Applications and use cases

The WS-200 SP Split Nozzle is intended for professional users and fixed installations where stable pressure-feed supply and high productivity are required. Common applications include:

• Automotive refinishing and commercial vehicles: large panels, trucks, buses and industrial bodywork where a wide, even fan is needed.
• Industrial coating of large parts: machinery, fabricated structures, equipment housings and metal components.
• Wood and furniture finishing: lacquers and clear coats on large panels when a pressure tank or pump system is in place.
• Production lines: continuous coating processes that require constant material feed from diaphragm pumps or pressure tanks.
• High-solids and compliant coatings: applications where good atomization with reduced overspray is important, provided the product is compatible with the gun’s materials and specifications.

Always select the nozzle size, air pressure, hose diameters and coating type according to the manufacturer’s recommendations and the specific process requirements. When in doubt, consult the latest official documentation or technical service.

FAQ – Iwata WS-200 SP Split Nozzle

1. Is the WS-200 SP gravity-feed or pressure-feed?

The WS-200 SP is a pressure-feed spray gun. It is designed to work with external material supply systems such as pressure pots or diaphragm pumps, not with a gravity cup.

2. What is special about the Split Nozzle technology?

The Split Nozzle pre-atomizes the coating by using a specially designed air cap and nozzle geometry. This helps create finer droplets and a more uniform fan pattern, which can improve surface finish and transfer efficiency when correctly adjusted.

3. Which nozzle sizes are available?

Manufacturer documentation lists several nozzle sizes for the WS-200 SP series, typically from 0.8 mm up to around 1.8 mm, depending on the exact model. The availability of each size should be confirmed for the specific variant you intend to purchase.

4. Can I use solvent-based and waterborne paints?

The gun is generally designed with materials suitable for a broad range of industrial coatings. However, each paint or solvent must be checked for compatibility with aluminium and stainless steel parts as specified by the manufacturer. Avoid halogenated hydrocarbon solvents explicitly listed as unsuitable in the official manual.

5. What air pressure should I use?

Typical inlet pressures for WS-200 SP setups are around 0.25 MPa for many nozzle sizes, but this value is not universal. Always refer to the official nozzle/air cap chart for the exact model and adjust only within the permitted pressure range.

6. Is the WS-200 SP suitable for continuous industrial use?

Yes, it has been designed as a robust pressure spray gun for professional and industrial environments. Proper maintenance, cleaning and periodic checks of wear parts are essential to ensure consistent performance.

7. Does the gun comply with ATEX requirements?

According to the manufacturer’s manual, WS-200 series pressure spray guns comply with ATEX Directive 2014/34/EU and are suitable for Zones 1 and 2 when correctly grounded and installed. This information must always be verified against the latest official documentation for your region.

8. How should I clean and maintain the WS-200 SP?

In general, the gun should be flushed with a compatible cleaning solvent immediately after use, with the air cap and nozzle cleaned carefully to avoid damage. Only original spare parts and tools recommended by the manufacturer should be used. For detailed procedures, follow the official instruction manual of the WS-200 SP series.

9. Is this information fully verified?

No. The information provided here is compiled from publicly available manufacturer publications and general technical knowledge and may not cover all versions or the most recent updates. For complete and up-to-date data, always check the current official ANEST IWATA documentation before specifying, installing or using the product.

10. Can I use the WS-200 FT data for the WS-200 SP?

No. Although both belong to the WS-200 family, the WS-200 FT uses a different Flat Tip nozzle. Air pressures, flow rates and fan patterns differ from the WS-200 SP Split Nozzle versions and must not be interchanged without checking the correct charts.

Section 8 – Personal protective measures (from manufacturer safety information)

The official WS-200 series manual includes specific safety recommendations for personal protection during use. The following points summarize those instructions and should be considered minimum requirements:

• Use in a well-ventilated area, preferably in a spray booth, to avoid organic solvent exposure and reduce fire risk.
• Always wear appropriate protective gear, including safety glasses, suitable respiratory protection (mask), and chemical-resistant gloves.
• Use hearing protection (such as earplugs) when necessary, as noise levels can exceed 85 dB(A) depending on conditions.
• Do not attempt to stop leaks by hand. In case of leakage, stop the pump and relieve pressure to zero before any intervention.
• Ground the spray gun correctly using a conductive air hose with appropriate electrical resistance, to avoid static discharge and explosion hazards.
• Avoid unsuitable solvents listed by the manufacturer, as they may attack aluminium components and compromise safety.

These measures do not replace local regulations or site-specific safety procedures. Always follow your company’s health and safety rules and the full official instruction manual.
