What are Spray Guns? Functions and Uses

An essential component of all industrial spray machines, spray guns are the handheld devices that technicians use to apply spray materials. They are typically connected to larger systems and prompt the rest of the spray machine to mix, transport, and spray the fluid materials via a trigger.

These products come in varying types, have an assortment of features, and are designed by a range of different manufacturers. Overall, they help make spraying jobs more efficient, cost-effective, and higher quality.

Types of Spray Guns

The spray industry is quite diverse with a range of different spray materials and surfaces. As such, there are many different spray gun types available to meet these requirements. Bolair focuses on stocking the most versatile iterations on the market, ensuring that every customer will find an option that perfectly suits their needs.

Airless spray guns are the most commonly used. They are powered by a motorized pump (either electrical or hydraulic) and offer high-power operation, customizable spray patterns, and uniform coatings.

Manual spray guns feature a user-controlled trigger assembly and are perfect for less demanding operations where an expensive automatic system is overkill. They are much easier to maintain, as the spray gun parts can be easily swapped out. Manual spray guns can be more effective than automatic spray guns in the hands of a skilled technician, as the operator can make on-the-fly adjustments.

Automatic spray guns and powder guns are typically used in demanding production lines. They can be either user-controlled or integrated into an automated, robotic system. Automatic guns do not have a trigger assembly and will spray continuously. This can be very beneficial for novice spray technicians or for situations where speed and extensive coverage are important.

Thinner spray materials like primers and lacquers require sensitive spray guns. Most fine finish guns are high volume low pressure (HVLP), ensuring optimum transfer efficiency.

Texture guns are most often airless and are used for applications like fireproofing, drywall, and some roof coatings. They’re designed for high-viscosity materials like ready-mix and powdered joint compounds, but can also be used with standard paint.

Waterproofing guns are extremely heavy-duty and feature a very high flow rate that makes it possible to apply thick coverage in fewer coats.

As the name suggests, foam guns are utilized by the spray foam insulation industry. They can be either air-purged, mechanical-purged, or solvent-purged, and are engineered to specifically handle high-viscosity, plural component materials.

The thicker viscosities of plural component materials like polyurea need specialized components throughout the entire system. Accessories like heated hoses and transfer pumps ensure that the polyurea guns will be able to perform at maximum efficiency.

Many of the spray guns used for polyurea can also be used for floor coatings and repairs. They feature shorter stroke lengths that are ideal for fast-setting materials and have varying mix chamber sizes for different applications.

Protective coatings guns are often the same guns used for other applications like fireproofing, floor coating, texture coating, and fine finishes. They come in a wide range of pressure ratings and fluid compatibilities.

Hoses are essential to the functionality of any spray gun. It’s important to choose a product that matches the material, temperature, and pressure requirements of the spray project. Gun & hose bundle kits are available for convenience.

Air-assisted guns are hybrids, as they rely on both a hydraulic fluid motor and compressed air. The motor will typically pressurize the system to a halfway point, where the compressed air then takes over the disperse the spray material from the gun. With a high transfer rate and application speed, they’re one of the more expensive air spray guns available.

Main Features and Capabilities

There are several spray gun parts and features that are used in all industries. The air cap is found on all guns and is responsible for atomizing and directing the fluid materials. This can often be customized and dictates the shape of the fan pattern. The nozzle is the component that meters the amount of fluid that enters the spray gun, controlling the flow rate of material as it exits the system.

Many brands like Graco have specialized features. For example, ClearShot technology is used with liquid purge spray guns to automatically clear the chamber of any excess residue, drastically reducing cleaning times. ProConnect technology is another proprietary feature that makes spray gun rebuilds a breeze.

Industries That Utilize High-Performance Spray Guns

Coatings are essential for a wide range of purposes, including protection, insulation, weather resistance, and visual appeal. Their specialized construction is necessary to accommodate a range of different industries, such as:

Manufacturing:

Automotive spray guns are used in vehicle manufacturing for the painting, powder coating, protective coating, and fine finishing of frames and exposed metal.

Painting:

Exterior painters find that the efficiency and quality of their work are drastically improved when using spray guns over brushes.

Consumer Goods:

Many consumer products have a final painted or powder-coated layer that protects them from wear and makes them ready for the shelf.

Structural Fabrication:

Civil structures like bridges and skyscrapers all feature strong steel beams that are fabricated with protective coatings for resistance against the elements and corrosion.

Spray Foam Insulation:

Large-scale spray foam insulation projects utilize high-end machines and spray guns for more efficient and uniform application.

Fireproofing:

Often used in construction, spray guns are used to apply fireproof coatings to elements of the building like the walls.

Floor Coating:

Many floors, such as the ones found in garages and commercial spaces, utilize plural component spray systems and guns for epoxy and polyurea coatings.

Commercial Roofing:

Many commercial, flat-roofed buildings take advantage of the speed at which spray on roof coatings can be applied.

Benefits of Using Spray Guns

Improved Accuracy

Spray guns meticulously control the application of fluid materials. Competent spray technicians will find that using a high-quality spray gun will improve the accuracy of their coatings, resulting in less overspray and fewer coverage gaps.

Maximum Efficiency

The speed at which a spray job can be done using a professional gun is impressive. Higher-powered machines can cover the same amount of area in one hour that it would take a contractor to do by hand in a day.

Better Surface Quality

There is minimal margin of error with spray guns. The technology within the device creates uniform spray patterns with a consistent amount of material. This results in a much higher-quality surface finish that’s free from blemishes, drips, and thin coverage spots.
