Adopting oil-free piston pump
Clean: without pollution of oil and smoke
Convenient: no need add oil to maintain daily
Safe: no extra pressure while using
Max negative pressure: ≥0.09Mpa
Noise:≤ 65 dB (A)
Power: ≤180VA
Pumping rate: ≥20L/min
Reservoir capacity: 2500mL/pc, 2pieces
Electrical appliance safety requirement: Class I, Type B
Max continuous working time is 30 minutes, continuity rate: 50%
No flow backwards pressure when the machine stops,so the liquid won’t flow backwards
