Shops and production line related work need equipment that can easily automate tasks. These tasks may range from manufacturing, assembly to finishing. These are true to many companies that cater to automotive and other machinery and vehicle services. While these are more large scale, some are also useful in garage area small part production places.

One activity that has been automated is painting. Now, this may seem small and trivial but when vehicles are the subject of the topic, a whole new perspective is opened up. Not only is hand painting a large chunk of metal time consuming, it can also pose as a health hazard to the ones doing the job. Doing this manually also increases the chances of human error. This where paint spray booths come in handy.

Its purpose is not only to speed up the task but to make sure that the human error factor in doing the job is decreased if not eliminated. These booths come in different sizes and there are those that are designed to cater to even smaller parts. The principle behind the structure revolved around drafts and ventilation. It is important that harmful particles are separated to lessen health and fire hazards.

The vent and exhaust system integrated in the booth suck out the overspray and debris that can damage or make the finished surface imperfect. This also prevents any harmful effects on other equipment and those who work around the shop. The many ways that the design caters to this purpose varies and have given rise to different standard designs for spray booths.

The different structures and designs that the booth can come in matters depending on the customers need for it. Before purchasing or having one made, take into consideration vehicles and items are going to be painted with it. Size is the first thing to consider, then budget and lastly the design. There are four basic types that contractors are usually asked to make.

The reason why crossdrafts are not as expensive as other types is how it does not require as much materials to make. The air an ventilation just passes horizontally from entrance to exit, which is vent that gathers the overspray that also picks up dust. While this is the cheaper option, it tends to be the one that turns out as the most ineffective among all the choices available.

The ones that have the sides as ventilation areas are also popular. The benefits on the final product with this model is of higher quality based on results since the paint gets distributed more evenly than the previously mentioned type. The air is made sure to veer dust particles and other things that may stick to the finish away from the vehicle.

The ones where exhausts are located at the side, in relative to the object that needs to be painted are the more expensive of all four standard models . This is because there are more materials that is being used in its construction. The biggest advantage is how the overspray is being veered away from the object so it becomes unlikely that dirt and debris stick to the paint.

The semi down structure, while better than the crossdraft, still has its disadvantages. This is because the vent is located at the lower rear area. It does not cover the whole back part, unlike what you can see in portable crossdraft versions. It is more efficient in absorbing the debris in a cleaner manner but since the particle still needs to travel a substantial amount of space, there is still a higher likelihood that debris can get caught in the finish.
