The DeVilbiss FLG5 spray gun series combines performance and cost-efficiency for demanding coating applications. Whether in general industry, craftsmanship, or furniture manufacturing – this spray gun is the ideal tool for a wide range of materials. Our guide shows you how to get the maximum performance out of your FLG5.
FLG5 Overview: Variants and Their Strengths
The FLG5 series offers the right solution for every requirement. The choice between suction feed, gravity feed, and pressure feed determines your workflow.
| Variant | Label | Ideal for | Advantage |
|---|---|---|---|
| Gravity feed | G | Standard applications, medium material volumes | Good control, economical set |
| Suction feed | S | Smaller projects, frequent color changes | Easy cleaning, flexible |
| Pressure feed | P | Large surfaces, high throughput | No interruptions for refilling, faster workflow |
Note: The order designation consists of type (FLG5), air cap (e.g., G5), and nozzle size (e.g., 14 for 1.4 mm).

To the FLG5 Gravity Feed GunRecommended Basic Settings (Reference Values)
For an optimal spray pattern, pressure and material settings are crucial. These values serve as a baseline and must be adjusted depending on material viscosity.
| Gun Type | Air Cap | Inlet Pressure | Air Consumption (approx.) |
|---|---|---|---|
| Cup gun (suction/gravity) | No. 5 | 2.0 bar | 280 l/min |
| Pressure feed gun | No. 622 | 2.3 bar | 310 l/min |
Typical flow rate: 200–280 ml/min. Typical spray pattern size: approx. 200 mm. Material inlet and air inlet have 1/4" universal threads.
Professional Workflow in 6 Steps
- Preparation: Bring material to processing viscosity (according to manufacturer). Clean workpiece and prime if necessary.
- Configure the gun: Select the right nozzle/needle combination (e.g., 1.4 mm) and air cap (No. 5 or 622) and install them.
- Set pressure: Adjust compressor and regulator to the recommended inlet pressure (2.0 or 2.3 bar).
- Test spray: Spray on test surface (cardboard). Evaluate spray pattern (shape, wetness) and material flow. Adjust settings.
- Coating: Hold gun at correct distance (approx. 15–20 cm) parallel to the surface with even speed and overlap (approx. 50%).
- Cleaning: Flush the gun immediately after use with suitable cleaner to avoid residue in the nozzle and channels.
Common Problems & Solutions
1. Orange Peel / Poor Flow
- Material too thick? – Thin with appropriate reducer.
- Air pressure too low or gun distance too large? – Increase pressure or reduce distance.
- Environment too cold? – Warm material and workpiece.
2. Drips from Nozzle
- Needle tip or nozzle seat worn/dirty? – Clean or replace components.
- Material pressure (pressure feed) too high? – Reduce pressure.
3. Irregular Spray Pattern
- Air cap or nozzle clogged? – Clean thoroughly.
- Damaged air cap holes? – Replace air cap.
4. Low Material Flow
- Nozzle clogged? – Clean.
- Material filter (cup/pressure pot) blocked? – Clean or replace.
- Material too cold/viscous? – Increase temperature or thin.
Quick Maintenance Checklist
- Daily/After each use: Flush gun immediately with suitable solvent.
- Weekly/When performance drops: Remove air cap, nozzle, and needle and soak in cleaning solution. Check nozzle seat and needle tip for wear.
- Regularly: Check all seals (O-rings) for cracks or brittleness and replace if needed.
- Air system: Drain water separator and compressor filters regularly.
- Storage: Store the gun fully cleaned and depressurized. Ideally hung to protect seals.
FAQ – Frequently Asked Questions
Which materials is the FLG5 suitable for?
According to the manufacturer, it is suitable for paints, primers, fillers, oils, adhesives and many other solvent-based materials.
What does “Trans-Tech®” mean?
This is DeVilbiss’ patented atomization technology. It enables fine, uniform atomization, resulting in excellent surface quality and reduced material consumption.
Can I change the nozzle myself?
Yes, the fluid nozzle, needle, and air cap are consumables and can be replaced by the user. Make sure to use matching sets (nozzle + needle).
What compressor is required?
A compressor with a delivery rate of at least 300–350 l/min (approx. 5–6 l/s) and a regulator is recommended to keep the required air pressure (2.0–2.3 bar) stable.
What is the difference between air cap No. 5 and No. 622?
Air cap No. 5 is designed for cup guns (gravity/suction). Air cap No. 622 is for pressure feed guns and optimized for higher material throughput.
Conclusion
The DeVilbiss FLG5 spray gun is a versatile and reliable choice for professional users. Its robust construction, efficient Trans-Tech atomization, and flexibility through various cup configurations make it the ideal tool for nearly all coating tasks. With correct settings, a clean workflow, and regular maintenance, you will consistently achieve first-class results and significantly extend the lifespan of your equipment.
