Spray painting equipment in Nigeria from the Tikweld team

Spray painting equipment refers to the collection of devices used to apply a surface coating to objects by the means of atomized liquids that are propelled through the air, usually by compressed air. It also refers to a series of devices used to optimize the coating application. The Tikweld team will list all the spray painting equipment information for Nigeria

Paint spraying is based on atomizing technology

Generally speaking, there are four methods utilized to produce droplet-sized particles and impart direction upon the spray agent. This technology in conjunction with the applicator determines if the spray pattern and intensity.

  1. Airless Sprayers: Paint spraying or application system using high fluid pressure to atomize paint by forcing it through a small orifice. It sprays medium to high viscosity fluids for a finish quality better than airless, but not as quality as air spray. 
    Paint under high pressure is passed through a nozzle and broken down into droplets, or "atomized," where it enters the lower pressure region outside the gun tip. (Less air is used than in conventional air spraying so that the problems of dry spray and paint bounce-back is reduced.)
  2. Airless (air-assisted): Air-assisted airless uses a high-pressure fluid for atomization and compressed air at the cap for pattern controlAir-assisted airless spray process is used to alter the spray fan shape pattern, but not to atomize the paint.
  3. Air atomized: Paint application system wherein paint is atomized by combination with compressed air. System of applying paint in the form of tiny droplets in air, i.e., paint is broken down into droplets, or "atomized," by a spray gun as a result of being forced into a high velocity air stream. Shape and paint density of the resulting droplet cloud can be controlled by air pressure, paint viscosity, and gun tip geometry.
  4. Rotary cup/disc: Rotary spray guns or applicators use a rapidly spinning cup/bell or flat disc to project powders or atomize paint. Rotary cup or bell rotary applicators produce a fan pattern, which is closer to a nozzle spray gun. A rotating head is shaped to deliver paint forward in a circular pattern. The bell may be directed at any angle and be moved on robots or reciprocators, just as nozzle spray guns are. Disc rotary applicators spin the coating media out radially. Rotating heads that deliver paint horizontally 360° around the head are useful on omega loop conveyor finishing lines. A disk is usually mounted horizontally on a vertical reciprocator. Disc rotary spray guns are also useful for internal or ID coating applications.

In an effort to reduce energy and material consumption, many spray painting operations systems utilize high volume, low pressure (HVLP) or low volume, low pressure (LVLP) systems to spray coat items with large surface areas. These spray techniques are often driven by turbines, not compressors.

Spray Painting Process

A paint, stain, ink, varnish, lacquer, or polyurethane is pressurized and forced into droplets or aerosol by a high-velocity airstream that also serves to distribute the coating on a surface. The spray is patterned onto the workpiece by an applicator, and cleaning and curing equipment helps perfect the paint's adhesion. 

The following components are utilized in commercial and industrial painting applications.


A nozzle, gun, or wand utilizes the Venturi effect to coat a surface. The tools are meant to be handheld or used in an automated paint spraying system. These dictate the pattern, droplet size, angle, and intensity of the spray. Some spray systems support multiple applicators.

Power source of spray painting equipment

A powered paint sprayer is supplied by either a gas-powered or electric motor, whose operational strength is rated in horsepower.

Source of pressure for spray painting

An air compressor or pump feeds the surface coating through the painting system. This contributes to the flow rate of the paint and pressure is represented in PSI. Turbines are also commonplace.

Media and mixers

A variety of surface finishing liquids can be applied by a spray system, though latex or oil-based paint is most common. Other agents may require thinning to be used in spray systems.

Paint reservoir 

The system's integrated basin for paint awaiting application. These range in size from small cups to paint drums.

Paint handling equipment

Large, heavy-duty paint spraying systems, or systems meant to paint outdoor terrain, often require a truck or cart for transportation or operation.

Paint application enclosures

Since between 20 to 40 percent of the spray can be lost due to overspray and droplet drift, spray booths keep wayward particles within an enclosure. These range in size from cabinets to garage-like environments to accommodate a variety of components.

Ventilation equipment

Due to the airborne concentration of minuscule paint droplets, respirators and ventilation equipment are often legally-required components in the spray painting process. Spray booths often incorporate a blower or overhead hood.
