In direct pressure nozzles, the fluid is broken up (atomized) into droplets by either impact on a surface or by the swrilling motion caused by passing the liquid through a shaped orifice. In both cases the energy required for the atomization comes from the potential energy of the fluid itself. Essentially the energy available for atomization is a function of fluid pressure.
In air atomising nozzles pressurized air (or other gas) is used to impact upon the fluid being sprayed. The impact of the gas causes the fluid to break apart into a fine spray. This means that the energy required for atomisation is no longer dependent on fluid pressure because of which very fine sprays can be produced at low fluid pressures. The allows for very fine, low volume sprays to be delivered.
Air Atomising Nozzles have many unique spray properties and specification which helps the designers to use in wide range of spraying applications.

Spray atomization involves creating a condition of high relative velocity between the liquid to be atomized and the surrounding air or gas. Typical atomizer nozzle types include:
• Electrostatic
• Impinging jet
• Windmill
• Whistle
• Ultrasonic
• Twin fluid. Twin-fluid atomizers include all nozzle types, and may involve one of the processes below :
Internal Mix – The gas and liquid are mixed within the body of the nozzle. It forms the finest atomization, which exits through one orifice. There is a direct relationship between the liquid and the air; any change in the air pressure affects the liquid flow. The full cone, hollow cone and flat spray patterns can be achieved using the internal mix method.
External Mix – The gas and liquid are mixed externally; this offers better control since there is no connection between the gas and liquid inlet lines. Viscous liquids can be sprayed using External mixtures. however, the atomization is not as fine as in the internal mix. Both full cone and flat spray patterns are achievable.
Air Atomizing Nozzles, Industrial Spray Nozzles
Air Atomizing nozzles are a precision spraying device that mixes air and liquid at a proportion targeted at a subject. Multiple air atomizing spray nozzles are available for a variety of purposes. In an Industrial setup, lubricating the moving components or parts is a...
Choosing the right air atomizing spray nozzle depends on your fluid type, droplet size, and spray pattern needs. Use:
1.Internal mix nozzles for fine misting of low-viscosity fluids
2.External mix nozzles for high-viscosity liquids with independent control
3.Adjustable nozzles for flexible spray angles and flow rates
Ideal for coating, humidification, dust suppression, and cooling, our nozzles are available in SS316, brass, and custom materials.
