Capacity: 

Suitable for use with 25–30 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 :

Environmental Conditions :

1. Ambient Temperature: 5°C – 40°C
   
2. Relative Humidity: ≤ 70%
   
3. Atmospheric Pressure: 86 – 106 kPa
   
4. Ventilation Flow Rate: ≥ 0.40 m³/s
   
5. Power Supply Requirements
   
6. Rated Voltage: AC 380 V ±10%
   
7.  Frequency: 50 Hz
   
8. Rated Power: ≥ 7 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: –22 kPa.
   
2. High suction flow rate: When P = 0 kPa, the suction capacity of a single vacuum pump is ≥ 4500 L/min; the total suction capacity of the unit is ≥ 13500 L/min; when P = –15 kPa, the suction capacity of a single vacuum pump is ≥ 2100 L/min; the total suction capacity of the unit is ≥ 6300 L/min. Three vacuum pumps are operated in parallel to accommodate up to 25–30 dental comprehensive treatment units;
   
3. Features an integrated modular dry suction system with an independent wastewater pump for continuous, active wastewater discharge; includes a high-efficiency stainless steel separation tank, a high-precision liquid level sensor, and an automatic flushing and cleaning system within the tank.
   
4. The microcomputer-controlled system, integrated with an intelligent management system, enables independent control of the operating status of each vacuum pump; each pump can be started and stopped individually or operated in a rotating sequence to ensure equal operating time for all pumps, thereby extending their service life; the system features multiple circuit protection functions and an automatic delayed shutdown function.
   
5. The remote monitoring system ensures the reliable and efficient operation of the equipment.
   
6. The built-in mechanical negative pressure balancing valve maintains the negative pressure within the optimal range of 140–180 mbar, preventing damage to the patient's oral mucosa caused by excessively high negative pressure;
   
7. The mechanical negative pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation within the suction pump;
   
8. Noise level: ≤79 dB(A);
   
9. External dimensions: (Height × Width × Length) ≤150 × 65 × 100 cm (main unit) or 50 × 50 × 140 cm (separate tank);
   
10. Net weight: ≤320 kg.
