Non-pressurized Spray Booths for Vehicle Painting

Everyone knows that spray painting is the best choice for vehicles. This type of painting ensures that the whole body of the car is uniformly covered with paint. It also negates the traditional brush lines seen in painted automobiles. Most automobile spray painting businesses, however, do not realize that the location of the painting job will affect their job’s quality. When you spray paint a vehicle in the open, it is prone to the accumulation of contaminants that will cause uneven paint penetration.

As such, impact spray booths are essential to all automobile spray-painting ventures; they protect your application from contaminants. The booths are generally classified into non-pressurized, pressurized, and open.

Open spray booths have two side walls and a ceiling, allowing natural airflow through your booth. Pressurized spray booths will draw air from an inlet with filters and blow it through an exhaust fan. Non-pressurized booths, on the other hand, have their air supplied through a duct into the booth and directed through exhaust fans. Unlike other options, however, it allows control of the air that flows through your spray booth. Here are the types of non-pressurized impact spray booths:

Crossflow Booth

This is designed in a way that air will move through the booth from one side to the other. The concept behind this is to move the air past the vehicle being sprayed and remove solvents while averting the deposition of overspray onto the painted surface. Crossflow paint booths, however, usually have turbulent airflow, and it takes expertise to get flawless paint application in these circumstances.

Semi-downdraft Booth

In this option, air will travel from an input region in the booth’s ceiling to an exhaust location at one side of the booth. The air in this instance should “turn” in a particular direction to allow it to flow outside. Particles might accumulate at the site of “turning” of the air, and the “turning” might also cause turbulence and overspray deposition on painted surfaces.

Side-downdraft Booth

Here, air will flow in from an input region in the booth’s ceiling and out through exhausts located on two sides of the booth. The drawbacks of side-downdraft booths are the same as those found in semi-downdraft booths. If an expert spray painter handles the job, these drawbacks will hardly affect the final paint quality.

Downdraft Booth

In this option, air enters through the booth’s ceiling and leaves through the floor. Downdraft booths come in a range of style options, with pit-style and raised floor being the most common. A pit-style downdraft booth has an excavated tunnel and pit system that draw in air to the booth’s center. A basement or raised floor booth sucks in air through its floor’s grating and into a fabricated box that supports your entire booth structure.

With advancements in automobile coatings and paint-curing systems, the painting of vehicles has changed. As such, an impact spray booth is essential to the production of showroom-standard vehicle painting. Most suppliers will teach you how to use the booths to guarantee an exceptional job.
