A/b series metal nozzles feature a hollow cone spray pattern with a ring-shaped impact Area and spray angles of 51¡ã to 144¡ã. They produce small to medium sized drops at a wide range of flow rates and pressure. A/b metal nozzles are ideal choice for applications requiring good atomization of Liquilds at lower pressures or when quick heat transfer or effective airborne droplet Impingement is required. A/b metal nozzles have special whirlchamberthey feature large and unobstructed flow Passageswhich minimize or eliminate clogging. B metal nozzles have outer screw thread connection while a metal nozzles have Inner screw thread connection.
