Tank Evacuation Vapor Compressor

Save your expensive truck pump from damage when evacuating tanks in the field at an 8 to 15 GPM flow rate. Uses include on-site upgrading or downgrading size of storage in the field, and emptying cylinders or tanks in need of repair. This compressor transfers liquid by increasing vapor pressure in the tank being emptied and decreasing it in the tank being filled. The liquid can be moved into a bulk truck or another bulk tank.
