The Crescent Tank Vacuum Tank is completely flat inside and out. It has no baffles, allowing it to be emptied completely to avoid internal corrosion. With the included pump at specified cfm, unnecessary fatigue of the structure is eliminated and the life of the tank is prolonged. It is made from ¼-inch steel, making it structurally strong. The workstation is designed for the portable restroom industry. The lift gate rail width allows units to fit, and multiple lift gate decks and rail options are available. It carries up to 10 portables based on the model, and the weight capacity is the same as a flatbed truck. Freshwater is held inside the ½-inch-thick poly tank externally to avoid internal wastewater contamination. It can be installed by Crescent Tank on any chassis within the specifications required for each model based on axle ratings and maximum load capacity, or can be installed by the purchaser. 585/657-4104; www.crescenttank.com.
