Variable Airflow Technology
Large increases in energy costs have forced body shops to look closely at whole life operating costs. Spray booth energy costs vary from extremely expensive to as little as a few dollars per job, depending upon the booth technology, type of fuel, the burner used and type and size of the air handling plant.
Junair has developed an energy efficient air handling plant that delivers the lowest energy consumption/cost per job. While the use of variable speed drives on paint spray booth motors is not a new concept, Junair has been using them for the last decade. Junair has developed a completely unique system which varies the airflow volume to suit each process in a booth cycle.
The system, which is fully automatic, requires no operator selection so the energy savings are always guaranteed.
By reducing the airflow throughout the cabin, we are able to lower fuel consumption related energy costs. 100% airflow is not needed when the booth is standing idle or when vehicles are being loaded and unloaded into the cabin. That would be like sitting in your car at traffic lights with your foot hard on the accelerator.
- Load, unload, cleaning, idle
- Low airflow, reduced by 75%
- Flash off base coat
- Medium airflow, reduced by 50%
- Spray application
- High airflow, 100% air volume used on spray cycle
- Bake cycle
- Medium airflow, reduced by 40%
When combined with QADsTM, Variable Airflow Technology can save 65% of spray booth energy costs.
Fuel Saver Mode
Even further energy savings can be achieved during the process when the Fuel Saver Mode (FS) is coupled with the Junair spray booth air handling plant.
The energy used by a spray booth is mostly used up when heating the external air to meet the requirements and conditions of the spray booth cabin, which is normally 22 degrees centigrade for spraying. When the Fuel Saver (FS) mode is installed, this will automatically alter the air handling plant temperatures during idle and flash off to recirculate the air.
The system requires no operator input and therefore the savings are guaranteed. Safety interlocks have been installed to ensure that the system is safe to operate at all times.

LED Lighting
The quality of the lighting within the spray booth is integral when considering the purchase of lights.
Standard fluorescent lighting tends to deteriorate in both colour and brightness with age. LED lighting is the most efficient and cost effective in the long run, with estimated energy efficiency of 80% to 90% when compared to conventional lighting.
If you take a longer term view of operating costs and make the switch to LED lighting, the savings will be greater long term. LED lighting is just about maintenance free and in most cases will operate from between 10 to 20 years without maintenance without the compromise of high lux levels. So, you end up with longer life lighting with more savings.
From the point of view of the environment, LED lighting is the “green” option. Fluorescent tubes contain lead and mercury. With the shift towards “greener” lighting solutions, we expect fluorescent tubes will become more expensive and harder to source.
LED lighting is not just for new booths, they can also be retro fitted into just about any existing booth or paint mixing room.
Paint Booth Control Panel
Each Junair spray booth model has the option of a conventional push button / switch control panel or a PLC and colour touch screen technology which we call i System2 .
Both of these control systems are very simple to operate and have proven to be extremely reliable in use.
There are significant benefits for the owner and operator of the i System2 . With pre-programmed bake cycles, it ensures paint jobs are not under or over cured in order to deliver a perfect cure.
It also ensures you are saving time and being energy efficient while delivering the best result possible. Operators can select from a list of coatings which are shown on the touch screen, the PLC automatically runs the most efficient cure profile to suit the product.
The i System2 will automatically balance the air pressure in the Junair spray booth cabin with no operator input needed. This ensures that the airflow is always maintained at optimum levels.
The i System2 has a Remote Diagnostic Upgrade option. The PLC and touch screen have in-built web server functions that have been used to develop a comprehensive remote diagnostic system. If there is a fault, a Junair engineer will be able to remotely interrogate the control system on-line to diagnose the problem quickly and efficiently. All the settings can be changed without the need of an engineer being on site.
The control software can be upgraded remotely as well.
Air Handling Plant
Junair Spraybooths have developed an energy efficient air handling plant that delivers low energy costs. While variable speed drives are nothing new, Junair’s unique system, Variable Air Technology (VAT), varies the airflow volume in the cabin to suit each individual process. By reducing the airflow through the cabin, fuel and electricity costs will decrease. When the booth is standing idle or when vehicles are being loaded and unloaded 100% air flow is not required. Below is a table of the individual processes and the air flow reductions:
- Load, unload, cleaning, idle – Low airflow, reduced by 75%
- Flash off base-coat – Medium airflow, reduced by 50%
- Spray application – High airflow, 100% air volume used on spray cycle
- Bake Cycle – Medium airflow, reduced by 40%
It is a fully automatic, self contained system than can be retro fitted into any spray booth.
By combining this technology with QADsTM, you can save 65% of your spray booth energy costs.
EVAC LEVAC Floor
The EVAC and LEVAC floor designs are unique to Junair and have been developed to suit the specific needs of the painting process.
The EVAC and LEVAC floors help to create an environment where process efficiency is paramount and where health and safety for the spray booth operator are at optimum levels. Coupled with the full length, full width ceiling filters found on Junair spray booths, the EVAC and LEVAC floors maximize the size of the spray zone (or clean zone).
The Junair EVAC floor is designed so that the floor grating is flush with the building’s floor level. It is important to note that a recess in the building slab of 500mm is required for construction.
The Junair LEVAC floor was designed to surface mount, which means it requires no builders-work excavation. The height from the building floor to the spray booth floor is only 140 mm and only a 1 metre, unobtrusive ramp is required to access the spray booth cabin.
This in turn makes it easier to load and unload vehicles. It removes the excavation element which significantly reduces your installation costs and also removes the shop floor disruption associated with excavation at a work site and allows for quicker installation.
Features and benefits of EVAC and LEVAC include:
- A fully extracted and balanced floor which provides better air movement when painting off car panels and a vehicle together. This prevents cross contamination from over spray and speeds up the curing process.
- Mist clearance times are greatly reduced, which creates a safer environment for the painter.
- Remember, no excavation is required for the Junair LEVAC floor, which saves money and work disruption for your business.
