Benefits and Types of Spray Paint Booths
While they used to be exclusively about auto shops, spray paint booths have now expanded into many other applications. This technology has proven its usefulness in various industrial settings now involving anywhere from tiny circuit boards to massive equipment.
Apart from giving these products a superior finish, spray paint booths also provide workers a safe environment as they are compliant with the standards set by safety organizations like the OSHA (Occupational Safety and Health Administration).
Types of Spray Booths
As expected from the manufacturing business, you will find a spray paint booth that is built for your specific application. There are models made for plastic, automobiles, furniture and more.
Here are the main types of spray booths you will find nowadays:
These models have a rear exhaust, a ceiling and two sidewalls. Air flows right through the front and leaves from the exhaust at the back. Open booths are typically used for woodwork and for furniture finishes. These boots are also common sights at auto facilities, including repair centers and manufacturing facilities.
This type of spray booth is enclosed, and exhausts as much air as it draws in. In colder environments, temperature control and air purity are maintained with the use of an air makeup system or heater. This method is popularly used for manufacturing and refinishing automobiles and electronic devices, in which the overall finish quality is significantly affected by the environment’s cleanliness.
Non-pressurized booths draw air from the building and expels it into the same using a set of filters. In some environments, a heated air makeup unit is a requirement. There are plenty of industries that use non-pressurized booths, including metalwork, fiberglass and car manufacturing.
Paint Booth Configurations
The airflow configurations of pressurized and non-pressurized paint booths can vary widely, and each one comes with its own advantages and setbacks.
In cross flow booths, air moves from front to back and side to side.
Downdraft booths have air coming in from the ceiling down to the floor. You will find several styles with this configuration, with the “pit” style (the exhaust system includes an excavated pit and tunnel) being the most common.
In semi-downdraft booths, air comes in from top to rear, while in side downdraft booths, it flows in from the ceiling going to the sidewalls where the exhaust filters are.
All booths are made for certain applications, depending on the needs of the user. When finish quality is vital, for example, the best options are side downdraft and downdraft booths.
When there is a need to control cost, cross draft and semi-downdraft are recommended. Finally, for applications where space is at a premium, cross draft is the most popular option.
