Capacity: 

Suitable for use with 90–100 dental chair 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 hospitals or dental clinics; 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: ≥ 0.50 m³/s;
   
5. Machine room area: ≥ 20 m²;
   
6. Power Supply Requirements:
   
7. Rated voltage: AC 380 V ±10%;
   
8. Frequency: 50 Hz;
   
9. Rated power: ≤ 25 kW.
   
   

Technical Specifications:

1. Air-ring suction pump – Motor speed: ≥ 2800 r/min; capable of instantaneously 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 operating at a negative pressure of –140 mBar, the suction capacity per unit pump is ≤ 5500 L/min; the maximum total suction capacity of the unit is ≤ 22,000 L/min; supports up to 100 dental chair stations.
   
3. Features an integrated modular semi-dry suction system with independent wastewater pumps capable of continuous, active wastewater discharge;
   
4. The Siemens PLC intelligent control system, when combined with an intelligent management system, enables independent control of the operating status of each vacuum pump; this allows each vacuum pump to be started and stopped individually and operated in a rotating sequence, ensuring each pump operates for the same duration and thereby extending its service life; the system incorporates multiple circuit protection functions, including an automatic delayed shutdown feature.
   
5. 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;
   
6. The mechanical negative pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation within the suction pump;
   
7. Noise level: ≤80 dB
   
8. External dimensions (height × width × length): ≤140 × 80 × 120 cm (main unit); ≤60 × 60 × 112 cm (separate tank);
   
9. Net weight: ≤320 kg
