The air hose is the flexible arm of the compressed air system and is very important for a perfect painting result. It should be antistatic (DIN EN 1953), free of paint-disturbing substances, solvent-resistant, flexible and pressure-resistant as well as have a sufficient inner diameter.

"Cheap" air hoses for domestic use (e.g. garden hose) are unsuitable for professional use in a paint shop due to the lack of antistatic properties and the separating agents it contains. 

In the workshop, air hoses are sometimes exposed to high temperature fluctuations, solvents or pressure loads (e.g. if a vehicle drives over the air hose).

If used daily, the air hose should be replaced at least once a year.

When using a water-based paint system, technically absolutely pure compressed air and the use of a three-stage filter (e.g. SATA filter 484 / SATA filter 584) with an integrated activated carbon filter are required.

SATAjet 1000 B

Standard nozzles

The standard SATAjet 1000 B nozzles are used to process all kinds of coating materials, from low-viscosity oils and stains to coloured and textured paints. The standard nozzles of the SATAjet 1000 B distinguish themselves with regard to colour accuracy, surface quality and universality thanks to the broad nozzle spectrum.

• Standard RP nozzle sizes from 0.8 to 5.0
• Standard HVLP nozzle sizes from 1.4 to 2.1

Special nozzles

When it comes to special applications, the SATAjet 1000 B offers various special nozzles. The HV nozzle sets are equipped with short horns in order to reduce air nozzle contamination so that a consistently good spray pattern can be maintained. SATA offers two special nozzle sets to accommodate adhesive processing: There's DA for the processing of dispersion adhesives and D for threading solvent adhesives.

• High-viscosity materials (2.5 and 3.0 HV)
• Dispersion adhesive (1.3 DA)
• Swirl nozzle for solvent adhesives (1.6 D)

Standard nozzles

For when you need to handle larger paint quantities.

• Standard RP nozzle sizes from 0.8 to 5.0
• Standard HVLP nozzle sizes from 0.8 to 2.0

Special nozzles

We also offer nozzle sets with a special surface finish to extend service life when abrasive materials are used. For example, slot nozzle sets are used for high-viscosity textured plasters, façade paints as well as materials with a high proportion of solids.

• Dispersion adhesive (1.3 DA)
• Swirl nozzle for solvent adhesives (1.6 D)
• Nozzle sets with a surface that extends the device's surface life
• Slot nozzle sets

Depending on the area of application and the material to be processed, the paint manufacturer (material manufacturer) will provide a recommendation. These can be found in the technical data sheet. 

A range of available nozzles and coating technologies (e.g. HVLP or optimised high pressure) are often named.

In our data sheets you will find a large number of material manufacturers with their respective recommendations.

SATA spray guns are ready for immediate use right out of the box.

The recommended input flow pressure for the material used can be found in the technical data sheet of the paint manufacturer (material manufacturer). 
Depending on the specific requirements, the input flow pressure, the spray fan shape and the amount of material can be adjusted on the spray gun. This should be done in the following order:

1. Adjustment of the jet shape via round and wide jet regulation
2. Setting material quantity via material quantity regulation
3. Adjustment of input flow pressure via the air micrometer

When using HVLP spray guns, the spray distance should be approx. 10-15 cm; when using RP spray guns, it should be 17-21 cm. This can vary depending on application speed, nozzle size and the material used.

For thorough cleaning, the paint needle, air nozzle and ink nozzle should be cleaned manually (using suitable cleaning tools) at least twice a day. It is the only way to ensure 100% performance over the long term.

Paint needle
The paint needle ensures that material only emerges when you want it to. It has a certain "sealing function". You should pay particular attention to the tip of the paint needle. This ensures that the material arrives evenly at the tip of the paint nozzle. After spraying, clean the tip briefly with a soft brush or a cloth dipped in cleaning agent so that you can enjoy top performance for a long time.

When dismantling the nozzle set, pull out the paint needle first. After cleaning, insert the paint needle last. This prevents unnecessary wear between the paint nozzle and the paint needle.

Paint nozzle
Be mindful with regard to assembling and disassembling the paint nozzle and pay special attention to the paint nozzle tip. It only lets through as much material as is needed and ensures an even ejection of the material, which is then atomised by the air nozzle. On a new spray gun, a material/air ratio calibrated by SATA is pre-defined to ensure certain spraying characteristics. Changes in the material ejection lead to an uneven ratio and result in a poor spraying pattern.
If you clean the paint nozzle with a brush or a paintbrush, your spraying results will look excellent for a long time.

Air nozzle
Although the air nozzle hardly comes into contact with the coating material, it is still the element that gives the spray jet its form. Many small and large holes ensure fine atomisation and an even distribution of the paint. You must always keep an eye on these holes. Make sure they are free of impurities and that the entire air nozzle is in a clean state.

For each (paint) material used, the paint manufacturer recommends a specific cleaning medium so that it can be dissolved and does not trigger any undesired reactions (e.g. flakes). 

The following items are important for use in combination with spray guns:

1. Aqueous cleaning products should have a pH value of 6-8
2. Acids or lyes may not be used for cleaning
3. Spray guns or nozzle sets should not be “soaked” in cleaning solution
4. After cleaning, the spray gun should always be dried (e.g. with a blow gun).

Depending on duration and frequency of use, materials used and the care of the nozzle set, wear and tear occurs in small steps that are not apparent to the naked eye. The naked eye is unable to discern which of the components is most affected by this. 

That is why it makes no sense to exchange only one of the nozzle elements, as this would quite probably only result in another poor spray pattern. In the long term, this means that the paint nozzle, paint needle and air nozzle are generally in different states of wear and tear, which means that a pending change would not be detected. It would thus not be possible to achieve a spray pattern identical to the one that the spray gun provided in its initial delivery state.

Once a nozzle set is worn, the ratio of escaping material quantity no longer corresponds to the atomising air. This means that the intended air volume no longer sufficiently atomises the increased material output, which in turn results in a poor spray pattern and degraded painting results. 

The following faulty patterns could occur:

• Cloud formation in the base coat (for metallic and pearlescent colours)
• Orange-peel effect (clear varnish)
• Darker colour (for metallic and pearlescent colours)

The nozzle set's wear mainly occurs on the parts that have material flowing through them namely the paint nozzle and paint needle. 
Because of the material flow, the material in the paint channel "rubs" against the paint nozzle and needle and thus causes wear. The wear of the nozzle parts varies according to the type and composition of the material and the duration of use.

When cleaning the spray gun and disassembling the nozzle set, care should be taken to ensure that the needle is not mounted while unscrewing the paint nozzle, since the paint nozzle rubs against the paint needle because of the rotational movement, thus causing artificial wear. 

These fundamental principles apply...

...during disassembly:

1. Remove paint needle
2. Remove air nozzle
3. Remove paint nozzle

...during assembly:

1. Mount paint nozzle
2. Mount air nozzle
