Vapor Abrasive Blast Equipment EcoQuip 2 helps you expand your business with different applications. EcoQuip 2 can be used for concrete repair, coating removal, steel surface preparation and graffiti removal. The versatility of EcoQuip 2 is one of the characteristics that makes this equipment so remarkable. The best part is how easy it is to switch from one application to another. EcoQuip 2 is designed to accept any media heavier than water and has a blast rating of up to 12 bar (175 PSI).
Some might claim that their products are "dustless" or "dust-free," but the reality is there is no such thing. Sure, using a wet abrasive blasting machine will cut down on the plume of dust you get from dry blasting, but you're also left with a puddle of water. Make sure you understand the facts around dustless blasting. With Graco's EcoQuip 2 Vapor Abrasive blast equipment, you will see up to 92% dust suppression over dry blasting without the wet, slurry mess you get from traditional wet abrasive blasters.
Graco retained a third party to perform an Industrial Hygiene Survey in order to evaluate potential exposures to respirable airborne dust and respirable silica during three separate blasting operations. Blasting parameters were kept constant for the three scenarios with the exception of the blasting equipment used and the usage of water. Blasting was performed on a 4 ft x 4 ft slab of concrete using medium crushed glass abrasive.
Occupational exposures to airborne contaminants are evaluated by comparing them to Permissible Exposure Limits (PELs) and Short-Term Exposure Limits (STELs) established by OSHA. PELs are time-weighted average (TWA) concentrations for a normal 8-hour workday or a 40-hour workweek. STELs are 15-minute TWA concentrations that shall not be exceeded anytime during the workday.
Water and abrasive are combined in a pot under water pressure and then precisely metered into the airflow. When wet abrasive impacts a surface, the additional water weighs the particles down and creates a “dustless” effect.
The pools of water aren't left behind so there is less need to worry about toxic runoff.
