be activated via a single button press to enter emergency mode, allowing operation to continue while awaiting maintenance support;
    
12. The mechanical negative pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation of the suction pump;
    
13. High-efficiency exhaust filter with a built-in silver ion filter element effectively inactivates bacteria and viruses at the exhaust outlet;
    
14. Noise level: ≤75 dB(A);
    
15. External dimensions (Height × Width × Length): ≤140 × 80 × 120 cm (Main Unit) or 60 × 60 × 112 cm (Separation Tank);
    
16. Net weight: ≤320 kg
