3MX / 7MX Low Pressure Misting Spray Nozzles
3MX / 7MX Low Pressure Misting Spray Nozzles are multi-orifice hydraulic atomising nozzles designed to create a fine mist using hydraulic pressure alone.
The 3MX version uses three atomisers to deliver an approximate 90° coverage angle, while the 7MX version uses seven atomisers for a broader spray angle of around 150°.
Fine droplet sizes from 50 to 300 microns help support effective misting performance across fire protection applications.
Available in brass, AISI 303 and AISI 316, these nozzles offer a practical choice for systems that require reliable coverage, controlled droplet formation and flexible connection options.

More Information
3MX / 7MX Low Pressure Misting Spray Nozzles are engineered for applications that require fine atomisation, dependable coverage and consistent performance from a compact hydraulic nozzle design. As multi-orifice nozzles, they use hydraulic atomisers to generate a fine mist without relying on compressed air, making them well suited to systems where controlled droplet size and broad spray distribution are essential. Typical droplet sizes range from 50 to 300 microns, depending on operating pressure, giving designers the flexibility to match nozzle performance to the needs of the installation.
The key difference between the two versions is the spray coverage they provide. The 3MX model incorporates three atomisers and delivers a coverage angle of approximately 90°, making it a strong option for more focused protection zones. The 7MX model uses seven atomisers and achieves a wider coverage angle of around 150°, helping cover larger areas with fewer nozzles. This choice allows engineers and installers to select a nozzle format that fits the layout, hazard area and performance requirements of the system.
These nozzles are designed for active fire protection and are available in a wide range of flow factors and capacities, supporting different operating pressures and system demands. Performance options are shown across pressures from 5 to 80 bar, allowing the misting output to be tailored to the installation. Material choices include brass, AISI 303 and AISI 316 for compatibility with a range of environments and durability requirements. Connection sizes include 1/2" and 3/4" for 3MX models, with 7MX options available in 1/2", 3/4" and 1". Together, these features make the 3MX / 7MX range a reliable solution for engineered misting systems where coverage, atomisation quality and material choice all matter.
