PreAsion 15L Circulating Water Vacuum Pump Water Jet Aspirator Anti-Corrosion Lab Instruments 2 Off-Gas Taps 110V 60L/min

【Applications Widely】This machine is used to provide vacuum condition for the process of evaporation, distillation, crystallization, drying, sublimation, filtration, decompression, degassing and so on, particularly be suitable for labs and small scale test of industries such as universities and colleges, scientific research institutes. 【Operation Steps 】1. On first use, open the upper cover of the water tank and inject cold water till the water level reaches the height of the upper water outlet. 2. Link tightly the tube to the sucking tap. Then put through the power and the pump begins to work. 3. If the machine need to work for a long time, the temperature of the tank water will rise effecting the vacuum degree. At this time, connect the drain hose with tap water and drain water from the water outlet. 【Upgraded Machine】This machine is upgraded with anti-corrosion and anti-rust copper, which will avoid the devices be contaminated. 【Suitable for Different Circumstance】 It can be operated with single tap or use the both taps simultaneously for higher efficiency. Large 15L Water Tank, With Removable Case For Quick Water 【Safety and Silent】Silent Use With Special Fluid Muffler, Reduce The Noise And Liquid Friction. Have Check Valve On Exhaust Tube, Which Can Prevent Vacuum Unplanned Downtime On Working.
