Equipment for high pressure spray

Normally, the angle of airless nozzle can not be adjusted because the nozzle must be suitable for high pressure resist at 250 bar. But when using with air coat method, air cap will provide the low air pressure to adjust the spray pattern to be width and thin size which is similar to ordinary air spray gun but the angle can be adjusted not more than limitation of angle size in each nozzle. The presentation will be separated into 2 topics are following as below;

  • Flat Spray Pattern (Nozzle and Air Cap for flat pattern)

  • Round Spray Pattern (Nozzle and Air Cap for round pattern)

Component of Flat Spray Pattern

  1. Shaping air for control the shape of spray pattern

  2. Variable spray jet width that it can be adjusted

  3. Air Cap or release air pressure

  4. Atomizing air

Spray Method of Flat Pattern

Flat Pattern Application

 

In this pattern, paint pressure at nozzle is 30 - 150 bar and air pressure will be 0 - 2.5 bar will be the suitable rate for flat spray pattern in order to prevent the over spray issue and be enable to adjust the pattern size which depend on limitation of angle size of nozzle

Advantages of Flat Pattern

​​

  • Large application volume

  • Low fogging tendency

  • Good fi nish

  • High viscosity products can easily be applied

  • High endurance of the nozzles

  • Jet width adjustment

1.1 Air Cap and Nozzle for Flat Nozzle

ACF 5000 Air cap for Flat Spray Pattern

 

Air Cap for GM5000EAC that it is designed for flat nozzle for high pressure spraying and make the low air pressure to control the spray pattern. There have 2 types of air cap.

EAC Air Cap RED.png

ACF5000 Red Air Cap

 

For low viscosity material that it is marked by red color on air cap.

EAC Air Cap Blue.png

ACF5000 Blue Air Cap

 

For high viscosity material that it is marked by blue color on air cap.

ACF5000 Flat Nozzle

Nozzle for high pressure spray that the nozzle size will be smaller than nozzle for air spray because it must be applied at pressure level up to 250 bar and fixed angle spray following each nozzle. The nozzle can be identified by reading number such as "No. 13/40".

Remark

 

However, as the nozzle is used for air caot spray gun. ACF5000 air cap can help spray pattern to adjust the variable pattern to be width or thin on demand but it must not over than 40 angle so if maximum angle pattern is 60, the variable pattern can be adjusted not more than 60.

How to read the nozzle number

No. 13/40 is the 2 position number. The 1st position "13" came from 0.013" and 2nd position "40" came from angle at 40. so "13/40" is mean this nozzle is 0.013" and maximum pattern angle is 40.

Component of Spray Pattern

  1. Low air pressure which control high pressure airless spray pattern

  2. Paint flow to spraying section and be sprayed by airless high pressure spray.

  3. Nozzle Nut

  4. Multi-Channel swirl nozzle

  5. Round high pressure spray pattern

Round Spray Pattern Picture

Round Nozzle Application

In this pattern, paint pressure at nozzle is 30 - 150 bar and air pressure will be 0 - 2.5 bar will be the suitable rate for flat spray pattern in order to prevent the over spray issue and be enable to adjust the pattern size which depend on limitation of angle size of nozzle

Advantages of Round Spray Pattern

​​

  • Large application volume

  • Low fogging tendency

  • Good fi nish

  • High viscosity products can easily be applied

  • High endurance of the nozzles

  • Jet width adjustment

2.1 Air Cap and Nozzle for Round Spray Pattern

ACR5000 Air Cap for Round Spray Pattern

 

This round spray air cap is built for solvent-based material only. Please see details of air cap on below

Air Cap ACR5000 (2354486) is compatible for all size of round nozzle and apply with every viscosity level.

ACR5000 Nozzle for Round Spray Pattern

 

There have 12 size for round nozzle by using "R" as the identity code and be followed by number. This number present the diameter size. For example, R15 is 0.015". You can see the table of round nozzle as below;
