Pressure Tank System "small" (10 Liters): Apply Booth Protection & Primers Efficiently
If you want to spray booth protection, peelable lacquers, or primers evenly and reliably, a pressure tank system is often the next logical step: constant material flow, controllable air/material pressure, and clean handling in everyday operations.
Quick Overview
- Steel pressure vessel with hand stirrer, mobile on 4 wheels, transport handle
- Double regulator fitting for air and material pressure + safety valve
- Removable aluminum inner container, lid airtight via wing nut closures
- "Small" version: 10 liters incl. hose pair (7.5 m)

|---|---|---|---|---|
| PRESSURE TANK SYSTEM „small“ Art. No. 1640010 |
10 Liters | incl. (7.5 m) | Booth protection media, peelable lacquers/coatings, primers & other water/solvent-based liquids | Hand stirrer, double regulator (air/material), safety valve, aluminum inner container, airtight lid |
| PRESSURE TANK SYSTEM „medium“ Art. No. 1640020 |
20 Liters | without (optional) | Higher consumption/surface area, longer spraying intervals | Same as „small“, larger supply |
| PRESSURE TANK SYSTEM „large“ Art. No. 1640040 |
40 Liters | without (optional) | High area performance, industrial cycle times | Same as „small“, maximum capacity |
Note: The system is designed for booth protection products as well as other water/solvent-based liquids; max. working pressure of the system: 4.1 bar. (See „Product Information“ and catalog specifications.)
KPI
10 Liters
Compact size („small“) – good for changing materials & short setup times.

7.5 m
Standard hose pair (only for „small“) for air and material supply.
Practical Tip (Quickly Effective)
Use the hand stirrer briefly before starting the spray to keep the material homogeneous – especially with thicker booth protection media. This reduces fluctuations in material flow and makes the double regulator setting more reproducible.
CTA: Directly to the Right System
If you are looking for the 10-liter variant incl. hose pair, you will find it here – ideal if you want to set up a compact system for clean spray work.
Recommended Basic Settings (derived from manufacturer specs, as guide values)
- Upper Working Pressure Limit: Pressure tank system up to max. 4.1 bar (do not exceed; manufacturer value).
- Hose Guide Value (Load Capacity): Twin hose for air/material up to max. 8.5 bar (manufacturer value; system limit remains 4.1 bar).
- Regulation: Use the double regulator fitting separately for air pressure and material pressure – start with conservative settings and work your way in small steps toward the desired spray pattern.
- Optional Spray Setup: For a matching suction cup gun, a 3.0 mm nozzle is mentioned in the catalog (as an accessory/component, depending on the application).
Note: Specific pressure values for your material depend heavily on viscosity, hose length, gun/nozzle, and desired spray pattern. Without material-specific data, further numerical values remain intentionally „guide values“.
Professional Workflow (5–7 steps, practical)
- Prepare Material: Provide suitable booth protection medium or liquid (water/solvent-based according to manufacturer instructions).
- Use Inner Container: Fill material into the aluminum inner container, close the lid, and secure it airtight using the wing nut closures.
- Connect: Connect the compressed air supply and spray gun; for the „small“ version, the hose pair (7.5 m) is included as standard.
- Homogenize: Use the hand stirrer briefly until the material is uniform.
- Adjust Regulator: Gradually adjust air and material pressure via the double regulator (observe the 4.1 bar system limit).
- Test Spray: Spray briefly on a sample/test piece, check the spray pattern, then fine-tune.
- Production: Work evenly; for longer intervals, stir the material briefly again to maintain consistency.
Troubleshooting (4 typical problems + measures)
1) Uneven material flow / "pulsating" spray pattern
- Homogenize material before starting with the hand stirrer (compensate for viscosity/separation).
- Adjust regulators step by step: Fine-tune air/material pressure separately via the double regulator.
2) Too little material at the gun output
- Check hose routing (avoid kinks/pinching); on the „small“ version, the hose pair is 7.5 m long.
- Increase material pressure controlled via the material regulator (within system limits).
3) Leakage at the lid / pressure drops
- Tighten wing nut closures evenly in a crosswise pattern so the lid sits airtight.
- Ensure the inner container is correctly inserted and no foreign particles are in the sealing area.
4) Material too thick for clean spraying
- Check material suitability: The system is intended for booth protection products and other water/solvent-based liquids.
- Consider optional spray setups (e.g., the 3.0 mm nozzle mentioned in the catalog for a suitable gun) – depending on the material, a matching nozzle can be decisive.
Maintenance (5 points, quickly implemented)
- Clean the aluminum inner container after use (avoid material residue).
- Check hoses regularly for abrasion/kinks (air/material separately).
- Visually inspect the safety valve (avoid damage/contamination).
- Keep wing nut closures and sealing areas clean so the lid closes airtight.
- Keep the hand stirrer moving freely (remove buildup so homogenization remains reliable).
FAQ
1) What is the pressure tank system specifically intended for?
For booth protection products (e.g., adhesive lacquers/peelable lacquers/peelable skins/oven protection) as well as other water- or solvent-based liquids – especially for spray work in industry and trade.
2) Which variant includes the hose pair as standard?
Only the „small“ (10 liters) variant includes a hose pair (7.5 m) as standard.
3) What pressure limit do I need to observe?
The pressure tank system is specified with a max. working pressure of 4.1 bar. You should not exceed this upper limit.
4) Why is an aluminum inner container useful?
Because it is removable: This facilitates handling and cleaning – especially when you change materials or want to be ready for use again quickly.
5) Can I connect the system directly to compressed air and a spray gun?
Yes – it is designed to be connected to a compressed air supply and spray gun; regulation is handled via a double regulator fitting (air/material).
Conclusion
The DREHKOPF pressure tank system „small“ (10 liters) is a compact, mobile setup for clean spray work regarding booth protection and related liquids: featuring a hand stirrer, double regulator fitting, safety valve, and removable aluminum inner container. If you are looking for a 10-liter solution incl. hose pair, the „small“ variant is the pragmatic choice – accessible directly via the CTA.
