Capacity:

Suitable for use with 35–40 dental combined treatment units. 

Equipment Purpose: 

This device serves as a suction power source for extracting saliva, blood, or small particles during dental 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: ≥ 0.40 m³/s
   
5. Power Supply Requirements
   
6. Rated voltage: AC 380 V ±10%
   
7. Frequency: 50 Hz 
   
8. Rated power: ≤ 9 kW
   

Technical Specifications :

1. Air-ring suction pump; motor speed: ≥ 2800 r/min – enables instantaneous generation of high suction flow rates 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 ≥ 18000 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 ≥ 8400 L/min. Four vacuum pumps are operated in parallel to accommodate up to 35–40 dental comprehensive treatment units;
   
3. Features an integrated modular dry suction system with an independent wastewater pump capable of 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 Siemens PLC and microcomputer control system, when 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 and 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: ≤80 dB(A);
   
9. External dimensions: (Height × Width × Length) ≤127 × 78 × 115 cm (main unit) or 60 × 60 × 112 cm (separate tank);
   
10. Net weight: ≤320 kg.
