Abrasives are essential for any surface preparation project. They are used for several distinct purposes:

• To remove rust: Abrasives can effectively remove rust, paint or other coatings from metal surfaces, making them an essential tool for industrial cleaning and maintenance.
• To prepare surfaces: Before applying a new coating, surfaces need to be properly prepared. Abrasives provide the necessary roughness and texture for coatings to adhere to, ensuring long-lasting results.
• To improve surface finish: In some cases, abrasives are used to refine the surface finish of materials such as wood and metal, providing a smooth and polished appearance.
• To remove paint: When repainting a surface, abrasives can be used to strip off the old paint and prepare the surface for a new coat.
• For micro finishing: Abrasives are also used for precision work, such as micro finishing and polishing of delicate surfaces.
• For shot peening: In the aerospace and automotive industries, abrasives are used for shot peening to increase the durability and strength of metal components.

Types of Abrasives

We offer a huge range of abrasives at Dawson Macdonald, from brown and white aluminum oxide to glass beads, silicon carbide, alumina zirconia, plastic media and more. Other options like steel grit, steel shot and more are also available.

Furthermore, our team of experts will help you narrow down your options based on your specific project requirements, considering factors like surface material, desired finish, and budget.

For many industries, air blast equipment is an essential part of the surface preparation process. It uses compressed air to propel abrasives at high velocities onto surfaces, effectively removing contaminants and preparing them for further treatment.

Types of Air Blast Equipment

At Dawson Macdonald, we offer a variety of air blast equipment options, including:

• Air blast cabinets: These enclosed cabinets are ideal for smaller, precision cleaning and finishing applications.
• Air blast rooms: For larger projects, air blast rooms provide a contained space for blasting operations.
• Automated blasting systems: These systems use robotics and automation to increase efficiency and accuracy in the blasting process.
• Portable air blasting equipment: For on-site or mobile surface preparation needs, we offer portable blasting equipment options that are easy to transport and set up.

As environmental regulations become stricter, dust collection equipment has become an integral part of surface preparation operations. It helps capture and filter out airborne particles created during blasting, ensuring a safe working environment for operators.

At Dawson Macdonald, we offer a range of dust collection equipment options. Our team will work with you to determine the best solution for your project needs, whether it’s a portable dust collector or a large industrial system.

Types of Dust Collection Equipment

Our selection of dust collection equipment includes:

• Cartridge style: Using a number of cartridges to pull and filter out dust particles, this type is ideal for operations like metalworking, woodworking, laser cutting and more.
• Bag style: This type of equipment uses bags to collect and contain dust particles, making it a more cost-effective option for larger projects.
• Portable: These customizable dust collectors are perfect for on-site or mobile operations, providing flexibility and convenience.

Often when preparing metal or concrete surfaces for welding or coating (or similar needs), the use of shot blasting equipment is valuable. This process removes rust, paint, and other contaminants, leaving a clean surface that is ready for further treatment.

Why Shot Blast Equipment is Beneficial

There are several benefits of using high-quality shot blast equipment, including:

• Efficiency: Shot blasting can be a faster and more efficient method compared to other surface preparation techniques, saving time and labor costs.
• Versatility: It can be used on a variety of surfaces and materials, making it a versatile solution for many industries and applications.
• Cost-effective: With proper maintenance, shot blast equipment can have a longer lifespan and require fewer abrasive replacements, resulting in cost savings over time.
• Environmentally friendly: Shot blasting produces less dust and debris compared to other methods, making it a more environmentally friendly option for surface preparation.

At Dawson Macdonald, we offer several different shot blast equipment options, including the Blastrac 2-20TMKII, the Blastrac 1-8DM, the Blastrac 1-10DSGI, and both the BDC-66 and BDC-99 dust collectors.

As a combination of abrasive and high-pressure water, wet blasting is a gentler form of surface preparation compared to traditional abrasive blasting. It is often used for delicate surfaces or in areas where dust and debris need to be kept to a minimum.

Types of Wet Blast Equipment

At Dawson Macdonald, we offer several different types of wet blast equipment, including:

• Cabinet wet blasting: This format utilizes a cabinet which contains blast media and a workpiece, while high-pressure water is used to remove contaminants from the surface.
• Automation wet blasting: Used for automated production lines, this format is robotic and computer-controlled, ensuring equal coverage. It also utilizes filters that help recycle media and water for sustainability purposes.
• Portable wet blasting: Ideal for smaller, on-site projects, portable wet blasting equipment allows for greater control and precision during the surface preparation process.

Another surface preparation format that uses abrasive material is wheel blast equipment. This type of equipment is designed for high-velocity blasting, making it ideal for heavy-duty applications in industries like construction and manufacturing.

Types of Wheel Blast Equipment

We offer a variety of wheel blast equipment options at Dawson Macdonald, including tumble blasters, table blasters, spinner hangers, pipe blast systems and more. If you ever need assistance in identifying the right type of wheel blast equipment for your specific project, our team of experts is always available to help.

Many facilities utilize industrial vacuum systems to keep their locations dust-free and clean. These systems are highly effective in removing large quantities of debris and dangerous particles from surfaces, making them an important part of maintenance and safety protocols.

Our vacuum systems at Dawson Macdonald can be easily customized, plus are durable and high-performance. They contain universal operations and easy controls, plus utilize only the very best components.

We offer systems ranging from central vacuum systems to direct bagging, fixed silo, mini systems, portable systems and more. Our team will also work with you to determine the best filtration options for your specific project needs.
