A spray wall can be a crucial piece of equipment even for a small workshop. Decisions regarding the purchase of a spray wall require an analysis of several key factors that impact both work efficiency and user comfort. With many available solutions, it’s worth considering which options are best suited for smaller workspaces. In this article, we will outline important considerations to help you make an informed decision and ensure optimal conditions for painting.
When selecting a spray wall, it’s essential to ensure that the technical specifications match the size of your workshop and the type of work performed there. In small workshops, where space is limited, it’s crucial that the equipment doesn’t take up too much room while still effectively fulfilling its functions.
One of the most important decisions workshop owners face is the type of air filtration. Both wet and dry spray walls are available on the market. While wet extraction is often considered more efficient, for smaller workshops, a dry spray wall is often the more practical choice. It takes up less space and is significantly cheaper to operate. This makes it an ideal option for workshops where painting is not performed on a large scale daily.
When purchasing a spray wall, it’s important to consider whether the equipment should include an explosion-proof fan, known as ATEX. This type of equipment is essential in workshops where paints containing potentially explosive substances are used. Such equipment is most commonly used in industrial settings but can also be beneficial for vehicle painting in smaller workshops.
The type of fan is another crucial factor to consider when choosing a spray wall. Depending on your needs, you can choose from axial, centrifugal, or roof fans. Each type has its advantages, but the most important aspect is ensuring the fan matches the intensity of use. In smaller workshops where painting is less frequent and typically shorter in duration, axial or roof fans may be sufficient. It’s also important to note that similar products can vary significantly in pressure capacity, so this should be carefully considered.
There are several additional features a spray wall should have. The design of such a system should include a supply air system to ensure proper air balance, preventing the intake of external contaminants and enhancing painting quality. Heat recovery systems (recovery) can reduce heating costs, especially during extended use of the spray wall.
It’s also essential to have an exhaust system that efficiently removes fumes outdoors, as well as acoustic dampers that reduce noise and improve working comfort in the workshop. However, in small workshops, these elements don’t need to be at the highest level of sophistication since painting is likely only a part of the workshop’s overall activities.
