Blasting Dust Collector Applications

Abrasive Blasting Dust Collection

At A.C.T. Dust Collectors, we understand you need the right abrasive blasting dust collection system in place to handle your filtration and meet your current application and long-term needs. We’ve got the experience and history to meet the demands of your abrasive blasting operations. We design, engineer and manufacture new industrial dust collectors to help you blast correctly, efficiently, on time and below budget. Ensuring the safety of you and your employees is critical. Our Nano-Elite filters remove 99.9% of the particulate from the air stream. The cleaned air is then directed to the location of your choice, either returned to the facility or exhausted to the environment.

We’ve been offering the ultimate in air solutions for more than 20 years; you can count on us to fulfill your dust removal needs. We can assist with application questions, drawings, layout, and product customization. Custom designed and built systems are common, and our engineering team can help you find the right dust collectors for abrasive blasting. Call us today at 763-557-7162.

GRANITE BLASTING Dust Collection

Activities such as grinding, cutting, routing, drilling, chipping, or polishing granite and other stone materials containing crystalline silica can create airborne dust. These types of activities are conducted by companies such as stone countertop manufacturers and granite monument/headstone manufacturers. The silica dust particles created by these activities can cause the potential for health hazards to workers. OSHA regulations state that employers must protect workers from hazardous dust levels and particles that may be generated from the blasting material, and no employee is to be exposed to an airborne concentration of silica in excess of the PEL of 50 μg/m³ calculated as an 8-hour TWA (total weight average).

A.C.T. Dust Collectors has dust collection equipment to fit your granite blasting application needs and help clear the air, creating a healthier and safer working environment. Please contact us to discuss your needs.

Blasting Dust Collctor Application FAQs

What size dust collector do I need for an abrasive blasting operation?

The right abrasive blasting dust collector is sized based on airflow (CFM), the size of the blast enclosure, the type of blast media, and the amount of dust generated. An undersized system may allow dust to escape, while an oversized system can increase energy costs and reduce efficiency. A properly engineered dust collection system provides consistent airflow, extends filter life, and maintains clear visibility throughout the blasting process. Because every operation is different, the best system is one designed around your specific application and production requirements.

What filter media works best for abrasive blasting dust?

Abrasive blasting applications require durable filter media that can withstand constant exposure to fine, abrasive particles. High-efficiency cartridge filters are commonly used because they capture fine dust while maintaining strong airflow. Features such as abrasion-resistant inlets and pulse-cleaning systems also help extend filter life by preventing excessive dust buildup. The best filter media depends on the blast material, particle size, operating schedule, and dust loading, so selecting the right combination helps reduce maintenance and maintain consistent dust collection performance.

What OSHA and NFPA compliance standards apply to granite and abrasive blasting dust collection?

Abrasive blasting operations must comply with strict OSHA permissible exposure limits (PEL) and NFPA regulations for combustible dust. When blasting granite or stone, OSHA enforces a PEL of 50 micrograms per cubic meter ($50 \ \mu\text{g/m}^3$) over an 8-hour time-weighted average to protect workers from hazardous crystalline silica dust.

Additionally, many blast media dusts or coatings removed from parts are combustible. To comply with NFPA standards, the dust collection system may require safety features such as:

• Explosion isolation valves
• Explosion venting panels
• Fire suppression systems

How do I know when my abrasive blasting dust collector needs maintenance?

Routine maintenance helps keep your dust collection system operating efficiently and prevents unexpected downtime. Common signs that service may be needed include:

• Reduced airflow or dust capture
• Poor visibility inside the blast room
• High differential pressure readings
• Frequent filter replacements
• Dust accumulating around equipment or work areas

Regular inspections of filters, ductwork, fans, and pulse-cleaning components help identify issues early and keep the system performing as designed.

Should I install my blasting dust collector indoors or outdoors?

The choice between an indoor or outdoor installation depends on your facility's available floor space, noise tolerance, and compliance requirements.
