Applications and use cases

The Iwata AZ3 HTE P.A.S. Concept is intended as a specialist spray gun for materials that are too thick or difficult for standard gravity guns or that you prefer not to run through pumps or pressure tanks. Typical applications, which may vary depending on nozzle size and coating manufacturer recommendations, include:

• High-viscosity primers and fillers where extra cup pressure helps maintain a stable flow and coverage.
• Thixotropic waterborne coatings applied in small to medium batches.
• Industrial maintenance and protective coatings requiring a robust gun and reliable atomization.
• Wood, metal and machinery components where heavy products or high-build layers are needed.
• Automotive and commercial vehicle refinishing for primers and specialty products, when allowed by the coating’s technical data sheet.

Suitability for a given product always depends on the coating manufacturer’s recommendations (nozzle size, pressure, and gun type). Before use, check the paint or coating technical data sheet to confirm compatibility with an HTE gravity gun with pressurized cup.

FAQ

Is the AZ3 HTE P.A.S. Concept suitable for waterborne coatings?

The gun is described in manufacturer catalogues as having stainless-steel fluid passages, which are generally compatible with many waterborne products. However, this information is not independently verified. Always confirm compatibility with both the official Iwata datasheet and the coating manufacturer’s recommendations.

Which nozzle size should I choose?

Nozzle selection depends on the viscosity and type of product. Smaller nozzles (for example, around 1.3 mm) are often used for thinner materials, while larger sizes (such as 1.8–2.0 mm) are generally chosen for heavier primers or high-build coatings. Follow the coating technical data sheet for the recommended nozzle and pressure range.

Do I need a powerful compressor to run this gun?

Catalog information suggests a moderate air consumption in the order of 190 l/min at around 2.5 bar, but this value is not verified. As a rule of thumb, ensure your compressor can continuously supply slightly more than the gun’s stated air consumption at the required pressure, and include a safety margin.

Can I use the AZ3 HTE P.A.S. for clear coats and basecoats?

The gun is primarily marketed as a high-viscosity and specialist application tool. While it may spray basecoats and clearcoats with the right setup, many users prefer dedicated finishing guns for those applications. Check the paint manufacturer’s guidelines and, if possible, perform test panels before using it on critical finishes.

Does the gun include the pressurized cup and mini regulator?

Standard kits described in Iwata catalogues usually include the gravity spray gun, a pressurized cup (around 600 ml), mini pressure regulator and basic accessories. However, configurations may vary by distributor and region. Always confirm the exact contents of the package with your supplier.

Is this product ATEX-certified?

Some Iwata spray guns have documentation mentioning suitability for use in hazardous zones, but this may depend on the exact model and region. There is no verified, specific ATEX statement here for the AZ3 HTE P.A.S. Concept. If ATEX certification is critical, request the relevant conformity documents or official datasheet from Iwata before purchase or installation.

How should I clean and maintain the gun?

In general, you should empty and depressurize the cup, flush with a compatible cleaning solvent, and clean the nozzle, needle, and air cap with appropriate tools and brushes. Do not use metal objects that can damage precision orifices. As procedures may differ by finish and product, always follow the official Iwata instruction manual and the cleaner manufacturer’s safety instructions.

Are all the technical values here guaranteed?

No. The numerical data provided (such as pressure, air consumption, and pattern width) come from publicly available manufacturer catalogues and are not independently verified. For critical projects and compliance requirements, rely exclusively on the latest official Iwata technical datasheet and user manual.

14. Transport information

This section summarizes general transport considerations for the spray gun itself, not for the coatings used with it. The information below is based on the typical characteristics of manual spray guns and has not been formally verified for this specific model.

• Dangerous goods classification: A manual gravity spray gun without paint in the cup is generally not classified as dangerous goods for land, sea or air transport. Classification can change if the gun or cup contains residual or uncured coating material.
• Packaging: Usually supplied in a protective carton box with internal supports and the pressurized cup and accessories packed separately or securely fixed (configuration may differ by supplier).
• Clean condition: Before shipping used equipment, ensure the cup and fluid passages are emptied and cleaned of flammable or hazardous residues according to local regulations.
• Regulatory compliance: If the gun has been used with hazardous coatings, transport requirements may be governed by the properties of those products (for example, ADR, IMDG, IATA). Always refer to the safety data sheet of the coating and local regulations.

For precise, legally binding transport information, especially in professional or international logistics, consult your company’s safety officer and the official documentation of both the spray gun and the materials used with it.
