Capacity: 

Suitable for 10–15 dental comprehensive treatment units.

Equipment Use: 

Used as a suction power source for aspirating 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: 3.3 kW.
   
   

Technical Specifications: 

1. Air-ring suction pump – Motor speed: ≥ 2800 rpm; capable of instantaneously generating a high suction flow rate compliant with dental application standards without any waiting time; maximum vacuum: –19 kPa.
   
2. High suction flow rate: When operating at a negative pressure of –140 mBar, the flow rate of a single suction pump is ≥ 1600 L/min, sufficient for the simultaneous operation of 5 dental comprehensive treatment units (total flow rate: 300 L/min)..
   
3. Two high-flow vacuum pumps operate in parallel; they can be started sequentially or function independently as backup units, providing maximum reliability for outpatient dental care. 
   
4. Features an integrated modular semi-dry aspiration system, including an independent separation tank and an independent wastewater pump, enabling continuous, active wastewater discharge;
   
5. Equipped with an intelligent microcomputer control system that allows independent control of the operating status of each vacuum pump, featuring multiple circuit protection functions and an automatic delayed shutdown function;
   
6. External mechanical negative pressure balancing valve ensures the negative pressure remains within the optimal range of 110–150 mbar, preventing damage to the patient's oral mucosa caused by excessively high negative pressure;
   
7. 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 it to continue operating while awaiting maintenance or rescue support;
   
8. The mechanical negative pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation of the aspiration pump;
   
9. Noise level: ≤75 dB(A);
   
10. External dimensions (Height × Width × Length): ≤107 × 70 × 103 cm (Main unit) or 60 × 60 × 112 cm (Separation tank);
    
11. Net weight: ≤95 kg
