If you’ve spent any time looking through Paint Booths reviews, you’ll have noticed that there’s 2 different styles of booth to choose from, the dry filter and the water wash booth. Knowing which to choose can be difficult, so here’s some tips.
What’s the difference between the two?
Dry filter booths work with paper filters, or a similar synthetic material, in order to trap the solid waste generated by the coating. In a water wash booth, this job is done by a curtain of water in order to flush the waste product through to the waste reservoir. Do bear in mind that it’s only the solid waste generated that will be trapped like this- the solvents in the solution will evaporate off.
If you’re a pat-time or first time paint booth buyer, you’ll probably be tempted to go with a dry filter booth, as they are often far more economical. While they can be an excellent choice, be aware that there is only a certain amount of solid waste that can be trapped before the booth flow is impacted. At the point this occurs, production will be stopped for the length of time it takes to change and replace the filters. What filter type you’ve chosen will have a profound impact on the load time, and you are always advised to spend some time with paint booth reviews to help you choose a material that will work well for your purposes and needs.
What else affects the filter change time on a dry filter booth?
There’s quite a few other factors which will affect the load time of the filter, ranging from the efficiency of the spray gun itself- a high efficiency gun will ensure that more of the paint reaches the painted surface and less waste is generated- through to the atomization air pressure of the gun. Contrary to gut instinct, an over-atomized fluid will cause a drier spray, and the drier the spray the more easily it will be drawn into the filters rather than the project. Likewise, if fluid is being over-pressurized, a faster filter lading time will be needed. Lastly, the air flow through the booth- the factor that effects how much material is drawn away- will also have a profound impact on the filter change times. By controlling for these factors, you can significantly [and favorably] impact the length of time the booth spends offline. It will also have a positive impact on the amount of coating used in each session by cutting down on waste.
However, if you are a professional, and even some semi-professional, high output booth user, you may wish to consider using a water wash booth instead. If you reach a point at which the down time for filter replacement is costing you more than the installation and maintenance costs on the water wash booth would, it’s definitely time to reconsider.
All in all, whether you opt for a dry filter or water wash booth as your choice, there’s a lot to be gained from spending some time with paint booth reviews to ensure your purpose fit’s your needs and your budget.
