When it comes to wall art for a manufacturing facility, it's important to consider both aesthetics and functionality. Here are a few types of wall art that could work well:

1. Safety Posters: Safety should be a top priority in any manufacturing facility, and displaying safety posters can help remind employees of important safety procedures and precautions. These posters can be both informative and decorative, and they can help create a culture of safety within the workplace.

2. Motivational Posters: Motivational posters can help inspire employees and boost morale. They can be especially effective in areas where employees may be performing repetitive or monotonous tasks.

3. Company Mission Statement or Values: Displaying the company mission statement or values on the walls can help reinforce the organization's goals and values. It can also help create a sense of unity and purpose among employees.

4. Product Images: Displaying images of the products that are manufactured in the facility can help create a sense of pride among employees. It can also serve as a reminder of the end goal of their work.

5. Industrial or Technical Artwork: Artwork that incorporates industrial or technical themes can be a great fit for a manufacturing facility. This type of art can celebrate the machinery and technology that is used in the facility and can serve as a tribute to the workers who operate it.

Ultimately, the type of wall art that is best for a manufacturing facility will depend on the specific needs and culture of the organization.
