Quantity: 

Suitable for use with 4–6 dental combined treatment units. 

Equipment Purpose:

 Used as a suction power source for aspirating saliva, blood, small particles, or other fluids 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 :

1 .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; 4.2.3 Rated power: 1.9 kW;
   
   

Technical Specifications: 

1. Air-ring suction pump – Motor speed: ≥ 2800 rpm; capable of instantly generating a high suction flow rate compliant with dental application standards without any waiting time; Maximum vacuum: –19 kPa;
   
2. High suction flow rate: ≥ 1000 L/min at a negative pressure of –15 kPa; supports up to 6 dental combined treatment units; 
   
3. Features an integrated modular wet-suction structure equipped with a two-stage water–gas separation system and an active gas–liquid separator; 
   
4. The gas–liquid separator incorporates a two-stage separation function; Liquid handling capacity: ≥ 20 L/min; 
   
5. The entire machine casing and components are manufactured from electroplated anti-corrosive aluminum alloy or high-strength anti-corrosive plastic, extending the service life of the equipment;
   
6. Microcomputer controller with multiple circuit protection functions and an automatic delayed shutdown feature;
   
7. Built-in mechanical negative pressure balancing valve ensures the negative pressure remains within the optimal range of –14 kPa – –18 kPa, preventing excessive negative pressure from damaging the patient's oral mucosa; 
   
8. The mechanical negative-pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation of the suction pump, while preventing damage to the suction pump caused by pipeline orifices;
   
9. Built-in wastewater pump enables continuous automatic discharge of wastewater;
   
10. Built-in drainage diaphragm valve prevents backflow of wastewater into the suction pump;
    
11. Equipped with an exhaust filter featuring a built-in silver-ion-coated filter element, providing both filtration and sterilization functions;
    
12. Noise level: ≤68 dB(A)
    
13. External dimensions (height × width × depth): ≤92 × 44 × 70 cm;
    
14. Weight: ≤70 kg
