Series 288A represents a complete line of vacuum breakers designed to prevent backsiphonage of contaminated water into a potable water supply. They feature a lightweight, durable "disc float" suitable for temperatures up to 180 deg F (82 deg C) which closes the atmospheric vent to prevent spilling under all rates of flow. Therefore, they are ideally recommended for low flow installations such as laboratory equipment which use such a small amount of water. They also contain a durable silicone disc which has high heat and water hammer shock resistance and assures tight seating with the lightest of seating contact. Full Size Orifice - Series 288A has a full-size orifice to assure pipe size capacity. Water passages are streamlined to provide high water flow with minimal pressure loss.
