2. Frequency: 50 Hz/60 Hz;
   
3. Rated Power: ≤ 2.5 kW / 2.75 kW;
   
4. Rated Current: 15.8 A / 16.3 A; 
   
5. Installation Location: Install on a floor one level below the dental comprehensive treatment console floor;
   
   

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: -16 kPa;
   
2. High suction flow rate: When P = 0 kPa, the suction capacity of a single vacuum pump is approximately 2400 L/min; the suction capacity of the entire unit is approximately 4800 L/min; when P = -15 kPa, the suction capacity of a single vacuum pump is approximately 750 L/min; the suction capacity of the entire unit is approximately 1500 L/min; operates with two vacuum pumps connected in parallel, supporting up to 8 dental comprehensive treatment units; 
   
3. Two high-flow vacuum pumps are operated in parallel; they can be started simultaneously via time-sharing control or operate independently as backup units, providing the highest level of reliability for the outpatient department.
   
4. The system features an integrated modular semi-dry suction system, including an independent separation tank and an independent wastewater pump, enabling continuous active discharge of wastewater; 
   
5. An intelligent microcomputer control system allows independent control of the operating status of each vacuum pump, incorporates multiple circuit protection functions, and includes an automatic delayed shutdown feature;
   
6. Equipped with motor overload protection that automatically shuts down the equipment when it operates under excessive load or when a pipeline becomes blocked;
   
7. Utilizes Mitsubishi variable frequency drive technology combined with a PID algorithm control system to ensure stable negative pressure output;
   
8. One-touch emergency startup function: in the event of a microcomputer system failure, the system can be activated via a single button press to enter emergency mode, ensuring uninterrupted operation of the outpatient department while awaiting maintenance or rescue services;
   
9. A remote monitoring system provides real-time monitoring of equipment performance, issues early warnings regarding the service life of equipment components or consumables, and allows users to query equipment fault codes, operating time, parameters, and more;
   
10. The mechanical negative pressure balancing valve ensures adequate fresh air supply for internal cooling and heat dissipation of the suction pump, while preventing the pump from being damaged due to pipeline blockage; 
    
11. A high-capacity stainless steel separation tank featuring a high-precision water level sensor, automatic drainage function, and automatic flushing function;
    
12. Equipped with a high-precision exhaust filter that effectively prevents the accumulation of dust and bacteria, with a filtration efficiency of up to 97%.
    
13. Noise level: ≤75 dB(A)
    
14. External dimensions (height × width × length): ≤107 × 70 × 103 cm
    
15. Net weight: ≤122 kg
