Adopting oil-free lubrication pump, square negative pressure dial and built-in bottle. Low noise, small size, easy to carry. It adopts three modes to supply electricity: alternating current, direct current and batteries. So it is more suitable for lack of alternating current situation such as on vehicles and outdoor places to save and nurse patients. Power supply: AC 220V±10%, 50Hz±2%,12VDC Power: ≤90VA Max negative pressure value: ≥0.075MPa Pumping rate: ≥15L/min Reservoir volume: 1000mL Noise: ≤65dB(A)
