Accudraft TX™ truck paint booths are engineered according to your specific needs. Large size cabins with shadowless lighting design allow you to paint trucks and large equipment in a controlled environment. Heated makeup air can be added for better application temperatures and heated cure cycle allows you to paint more trucks per day.
Truck paint booths are available in a multitude of configurations. Each one has advantages to performance and also some advantages to installation in a truck finishing facility. Most truck paint booths are large and therefore require a lot space if the truck booth is installed indoors. In some instances outdoor truck paint booths can save a lot of valuable space inside a truck repair facility.
There are four major configurations for truck paint booths. Crossflow, Semi Downdraft, Side Downdraft, and Downdraft. Each can have any number of features and are available as heated or non heated truck paint booths. The performance features and layout options for a truck paint booth are generally the same. What changes between the different configurations of truck booths are generally two specific things; draft pattern, and the layout/space required.
The most popular type of truck paint booth on the market is the crossflow truck paint booth. Crossflow truck booths are very popular for two reasons. One is cost since it is generally the lowest when it comes to types of truck paint booths. The other is space, as it is one of the smallest footprint truck paint booths you can find.
The draft pattern in a crossflow draws the air along the length of the cabin from either front to back or back to front (also sometimes referred to as a “reverse flow” truck paint booth or “reverse crossflow” truck booth). This draft pattern makes the crossflow truck paint booth more economic because there is less airflow required. The cross section of the area where air is flowing is relatively small when compared to side downdraft or downdraft truck paint booths and thus the paint booth exhaust fans and paint booth air makeup can be smaller and less costly. The cost advantage makes a crossflow one of the most popular types of truck paint booths on the market

Another reason why crossflow truck paint booths are one of the most widely used paint booths in the truck refinish industry is that the dimensions of the crossflow truck booth is relatively small. There are no external ducts on the sides like that of a side downdraft truck paint booth. The exhaust fans are usually also above the truck paint booth cabin which keeps it off the ground and out of your way. The truck booth air makeup unit can be floor mounted right next to the booth cabin but also can be suspended or supported above the truck paint booth or can be installed on the roof of the building. Rooftop paint booth air makeup units are very versatile and can make a crossflow truck paint booth take up little to no extra room outside the booth cabin footprint.
Ceiling height is another advantage to crossflow truck paint booths. The crossflow truck paint booth delivers air to the paint booth cabin either through filtered front doors or through supply air columns at one end of the truck booth cabin. This means that the crossflow truck paint booth needs no upper ceiling plenum to deliver air like all other types of truck paint booth. When a facility has a low ceiling or the height of the trucks being painted in the truck booth need all the room they can get, a crossflow truck paint booth can be designed to maximize ceiling height within the truck repair and refinish facility. Other types of truck paint booth would lose some ceiling height in the truck paint booth work space.
Semi downdraft truck paint booths are also extremely popular in the truck repair and refinish industry. Semi downdraft refers to the incoming air being delivered into an upper plenum above the truck paint booth ceiling. Semi downdraft is extremely popular mostly because the addition of heat is very easy if you were to purchase or install a non-heated truck paint booth and upgrade with a heated paint booth makeup air unit later on.
The draft pattern in a semi downdraft truck paint booth also draws the air along the length of the cabin like a crossflow. It can flow from either front to back or back to front (also sometimes referred to as a “reverse flow” truck paint booth or “reverse semi downdraft” truck booth). This draft pattern makes the semi downdraft truck paint booth more economic because the airflow required is less than other truck paint booth configurations such as downdraft or side downdraft. The cross section of the area where air is flowing is relatively small when compared to side downdraft or downdraft truck paint booths and thus the paint booth exhaust fans and paint booth air makeup can be smaller and less costly. What makes a semi downdraft paint booth different than a crossflow truck paint booth is that it’s generally a cleaner delivery of supply air and offers flexibility for the addition of heat in the future. A crossflow paint booth draws air in from filtered doors or through columns that may allow the introduction of contaminants or debris more so than the upper plenum of a semi downdraft paint booth. The upper plenum is generally cleaner and free from debris and contaminants that are present at ground level where all the work is done inside and outside the truck paint booth.

Semi downdraft truck paint booths are a great system that make good use of floor space and offer lots of installation flexibility, but the semi downdraft has an upper plenum, so the ceiling height of the booth may be a concern if the truck finishing facility has a ceiling height close to the height of the trucks it is looking to paint. Semi downdraft paint booths offer better flexibility in terms of the addition of heat, draft pattern, and cleanliness which is slightly better than that of a crossflow generally speaking. What is most important to decide is if your needs include heat now or in the future and if the ceiling height in your shop will allow for an upper plenum on the truck paint booth you are looking to install.
Side draft truck paint booths are engineered to provide better airflow and cleanliness while still keeping the installation above ground. This is a big time and money saver when looking at the project of installing a truck paint booth in any facility. No concrete work is a major plus.
A side draft truck paint booth introduces air into the upper plenum above the truck paint booth’s interior ceiling and exhausts the air through plenums attached to the bottom of the side walls. The resulting draft pattern is very close to that of a downdraft truck paint booth. One major advantage to a side downdraft paint booth is that the side down truck booth does not need concrete pits to draw the air out of the booth. Concrete work can be time consuming and expensive. The equipment costs a bit more usually since it is the truck paint booth configuration with the most materials involved (a full upper plenum that runs the entire length of the truck paint booth and ducts on the left and right that run the entire length of the truck booth) but the overall project costs and downtime can be much less since there is no concrete work required and the installation of a side downdraft truck paint booth is done completely above grade on the facility’s existing floor.
Layout/ Will it Fit?
Side draft truck paint booths require a wider footprint than most other paint booths due to the exhaust plenums present on the bottom of the side walls. Each side of the truck paint booth will usually have a duct anywhere from 24 inches to 48 inches wide depending on the size of the truck paint booth and the airflow required. Side draft truck paint booth exhaust fans are usually contained within the footprint of these ducts, or, if they are larger than the duct, are normally set high above the truck paint booth cabin. Side draft truck paint booths need to have an upper ceiling plenum in order to deliver air all along the length of the paint booth work space. Non-heated side draft truck paint booths can be designed without a plenum and just have filters separating the shop from the interior of the paint booth. This would only be possible in a non-heated application and would require building a plenum above the truck paint booth if heat was ever added to the paint booth in the future.
Downdraft truck paint booths are engineered to provide the best airflow pattern and cleanliness available in the truck paint booth group. Airflow is directed under the truck being painted and under the painter.
A downdraft truck paint booth introduces air into the upper plenum above the truck paint booth’s interior ceiling and exhausts the air through a pit or pits in the floor. The resulting draft pattern is a consistent envelope of airflow around the truck being painted. Downdraft truck paint booths create a very clean and even draft that removes paint overspray away from the truck being painted and away from the painter no matter where the painter is working. The draft pulls the overspray down and away, keeping things clean and keeping the environment healthy for the painter or painters if there are multiple operators.
Layout/ Will it Fit?
Downdraft truck paint booths have a relatively small footprint since there are no external ducts or fans to the sides. Paint booth air makeup units can be installed next to the truck paint booth cabin or away from it or even outdoors to help save space. Truck booth makeup air units can also be installed above the truck paint booth or on the roof of the building.
Light fixtures are either outside or inside accessible, which allow for flexibility for service and maintenance. Outside access light fixtures mean that the back of the fixture is removable to change bulbs or service the ballast if standard fluorescent bulbs are being used. With today’s LED light bulbs for truck paint booths, fluorescent lighting is becoming a thing of the past. Inside accessible light fixtures for truck paint booths are also available so that the fixture is serviceable from the inside. Inside accessible truck paint booth light fixtures cost a bit more than the outside accessible fixtures since they must be built differently to meet code. They will be exposed to paint overspray present inside the truck paint booth and cannot have any exposed parts. They must be tested and certified to carry a special rating for class 1 division 2 hazardous environments. Inside access light fixtures in a truck paint booth have several advantages. They are much more easily serviceable since they can be serviced from inside the truck paint booth. In order to service outside access fixtures on a truck paint booth, sometimes you may need to get on a ladder or even rent a man lift or lifting equipment. Another advantage is the layout of the truck paint booth inside a facility. If a truck paint booth has outside accessible light fixtures, it cannot be pinned up against a building wall. Space must be allowed to provide service (usually a minimum of 3 feet, sometimes 5 feet) and this can take a lot of valuable space away from the truck repair and refinish floor space in the building. Inside accessible light fixtures on a truck paint booth allow the truck booth to be installed against a wall, saving this space. All fixtures are accessible and serviceable from inside the truck paint booth so this is a non-issue.
Dual skin insulated truck paint booths typically use inside access paint booth light fixtures only. The nature of the insulated panel’s construction and thickness of the walls makes this the best option and most manufacturers include inside access fixtures on an insulated truck paint booth. Due to this, insulated truck paint booths can typically be installed adjacent to a building wall. Egress would be the only thing to consider when installing a truck paint booth next to a building wall. Personnel access doors in a paint booth must be present at certain intervals and if there is a path to an exit that is too long, another exit door must be provided. If a truck paint booth is against a building wall, an access or exit door to the truck booth may need to be provided and a matching building door or walkway across from this door would need to be provided.
A double wall insulated truck booth or dual skin truck paint booth is a truck paint booth that has a cabin constructed of insulated panels with two “skins” referring to the two sheets of steel (interior and exterior). Insulation is a non-flammable rock or mineral wool that must be approved and certified for use in the construction of the paint booth. The truck paint booth must meet NFPA 33 standards and many others. Dual skin truck paint booths are insulated in order to keep the heat inside the truck paint booth for several reasons. Keeping the heat inside the truck paint booth makes it much more energy efficient and it also keeps the shop space around the outside of the truck booth cooler. In the summer months, especially in warm climates, the technicians that may be working near or next to the truck paint booth will be exposed to hot temperatures radiating from the truck paint booth, making it very uncomfortable. Outdoor truck paint booths do not have this issue, but since the walls of the paint booth will be exposed to the outdoor temperatures, outdoor truck paint booths should be insulated to maximize energy efficiency.
Heat is a major decision when looking to install a truck paint booth. The addition of heat will allow for more control over application temperatures and proper adhesion of the coating being sprayed onto the truck or truck part. Incorrect temperatures that are either too hot or too cold can make a new truck paint coating fail either immediately or over time. In the case of too much heat, the typical culprit is the sun if a facility is painting trucks outside without a paint booth. The first step would be to find shade, but in some cases this may not be possible. Other problems may exist with painting trucks outdoors such as contamination and dirt, bad weather, or problems with the EPA and air quality authorities in the area. In any case the use of a listed and approved truck paint booth is recommended. If the spray are is too cold, the use of a heated truck paint booth is recommended. Getting the truck or substrate up to the proper application temperature is critical to the adhesion and performance of the paint or coating being sprayed. Getting the truck up to temperature can also take a very long time if the truck paint booth does not have its own heated air makeup unit. Trucks have very thick substrates such as steel that take a long time to warm up if the truck is left indoors to gain some temperature. A heated truck paint booth will allow the user to heat the truck quickly and be ready to paint in a fraction of the time.
With a non heated truck paint booth running inside a truck finishing facility, local mechanical or building code require that air replacement or “makeup air” systems be installed to replace the large amount of air being exhausted from the building. If a large system such as a truck paint booth is allowed to pull air out of a building unchecked, there could be other dangers created in the building due to the lack of pressure. If the authorities require the installation of a makeup air unit in order for you to install a truck paint booth, it always makes sense to budget that expense as part of a heated truck paint booth and not a non-heated truck paint booth plus a makeup air unit for the building. In effect, you would be installing a makeup air system on the building to condition the air and then the truck paint booth would simply be exhausting all the air that was just conditioned. A heated truck paint booth will cost about the same as a non heated paint booth plus a building makeup air system and will be much more energy efficient. The paint booth will be a closed loop now and the paint booth heat unit would include many extended capabilities such as a cure or “bake mode” on the truck paint booth system. For roughly the same dollar investment, you can control how much energy is used and produce more out of the paint booth system.

Heat reclaim technology is an important feature on any truck paint booth and especially in cold climates. When conditioning a large volume of air such as that inside a truck paint booth, a lot of energy is required. High cfm is rushing through the cabin to provide airflow and that air is normally heated to a proper spraying temperature such as 75 degree Fahrenheit. During the spray or working phase of the finishing process, 100% of this heated air is being passed through the truck paint booth and is being exhausted since there may be harmful or hazardous materials present. A truck paint booth with a heat reclaim system will actually take back or “reclaim” a significant portion of this otherwise wasted heat and temper the incoming intake air with this energy. When exchanging this energy, the cold intake air becomes warmer and thus needs less energy from the heat unit to get the 75 degrees desired in the spray phase. Likewise during the cure cycle or “bake” phase, the 20% intake air being brought in (assuming the truck paint booth has a true 80/20 heat recycle) is actually gaining heat from the 20% hot air that is being exhausted, making the heat unit and burner use less fuel to get to bake temperatures.
For example, a 20,000 CFM heat reclaim system on a truck paint booth operating in the spray cycle at 75 degrees Fahrenheit will produce approximately 45 degree intake air if the outside air temperature is 23 degrees. In this case, the heat reclaim unit creates twenty degrees of temperature rise from energy that is traditionally wasted. The big savings comes when you look at a truck paint booth in a real world application. Some truck paint booths use forty to sixty thousand cfm. Imagine doubling or tripling these savings and then couple that with the fact that this is going on every hour of every day for the life of the equipment. The colder the climate, the more the case for heat reclaim.
