DJ Automatic Air Atomizing Nozzle

DJ Automatic Air Atomizing Nozzle is a high-performance industrial spray solution that delivers precise, efficient, and repeatable atomization. Featuring an advanced internal air-driven actuator, the nozzle enables automatic on-off operation at high frequencies of up to 180 cycles per minute, ensuring accurate control of liquid flow in intermittent spraying applications. During operation, only the liquid supply is shut off while air continues to flow, maintaining consistent atomization quality and reducing response delay.

This nozzle supports multiple liquid supply methods, including siphon feed, gravity feed, and pressure feed, providing flexibility for different system configurations and installation conditions. Its adaptable structure allows easy integration into various industrial processes without complex adjustments.

Manufactured to strict quality standards, each component is precision-engineered to ensure stable performance and long service life. Nozzle body is available in nickel-plated brass or stainless steel, while critical internal parts such as needle valve, fluid cap, and spring are made of stainless steel to enhance durability and corrosion resistance in demanding environments.

With multiple connection options, including 1/8″ and 1/4″ NPT or BSPT threads, and adjustable spray angles typically ranging from 10° to 110°, nozzle offers versatile spray coverage for a wide range of applications. It is widely used in lubrication, humidification, coating, cooling, and other precision spraying processes where consistency and automation are essential.

Overall, DJ Automatic Air Atomizing Nozzle combines reliable automation, precise control, and flexible configuration, making it a dependable choice for modern industrial spraying systems.

Model Options

DJ Automatic Air Atomizing Nozzle is available in different configurations to meet various application requirements:

Standard Type (1/4DJ)
The 1/4DJ model features 1/4″ NPT or BSPT (female) air and liquid inlets, along with a 1/8″ NPT or BSPT (female) air-driven control port. It is typically used with low flow rate liquids and is suitable for general industrial spraying applications where stable and precise atomization is required.

Compact Type (1/8DJ)
The 1/8DJ nozzle is a compact automatic atomizing nozzle designed for space-limited installations. It offers similar operating characteristics to the single air-line system, with both air and liquid inlets using 1/8″ NPT or BSPT (female) thread connections. This model is ideal for small-area spraying and applications requiring a more compact setup.

Single Air-Line Type
This configuration utilizes a single air supply line for both atomization and actuation. It allows synchronized control of air and liquid flow during the on-off cycle, ensuring consistent spray performance. The nozzle can operate at speeds of up to 180 cycles per minute, with a minimum required air pressure of 2 bar, making it suitable for high-frequency intermittent spraying applications.
