When choosing a Truck Spray Booth you have a few choices to make. There are a multitude of available airflow configurations, each with their own benefits and performance criteria. These four major types of airflow design are explained below.

Size of the spray booth is another factor: due to their operational purpose they do inherently take up a considerable amount of workshop space. For this reason TRUFLOW has designed all of its floor mounted machinery to be as compact as possible without affecting performance. Of course for a bit more expense roof mounting machinery is an options. By placing machinery onto the roof you will save valuable floor space costs in the long term. Installed complete with a structural platform, safety handrails and service access ladder a TRUFLOW system provides full compliance and safe access.

Externally installed booths are also an option ( although typically the most expensive). TRUFLOW has provided external spray booth installations and these installations typically require weather protection covers as the spray booths themselves do not constitute a building ( they are plant and equipment) so planning is essential.

Regardless of the option you choose our experienced team is ready to help guide you through the entire process.



Crossflow Airflow Diagram

Crossflow Truck Booth

Crossflow Spray booths are a ideal solution for workshops looking to economically paint large equipment and trucks. Suitable for all types of re-finishing applications this range is an economical purchase in virtually unlimited sizes. A Crossflow spray booth is by far the most cost effective Truck Spray Booth and provides a solution which takes up the smallest factory footprint.

The cross flow is the most popular solution for Truck Spray Painting.

Key Benefits

  • Lowest cost option in Truck Booth range
  • Horizontal laminar airflow to .5 m/s Velocity
  • 4114.1:2003 Compliant & Certified
  • Clean, Filtered inlet and exhaust air
  • Negative Pressure – Contains Overspray
  • Modular Standard Sizes & Oversized Options available
  • Filtered entry doors
  • Enclosed Cabin with many lighting options.
Semi Downdraft Airflow Diagram

Semi Downdraft Truck Booth

The reference to Semi Downdraught comes from the “push and pull” design of this booth. The air is delivered via a supply fan partially through the ceiling of the booth. This air is filtered and provides the you with the option of heating as a standard feature or a future upgrade. For this reason the Semi Downdraught is a very popular choice in the Truck re-finishing sector where heating is required and a quality finish is desired in a very economical package. This system has been successfully used for painting trains, buses, coaches, wind towers, mining equipment and even aviation components.

Semi Downdraft is the most popular solution when requiring heating. 

Key Benefits

  • Standard Heating or Easy heating upgrade in the future.
  • Lowest footprint size for a heated, pressurised booth
  • Downdraft air at front plenum to Horizontal airflow at .5 m/s Velocity
  • 4114.1:2003 Compliant & Certified
  • Pressurised Environment with supply fan
  • Inlet air plenum provides cleaner environment when compared to crossflow.
  • Modular Standard Sizes & Oversized Options available
  • Enclosed Cabin with many lighting options.

On Floor Side/Rear Extraction Downdraft

This method of Downdrafting provides the majority of the benefits associated with Downdraft pit airflow while still maintaining an on floor installation ( No Concrete Works)

The airflow is introduced through the entire roof plenum mounted in the ceiling of the booth and is extracted low on either side wall or rear wall. This method is also commonly referred to as “full” based on the roof filters running the full length of the roof, not just partially like in a semi downdraught. These booths are custom designed and constitute a amalgamation in design principles.

On Floor Downdraught with side or rear extraction can be installed without concrete works. 

Key Benefits

  • Industry Benchmark as best airflow method without concrete works.
  • Ventilation through side walls (low) & no expensive concrete works required.
  • Full Roof filters allow for Downdraught air
  • .25 m/s vertical downdraft airflow
  • 4114.1:2003 Compliant & Certified
  • Pressurised Environment with supply fans
  • Machinery can be floor or roof mounted: This design of booth does have a large footprint.
  • Modular Standard Sizes & Oversized Options available
Full Downdraft Spray Booth

Full Downdraft Pit Truck Booth

The in ground pit full downdraught delivers the industry benchmark of paint booths for Truck and large equipment spray painting applications. This airflow method provides the best airflow pattern with all over-spray directed underneath the painters feet ( pulled through the floor) irrespective of where the painter is standing. With this single pass design the booth provides superior cleanliness and quality of finish.

The “full” refers to the entire roof plenum being supply air filters and the “pit” refers to the underfloor concrete works that provides the exhaust plenum ventilation. 

Full Downdraft with pit provides the ultimate in cleanliness and airflow efficiency. 

Key Benefits

  • Industry Benchmark as best airflow method
  • Ventilation is underfloor ( Concrete work required )
  • Full Roof filters allow for Downdraught air
  • .25 m/s vertical downdraft airflow
  • 4114.1:2003 Compliant & Certified
  • Pressurised Environment with supply fans
  • Floor grates underfoot
  • Machinery can be floor or roof mounted: This design of booth does have a large footprint.
  • Modular Standard Sizes & Oversized Options available


Truck and Bus Spray booth

Why should I get heating?

A key decision when deciding on what type of Truck booth to install is heating. The most compelling reason to add heat to a spray booth is increased adhesion quality during spray cycle and accelerated curing in bake cycle. Adding heat is all about increasing throughput, reducing the bottle neck by waiting for paint to dry and increasing adhesion quality of your spray by having a warm sub-strait for applying paint.

Increase Quality and productivity – Heating

By adding heat to your spray booth you are controlling the environment in which you apply paint far more accurately. The ideal temperature for applying paint to a substrate (truck or part) is 20-30.C to ensure proper adhesion and uniform thickness with no runs. If the substrate is too cold (such as in a non-heated booth particularly on a cold morning) the paint coating is much more difficult to apply and it could cause the adhesion to fail immediately requiring reworks or over time resulting in a poor quality end product. Heating is a must if you plan to paint at any time of the day and if you don’t want to be controlled by the seasons.

If no heating is fitted – its all about timing.

Great coatings can be achieved in non-heated booths it’s just one time consuming. You need to pick a warmer part of the day so that the air coming in is not too cold, and you also need to mix the appropriate hardener / paint ratio to ensure the paint can cure in the colder environment. If volume production is not your concern then certainly non-heated booths suit your application, but if you want volume production and flexibility to paint any time in a controlled environment then heating is the best way to go.

Sub-strait temperature when painting trucks

As mentioned earlier substrate temperature is critical to paint adhesion. When looking at Trucks specifically they tend to be made of thick steel materials that hold temperature. Getting these substrates up to spray application temperature can take a long time if no heating is fitted to your booth. A heated truck spray booth will allow the user to heat the truck quickly and be ready to paint in a fraction of the time
