Quantity: 

Suitable for 8–10 dental comprehensive treatment units. 

Equipment Use: 

This device serves 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; 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: ≥ 0.20 m³/s
   

 Power Supply Conditions

    1 .Rated Voltage: AC 220 V ±10% 

    2. Frequency: 50 Hz/60 Hz 

    3. Rated Power: ≤ 3 kW/3.2 kW 

    4 .Rated Current: 20 A/22.5 A

Installation location: 

Installed on the same floor as the dental comprehensive treatment unit.

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; Maximum vacuum: -20 kPa;
   
2.  High suction flow rate: At P = 0 kPa, the suction capacity per unit 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 per unit 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 the operation of 8–10 dental comprehensive treatment units;
   
3.  Features an integrated modular semi-dry suction system and an independent water-air separation system, making it suitable for installation scenarios where the treatment unit and suction system are located on the same floor;
   
4.  Intelligent microcomputer control system – enables independent control of the operating status of each suction pump; the two vacuum pumps serve as mutual backups; includes multiple circuit protection functions and an automatic delayed shutdown feature;
   
5.  Built-in mechanical negative pressure balancing valve – ensures the negative pressure remains within the optimal range of 15–18 kPa, preventing excessive negative pressure from damaging the patient's oral mucosa;
   
6. The mechanical negative pressure balancing valve provides sufficient fresh air for internal cooling and heat dissipation of the suction pump, while also preventing damage to the suction pump due to pipeline blockage;
   
7.  One-touch emergency start function – in the event of a microcomputer system failure, the device can be activated via a single button to enter emergency mode, allowing the workstation to continue operating while awaiting maintenance or rescue support;
   
8.  Remote monitoring system – ensures the reliable and smooth operation of the equipment; You can check the device's operating status directly on your mobile device.
   
9. Noise level: ≤75 dB(A)
   
10.  External dimensions (height × width × length): ≤125 × 65 × 97 cm
    
11.  Net weight: ≤95 kg
