Zhengzhou Great Wall produces different models of Bench-top Water Circulating Vacuum Pumps including SHB-Ⅲ, SHB-ⅢA, SHB-ⅢS, SHB-ⅢG. Vacuum level is directly affected by water temperature.
Vacuum level is the highest when water temperature is around +5℃. When vacuum pumps work continuously for a long time, water temperature will rise, which may affect vacuum level. Please change tap water frequently. .
