Benefits and Types of Spray Paint Booths
Spray paint booths were once all about car shops, but several modern applications have since emerged. From massive industrial equipment to tiny circuit boards, this technology has now proven its worth in unexpected ways.
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
Like most other things in manufacturing, there is likely a spray paint booth that is designed for your unique needs. There are models made for plastic, automobiles, furniture and more.
Here are the types of spray booths you can find today:
These models have three parts: a ceiling, a rear exhaust plenum, and two sidewalls. Air flows right through the front and leaves from the exhaust at the back. Woodwork and furniture finishes are two common applications of open booths. These boots are also common sights at auto facilities, including repair centers and manufacturing facilities.
This is an enclosed type of spray booth, from which air leaves in the same volume as it comes in. A heater or air makeup system is used to maintain the right temperature and air purity in cool environments. Manufacturing and refinishing electronic devices and automobiles are common applications of pressurized spray booths, where cleanliness plays a huge part in the finish quality.
Non-pressurized booths draw air from the building and expels it into the same using a set of filters. Sometimes, a heater air makeup unit is required. A lot of industries, such as fiberglass, auto manufacturing and metalwork, use non-pressurized booths.
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.
Cross flow booths have air moving from the front to the 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.
Each booth is suitable for certain applications, depending on airflow needs and other requirements. When finish quality is vital, for example, the best options are side downdraft and downdraft booths.
If cost is an issue, semi-downdraft and cross draft are preferable. Finally, for applications where space is at a premium, cross draft is the most popular option.
