Quantity: 

Suitable for 7–10 dental combined treatment units. 

Equipment Use: 

This device is designed for use as a suction power source during dental procedures (e.g., tooth drilling) at hospitals or dental clinics for the aspiration of saliva, blood, or small particles; it 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: ≥ 0.10 m³/s;
   

Power Supply Requirements :

1. Rated Voltage: AC 220 V ±10%;
   
2. Frequency: 50 Hz;
   
3. Rated Power: 3 kW;
   

Technical Specifications :

1. Water-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: –50 kPa;
   
2. High suction flow rate: When operating under a negative pressure of –120 mBar, the flow rate of a single suction pump is ≥ 1000 L/min, sufficient for the simultaneous operation of four dental unit systems (total flow rate: 250 L/min);
   
3. Vertical design saves installation space while preventing bearing damage or seal failure caused by unilateral load-bearing during horizontal installation, thereby preventing liquid ingress into the motor and potential motor burnout;
   
4. Intelligent microcomputer control system allows independent control of the operating status of each vacuum pump, features multiple circuit protection functions, and includes an automatic delayed shutdown function;
   
5. A mechanical negative pressure balancing valve ensures the negative pressure remains within the optimal range of 110–150 mbar, preventing excessive negative pressure from damaging the patient's oral mucosa;
   
6. A NEMA-certified high-efficiency motor specifically designed for this device, featuring a stainless steel spindle paired with a stainless steel impeller and pump body – distinct from the cast-iron pump bodies used in other wet suction systems available on the market;
   
7. Noise level: ≤75 dB(A);
   
8. External dimensions (height × width × length): ≤50 × 40 × 70 cm
