Types of Spray Paint Booths and Their Benefits

Spray paint booths used to be mainly about auto shops, but many modern applications have surfaced over time. This technology has proven its usefulness in various industrial settings now involving anywhere from tiny circuit boards to massive equipment.

Aside from providing an efficient way of finishing these products, spray paint booths also improve worker safety by ensuring their compliance with the OSHA (Occupational Safety and Health Administration), NFPA (National Fire Protection Agency) and other safety organizations.

Types of Spray Booths

Like most other things in manufacturing, there is likely a spray paint booth that is designed for your unique needs. Some models are made for motorcycles, boats, small plastics and so on.

Here are the key types of spray booths you will find today:

Open Face

These models have three parts: a ceiling, a rear exhaust plenum, and two sidewalls. Incoming air passes in front and leaves via the rear exhaust. 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.

Pressurized

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

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.

In downdraft booths, air comes from the ceiling going 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.

Semi-downdraft booths will have air coming in from ceiling to rear, while in side downdraft booths, air flows in from the ceiling and to exhaust filters on both sidewalls.

All booths are made for certain applications, depending on the needs of the user. For example, downdraft and side downdraft are best where finish quality is crucial.

If price is an issue, cross draft and semi-downdraft are more popularly used. Finally, for applications where space is at a premium, cross draft is the most popular option.
