The XAER enables effective spraying of viscous fluids at very fine atomization and low flow rates. The XAER air atomizing spray nozzle provides a full cone round spray pattern that is especially suited for liquids with a high viscosity (100+ cP). The round pattern XAER complements the existing XAEF nozzle, which produces a flat fan spray pattern. The BETE XAER nozzle operates with an external mix, which means the atomization of the fluid takes place outside the nozzle. As the XAER is an external mix, (as opposed to an internal mix), the flow rate is not dependent on the air pressure, which results in easier control. It is available for 1/8-inch and ¼-inch pipe sizes and can be specified in a choice of standard materials including nickel-plated brass, 303 or 316 stainless steel. The XAER can also be constructed from other materials to accommodate demanding conditions.
