Iwata Bellaria W400 Review 

Iwata is one of those names that is synonymous with high performance paint sprayers. The company offers a wide range of options, and that makes it possible for them to provide you with something for every type of paint job you might have.  

What is the Iwata Bellaria Good At? 

Most Iwata spray guns are perfect for varnishes, large spray paint projects (like murals), applying a base coat, or clear. The Iwata Bellaria is a perfect choice for base and clear coats. It lays clear coats and paints with precision.  Because it’s gravity feed, it lays down paint soft and smooth.  

Spray guns like the Iwata W400 Bellaria work well with water based paint and dense paints and are often recommended by professional painters. 

While pricier than some of its competitors, you get a great gun with top notch performance for the price. Even though this is a great spray gun, there are still pros and cons that should be considered.

How much does the Anest Iwata Bellaria Weigh? 

A lightweight, compact build and weight distribution is so important in a spray gun. 

The body of the Bellaria weighs about 0.84 pounds and is about 15% lighter than the older model.  And, due to the cup and gun design, offers an improved weight distribution that makes this a comfortable sprayer to use for long projects.   

These overall improvements and attention to detail make the Iwata Bellaria easier to use for large projects because you won’t suffer from wrist fatigue or an unbalanced gun. 

Air Caps and Valves 

Anest also uses a new technology for its air caps that helps with enhancing the Iwata Bellaria W400’s CFM and power. Another great included feature is an extra valve that helps to reduce color fade.

It also comes in a wide variety of fluid nozzle sizes (this one review here is 1.3mm), so you can buy it in the perfect tip size for your project. 

The ​Iwata W400 Bellaria is durable, and that’s because of Iwata’s dedication to crafting their tools with only the highest-grade materials. This spray gun is versatile and will remain that way for years to come if taken care of properly. 

What You Won’t Like about the Iwata Bellaria 

If you’re in the US, the Anest Iwata Bellaria W400 isn’t compliant with all standards. This makes it an option that you should consider with care.

However, if you don’t have to comply with any standard (for instance, if you are just a hobbyist), then this gun is still a great choice. 

Also, it seems to have higher overspray that some other models in the same category with a paint transfer rate of only 65%.
