Types of paint sprayers
There are seven types of paint sprayers. These are, Air gun paint sprayers, Electrostatic paint Sprayers, Electric fan, automated linear paint spray systems, automated flat line paint spray systems, Airless spray guns and spray booth.
- Air gun paint sprayers
- Electrostatic paint Sprayers
- Electric fan
- Automated linear paint spray systems
- Automated flat line paint spray systems
- Airless Spray gun
- spray booth
1. Air gun paint sprayers
General Process-
Uses an air pressurized gun sprayers. When the trigger is pushed, the liquid paint is mixed with the compressed and creates a paint stream through the nozzle.
Components- Air compressor, Nozzle and A paint basin
Type of technologies-
HVLP: High Volume Low Pressure. In this technology, the gun sprayer uses a compressor to supply the air, but the gun itself works in a lower pressure.
LVLP: Low Volume low pressure. Just like the gun sprayer, the overall system also works in low air pressure.
Specially used in painting-Cosmetics, architectural coating, decorative, marine coating and automotive industries.
2. Electrostatic paint Sprayers
General Process-
In electrostatic spray painters, otherwise named powder coating, the paint particles are atomized and electrically charged, so that they repel each other and evenly spread after leaving the nozzle.
Components- A spray nozzle, a paint supply reservoir
Type of technologies-
Direct Charging: The electrode is inserted into the paint reservoir
Tribo Charging: It uses the friction energy of the paint that is forced through the paint sprayer.
Post-atomization charging: The paint fluid is atomized and put into an electrostatic field from the outlet nozzle.
Specially used in the painting-Car body panel, bike frame
3. Electric fan
General Process-
The sprayer combines the paint with air or convert the paint liquid in to tiny droplets to accelerate out of the nozzle.
Components- A spray nozzle with a mini fan attached, a paint supply reservoir
Type of technologies-
Hot spray: In this type, the paint in the reservoir is heated to 60-80 °C in order to apply thicker coat.
Air assisted spray guns:
In this case, the fluid pressure is raised to 300 to 3000 pounds per square inch for the atomization of the coating.
Specially used in painting-Walls, wooden and metal objects
4. Automated linear paint spray systems-
General Process-
The automated linear paint system is heavily used for recovering paint. In this process, the spray gun is placed above the product and paint using the water-based or solvent-based coating.
Components- A spray nozzle, a paint supply reservoir
Type of technologies-
This incorporates paint-saving technology in order to decrease the amount of paint and gives the capability to reuse the paint.
Specially used in painting-Window frames, baseboard casing, trim stock, wood molding
5. Automated flat line paint spray systems
General Process-
Flatline paint sprayers aligned above a largely automated conveyer belt for painting small and complexly shaped materials.
Components- A spray nozzle, a paint supply reservoir, An automated conveyer belt, Air compressor
Type of technologies-
In this case, the paint sprayers are put above the conveyer belt. The conveyer belt is automatically moving and the sprayers’ auto move for covering all the side of the material evenly with the paint.
Specially used in painting-Wooden, Plastic and kitchen products.
6. Airless Spray gun
General Process-
Airless sprayers use a high-pressure pump to pressure the atomize paint coating inside the paint reservoir.
Components-
A spray nozzle, a paint supply reservoir, high-pressure pump, or air compressor for power generation.
Type of technologies-
In this process, the paint in the reservoir is provided with a negative charge and atomized. By attaching a high pressure, pump providing 300 to 7500 pounds per inch. After that, the paint is sprayed with use of a nozzle.
Specially used in painting-Heavy-duty industrial painting, chemical and marine coating, and linings.
7. spray booth
General Process-
A spray booth uses a pressure-controlled environment for efficiently painting a large or small object safely from distance.
Components-
Pressure Controlled closed environment, paint sprayers (Automated or manual), Intake and exhaust filters
Type of technologies-
There are 5 types of paint booths. Crossflow, side downdraft, Semi Down Draft, Full Downdraft, and open-face industrial booth.
Specially used in painting-Auto Body shops
