for GrindLazer Scarifers (25M860) The Graco 25M860 LazerVac 550 Vacuum System is a heavy-duty, gas-powered industrial vacuum engineered to deliver exceptional dust-collection performance for concrete surface-preparation professionals. Designed for large-scale scarifying, grinding, and marking-removal applications, the LazerVac 550 provides powerful suction, extended run time, and continuous dust containment — helping contractors achieve cleaner, safer, and more compliant jobsites.
This system is engineered to meet strict dust-control standards, reducing airborne silica dust when used with a scarifier, and is compatible with all Graco GrindLazer scarifiers as well as most standard scarifiers equipped with a vacuum port. To ensure suction remains strong throughout extended use, the system incorporates a dual-paddle, automatic filter-cleaning mechanism.
This feature continuously agitates dust from the filter surface while the vacuum is running, preventing clogging and maintaining optimal airflow. Coupled with the tool-less filter design, the LazerVac 550 provides dramatically simplified maintenance and eliminates the interruptions caused by traditional manual filter servicing routines. Dust enters the system through a built-in cyclone filtration stage, which pre-separates large particles before they reach the filter cartridges or engine housing.
This prolongs filter life, protects internal components, and ensures the system operates efficiently even under continuous heavy dust loads. For contractors working with aggressive cutters or grinding drums, this can mean the difference between a clean, productive workday and repeated equipment downtime. When used with a GrindLazer scarifier, Graco’s LazerVac 550 System uses contactor preferred

to provide 50% more vacuum pressure compared to LazerVac 330 to reduce airborne silica dust on larger scarifying jobs to help meet OSHA’s safety requirement for airborne silica dust. Longopac Bag System Continuous dust containment: The sealed Longopac bag system ensures captured dust is contained throughout the job — reducing dust exposure and potential cleanup time.
Large capacity, less downtime: The long-bag format allows for extended runtime before needing bag changes, which keeps crews working longer and more efficiently OSHA-Compliant Filtration: Safer worksites: The filtration meets regulatory requirements for silica dust control, helping you stay compliant with workplace safety standards. Reduced health risk: Captures fine dust particles, lowering risk of inhalation for workers and improving overall jobsite air quality Auto-Filter Cleaning Prevent clogging: A dedicated motor drives dual paddles that regularly knock dust off the filter while the vacuum runs — preventing clogs and maintaining suction levels over long jobs.
Consistent performance: Keeps airflow steady and reduces the need for frequent filter maintenance during operations. Durable Gas-Powered Honda Engine + Cyclone Filter Contractor-preferred power: A robust 13 HP Honda engine ensures dependable suction and performance under heavy load. Engine protection: The integrated cyclone filter system protects the engine from harmful dust and prolongs system longevity.
Tool-less Filter Design Quick filter changes: The toolless design allows for fast and easy filter replacement — minimizing downtime and keeping your crew on the job. User-friendly maintenance: Simplifies upkeep even on busy job sites, making the LazerVac 550 ideal for contractors who value efficiency.
