STAINLESS STEEL PRESSURE TANKS

What are Iwata Stainless Steel Pressure Tanks and why choose them

Iwata stainless steel pressure tanks are robust containers designed to store and feed paints, coatings, release agents and similar liquids under controlled pressure. They are typically used together with spray guns and automatic coating systems to ensure a stable, pulsation-free material supply. The stainless steel construction offers high resistance to corrosion and makes the tanks suitable for both solvent-based and water-based products, as stated by the manufacturer for its stainless steel pressure tank range.

This description is based on general information from Iwata/Anest Iwata about their stainless steel pressure tank lines (such as PET and COT series) and may not match every specific model. Individual capacities, pressures and fittings must be checked per model, as not all data could be fully verified for each tank size.

Main features

• Stainless steel construction: Designed to provide high resistance to rust and chemical attack, making the tanks suitable for a wide variety of industrial liquids, including paints and mold release agents.
• Corrosion-resistant interior finish: Many Iwata stainless pressure tanks feature a polished or mirror-finished inner surface to reduce material adhesion and simplify cleaning.
• Range of capacities: Available in multiple tank volumes (for example, around 10–80 L in typical paint pressure tank catalogues) so that the user can choose the size that best aligns with consumption and installation space. Exact sizes vary by model and are not fully verified here.
• Designed for pressurized feeding: Developed specifically for use as pressure pots, supplying coating materials to manual or automatic spray guns in a stable and controlled way.
• Compatibility with different viscosities: Certain stainless steel pressure tank models are indicated for liquids up to approximately 3,000 cps (data example from a COT stainless series), covering many common industrial paints and release agents.
• Options for agitation: Depending on the model, the range includes versions with manual or pneumatic agitation to keep the material homogeneous during operation; availability of specific agitator types must be checked for each tank.
• Integrated regulation and safety equipment: Typical Iwata pressure tanks are supplied with pressure regulators and safety devices appropriate for their operating range (individual configurations vary by model and are not fully detailed here).
• Designed for industrial use: Intended for continuous or semi-continuous operation in industrial coating lines, offering stable supply and durability under demanding conditions.

Technical specifications (general, non-model-specific)

The following technical information is a generic, non-exhaustive summary derived from several Iwata stainless steel pressure tank catalogues and may not be valid for every specific tank. All values are indicative and not fully verified for a particular model.

• Construction material (tank body): Stainless steel.
• Typical tank capacities (examples from catalogues): Approximately 10 L, 20 L, 40 L, 60 L, 80 L and similar, depending on series and model.
• Typical usable capacity range: The catalogues usually specify a normal upper and lower filling limit within the nominal volume (for example, 8.4–2.6 L for a 10 L tank in one general-purpose series). Exact values vary by model and are not confirmed here.
• Maximum operating pressure (example values): Around 0.34–0.40 MPa (approximately 3.4–4.0 bar) for some stainless pressure pot types. Not all stainless tanks use exactly these limits.
• Recommended operating temperature range (example): Approximately 5 to 40 °C in several pressure tank lines.
• Typical connections (vary by model and thread standard):
  • Air inlet: often around G1/4 (BSP) in many catalogues.
  • Fluid outlet: frequently around G3/8 with one or more outlets, depending on configuration.
• Inner surface finish: Many stainless tanks indicate a mirror-polished interior to minimize residue adherence and improve cleanability.
• Compatible media: Paints, release agents and other liquids used in coating processes, within the specified viscosity range and chemical compatibility of stainless steel and seals.

Applications and use cases

• Industrial painting and coating: Feeding manual or automatic spray guns in production lines for metals, plastics, wood, automotive parts and general industrial components.
• Mold release agent application: Supplying mold release fluids in molding and casting processes, where stainless steel is beneficial for cleanability and chemical resistance.
• Water-based and solvent-based systems: Stainless construction makes these tanks particularly suitable for aggressive or water-based formulations, reducing risk of corrosion and contamination compared to standard carbon steel.
• Multi-gun installations: Models with multiple fluid outlets can be used to feed more than one spray gun from the same tank (dependant on the exact tank configuration and distribution system).
• Situations requiring easy cleaning: The polished stainless interior and, in some cases, removable liners reduce cleaning time and solvent consumption, which is helpful for frequent color or product changes.

FAQ – Iwata Stainless Steel Pressure Tanks

1. Are all Iwata stainless steel pressure tanks suitable for both solvent and water-based products?

Many stainless steel tank versions are described as suitable for both solvent and water-based materials thanks to their corrosion resistance, but compatibility can depend on seals, gaskets and specific chemical formulations. Always verify compatibility for the exact model and product.

2. What maximum operating pressure do these tanks usually support?

Several catalogues indicate maximum operating pressures around 0.34–0.40 MPa (about 3.4–4.0 bar) for pressure pots, but this can vary between models and series. Exact allowable pressure must be checked for each individual tank.

3. Do all tanks include an agitator?

No. The range typically offers models without agitation as well as versions with manual or pneumatic agitators. Presence and type of agitator depend on the specific model and are not guaranteed for every tank.

4. Are stainless steel pressure tanks supplied with regulators and safety valves?

Many Iwata pressure pots are sold with integrated pressure regulation and safety devices, but the exact configuration (single/double regulation, type of safety valve, etc.) differs among models. The specific tank documentation should be checked to confirm what is included.

5. Can a single tank supply more than one spray gun?

Some pressure tanks, especially those with more than one fluid outlet, can be set up to feed multiple spray guns through an appropriate distribution system. However, capacity, outlet configuration and process requirements must be considered case by case.

6. What liquid viscosities can typically be handled?

As an example, certain stainless pressure tanks mentioned in Iwata literature are intended for liquids up to roughly 3,000 cps, which covers many standard coatings and mold release agents. For higher viscosities, pump-assisted systems are often preferred.

7. Are these tanks suitable for food, pharmaceutical or hygienic applications?

The tanks described here are designed mainly for industrial coatings and similar media. Suitability for food or pharmaceutical use is not stated in the consulted product information and must not be assumed without explicit confirmation for a specific model.

8. How often do the tanks need maintenance?

Maintenance intervals depend on usage intensity, type of product handled and local regulations. Regular checks of seals, fittings, regulators and safety valves, as well as thorough cleaning of the interior, are recommended for any pressure tank system.

9. Are all the dimensions and capacities mentioned in this description exact for every model?

No. The data shown here are generic examples taken from several Iwata catalogues and should be considered indicative only. Exact values may differ significantly depending on the specific tank reference.

Section 14 – Transport information

The available manufacturer information focuses on product functionality and does not provide detailed, model-specific transport data. In general, stainless steel pressure tanks should be transported depressurized, securely fixed to avoid movement or impacts, and protected from contamination and mechanical damage. Any transport of tanks containing residual product or under pressure must follow the applicable transport regulations for pressurized equipment and the safety requirements of the material inside. Concrete legal classifications, labelling and documentation requirements cannot be confirmed with the consulted data.

Section 8 – Individual protection measures

The stainless steel pressure tanks themselves do not define specific personal protective equipment; PPE requirements are dictated mainly by the products being handled (paints, coatings, release agents, solvents, etc.) and by the pressurized nature of the system. In industrial coating environments, common individual protection measures typically include at least safety glasses or a face shield, suitable chemical-resistant gloves, protective clothing and, when spraying or handling volatile or hazardous substances, appropriate respiratory protection. This description is generic and not based on a specific Iwata safety sheet, so exact PPE requirements must be set according to the chemical safety documentation and local regulations for each application.
