18V LXT • 4CFM class 4 CFM class vacuum pump for air purge during installation of air large conditioning systems DVP181 adopts dual-stage compression method, which can generate vacuum level much higher than the single-stage compression method. This high power enables DVP181 to purge large air conditioning systems such as 20hp class industrial refrigerating showcases or air conditioners for office use. This model gives a long runtime of 60 minutes which is enough to complete most purging jobs. It is achieved by using two 18V LXT Li-Ion batteries (BL1860B) as the power source, while increasing the vacuum level up to 3Pa for purging large air conditioning systems.
