What are dry filter spray booths?

Any standard spray booth will be suitable for my bodyshop, right? Well… not necessarily. Depending on your production quantities, working speeds and bodyshop budgets, it will completely depend on which spray booth is most suitable to you — whether that be water wash spray booths, one with a dry filtration or some other alternatives.

Regardless of whether you are investing in new equipment, contemplating an upgrade or just want to gain a greater understanding of how appropriate your current setup is, read on to dive into what exactly dry filter spray booths are, and how they can differ from the alternatives.

The dry filtration process

Using filters in the dry filter spray booths, paint particles are captured and separated from the constant air stream and deposited through an extraction filter. Different filters are available and are specifically designed for different materials being sprayed. Due to this simple yet effective process, dry filtration can be utilised in various forms, from small stand alone dry filter spray booths to automatic application booths for robot, reciprocator or fixed guns.

Dry filtration might be one of the most common methods for keeping body shops contaminant-free, but it is most commonly used for low to medium production volumes. It is important to note, they can be rather ineffective for high-levels of production, especially as they require downtime for when filters need replacing.

How do they compare?

Comparably to water wash spray booths that utilise a water curtain (or scrubber section) to contain the paint and then transferring it into the collection chamber, dry spray booths can be a lot easier to manage. Water wash filtration requires regular cleaning of the sludge that can build up in the collection tank (leaving another process to add to the workshop maintenance programme), whereas dry spray booths are relatively low maintenance.

Sludge removal machines for water wash filtration can be installed to make the process easier, but it can make an already expensive spray booth alternative just that bit more costly. On the other hand, dry filtration booths are not only cheaper to maintain, but the initial set up costs are significantly lower than its water-using counterpart. Not to mention that they are easier to install, which is something that will drastically reduce engineer installation fees.

Why opt for Dry Filtration?

All of our dry filtration systems are designed from the ground up to perform highly energy-efficient operations. Not only is this a more sustainable approach to running your body shop, but it can dramatically reduce operation costs. Yet we never compromise on quality. Our dry filter spray booths are built with high-quality steel, providing you with durability and the reliability that you require for a smooth-running production line.
