Every DeVilbiss Spray Gun is a precision instrument, engineered to minute tolerances to ensure consistent performance and accurate colour matching under the toughest paint shop conditions. Ensuring we have total control over production of every professional spray gun we sell means we can control the quality of every single component from the cheater valve to the fluid tip and can offer the best parts back up in the industry, so you can keep your DeVilbiss spray gun performing to the max, day in, day out.
Here at Devilbiss we understand that from time to time new parts may not be the solution and a few simple steps may be all it takes to get your equipment back to optimum working conditions. You will find practical advice in our troubleshooting and FAQ sections but if you’re still searching for an answer why not contact us and get your query answered by our technical specialists.

There are 2 small holes in the lid of the gravity cup which allow air to enter the cup as the paint level reduces. If one or both of this holes are blocked then paint flow will be reduced and eventually stop all together.
Yes you can, the clip is only there to avoid the cap falling from its retaining ring which could cause unnecessary damage.
The filter should be picked up by the small stem and then inserted in the stainless steel fitting on the gravity cup, with the open end of the filter facing into the cup. Then the cup can be safely screwed in the gun.
After prolonged use the air cap and retaining can be contaminated internally, which may not be visible. Remove the spring clip from the rear of the air cap to allow better access to any hidden paint build up.
We recommend the use of our gun maintenance kit, KK-4584, which includes all the necessary tools to help keep your gun in tip top condition. Alternatively use a wooden toothpick, which will not damage the air cap.
This problem occurs when air is being drawn into the fluid passageway. The main cause of this is a loose fluid tip. Re-tighten the tip using the correct spanner.
The gasket is reusable and therefore does not need to be replaced each time you clean the gun, but make sure it is not damaged before refitting and replace if necessary.
All of the GTi Pro air caps have paint company approvals for the application of waterborne basecoats. Please refer to our paint data sheets on this website for each individual recommendation.
There is very little difference to the inlet pressure whether you half or fully trigger our sprayguns, unlike some of our competitors, so either method is correct.
Make sure that the air flow control valve is left fully open; this will ensure that the DGi is reading the correct pressure.
High Volume Low Pressure, this refers the air cap pressure and the amount of air volume the gun consumes. By limiting the air cap pressure to 10 PSI (or 0.7 Bar) it produces less overspray therefore making the gun more efficient.
Because etch primers are normally lower in viscosity, a 1.8mm tip maybe too large. You can adjust the fluid control knob on your spraygun, which will reduce the fluid flow, or you can simply fit a smaller fluid tip, which will achieve the same result.
Some disposable cup systems do not fully collapse during use and can trap a small amount of paint. Try our DeKup system which has been designed to improve this issue and will help you save some money.
All DeVilbiss air caps are available as an individual spare part and can be changed without the need to change the tip and needle. Some of our competitors do not allow this flexibility.
The DGi Pod can be fitted in seconds. Using the spanner supplied with the GTi Pro (or another 14 mm spanner) remove the spreader valve from the top of the gun, insert the pod into the same hole and re-tighten with your spanner. And you are good to go!
The PRO-415-1 kit services the whole of the ‘i-system Pro’ family, GTi Pro, PRi Pro and SRi Pro and therefore there is an air seal from the SRi Pro included in the kit.
This deflector plate, SN-41-K, can be fitted either way round.
You can, but try limiting the paint stripper to the areas only where the paint has solidified. If you immerse the whole gun in paint stripper you could damage some of the internal parts.
Behind the fluid tip should be plastic air seal, if this is damaged or missing then the fan control will not work correctly.
There is only one fluid needle for the whole range of different fluid tip sizes so it has no designated size, one size fits all.
