Catalog on Pneumatic Spray Nozzles

Classification of Spray Droplet Size Although there are many opinions on the classification of spray droplet sizes, IKEUCHI, "The Fog Engineers", have classified them as below. Light Rain (0.3–1.0 mm) Semi-coarse atomization Fine Drizzle (100–300 μm) Semi-fine atomization Fine Fog (10–100 μm) Fine atomization Dry Fog (10 μm or less) Ultra-fine atomization 1 μm The above classification is based on the spray droplet size (spray droplet diameter) measured by the immersion sampling method. For comparison with other measuring methods, see the correlation of spray droplet diameter

What are Pneumatic Spray Nozzles? (Before selection) The pneumatic spray nozzle utilizes a high-velocity flow of compressed air and has the following features as compared with hydraulic spray nozzles. [Features] 1. Excellent atomizing performance Pneumatic spray nozzles are capable of producing fine atomization with a mean droplet diameter of 10 μm or less,*1 that are difficult with hydraulic spray nozzles. 2. Large turn-down ratio Pneumatic spray nozzles have large turn-down ratios of spray flow-rate*2 with little variation in droplet size and spray distribution, which makes them ideal for spray...

Technical Information on Pneumatic Spray Nozzles 1. Air-liquid mixing systems There are three air-liquid mixing systems for atomizing liquid. Internal mixing type Compressed air and liquid are mixed inside the nozzle. Generally, this type is excellent for atomizing liquid. This internal mixing type is further classified into three types. 1. Inner air type Compressed air flows in the center of the nozzle, while liquid flows along its circumference. This type provides an important benefit with a larger free passage diameter which minimizes clogging. Liquid flows in the center of the nozzle, while...

2. Liquid feeding system Two liquid feeding systems are available. One is the liquid pressure system (using pressurized liquid) and the other one is the liquid siphon system (using liquid sucked up by compressed air). Liquid pressure system Liquid siphon system Pressure gauge Pressure regulator Liquid strainer Spray capacity differs depending on liquid siphon height (H). 3. Spray pattern Spray pattern means the cross sectional shape of the spray. As illustrated, spray patterns are available in cone spray (hollow cone spray and full cone spray), flat spray, and liquid film-like spray. It is important...
