The ViscoMist 176 Series offers independent regulation of both atomising air and fan air, which provides the user with infinite control over the viscous fluid’s spray pattern and droplet size. The ViscoMist nozzle features a standard ‘Liquid Shut-Off / Clean-Out Needle’ function. This design element activates and deactivates the liquid supply, while simultaneously removing excess fluid from the Fluid Nozzle preventing clogging. This feature is especially vital when the viscous liquids are being applied in continuous process environments.
The modular design of the ViscoMist allows maximum flexibility to meet the exact spray requirements. Interchangeable air caps and various flow capacities are available to suit virtually any spraying application needs.
Increased hygienic requirements led to an improved smooth external nozzle design. The new design decreases the cleaning time for the body of the nozzle.
Description of inlet ports and their symbols
The ViscoMist has three Nozzle Body styles available. For all styles, stamped next to each inlet port on the nozzle is one or more letters representing the spray aspect(s) that particular port controls. These spray aspects and the letter representing each are as follows:
Atomising Air (A)
The Atomising Air Port influences the atomisation of the liquid into either small or large droplet sizes, simultaneously affecting spray distribution in the center of the spray pattern. To achieve finer liquid atomisation, increase the atomising air pressure.
Fan Air (F)
The Fan Air Port flattens the atomised liquid giving it a flat fan spray distribution. With the appropriate nozzle body configuration, this distribution can be adjusted independently to control the liquid spray width. To achieve a wider spray distribution, increase the fan air pressure.
The liquid flow rate is directly proportional to the liquid pressure rate. Subsequently, the higher the liquid pressure rate is, the higher the liquid flow rate will be. The liquid “On” or “Off” cycle is dependent on the Piston controlled Signal Air supply.
Signal Air (P)
Air supplied to this port actuates a piston located within the nozzle to retract or extend the Clean-Out/Liquid Shut-Off Needle. Retracting the needle allows the liquid to flow from the nozzle. A minimum of 40 psi air pressure to this port is required to operate the nozzle.
