MaxZone Safe+® – Silica Dust Control System
Combating Respirable Crystalline Silica (RCS) Dust Exposure
Benetech’s MaxZone Safe+® is a patent-pending dust containment system that significantly reduces fugitive airborne dust, including up to 93% of Respirable Crystalline Silica (RCS) dust emissions in sample test reporting.
As bulk material travels through the system, fugitive dust is contained, captured, filtered, and chemically bound before it exits the MaxZone. Once the MaxZone Safe+® is installed and operating, the Dustinator® Plus air-filtering unit and MiniPak agglomeration unit run continuously and automatically.
The MaxZone Safe+® system consists of three proprietary Benetech technologies that work synergistically to contain, filter, and agglomerate fugitive airborne silica dust:
- CONTAIN: Its foundation is the MaxZone® Modular Skirtboard System. The MaxZone® effectively contains and seals load zones—reducing fugitive dust and preventing product loss and spillage, while improving material flow.
- FILTER: Installed at the tail end of the MaxZone is the Dustinator® Plus filtration unit. The Dustinator® Plus captures and filters a majority of the fugitive dust generated by the load zone.
- AGGLOMERATE: Finally, the MiniPak completes the entire system by administering a brief pulse spray that chemically agglomerates any remaining airborne dust from the Dustinator® Plus before the material exits the containment area.
The MaxZone Safe+® was developed under a Research Collaboration Agreement with NIOSH (National Institute for Occupational Safety and Health) and designed to meet MSHA-compliance standards.

How the MaxZone Safe+® Silica Dust Control System Works
The MaxZone Safe+® is a synergistic system of three Benetech technologies that combat silica dust exposure: (1) bulk material containment, (2) dry dust filtration, and (3) fine dust agglomeration.
- First, the MaxZone® modular skirtboard system securely contains bulk material as it drops onto the load belt.
- Second, mounted above the discharge end of the MaxZone®, the Dustinator® Plus functions as a dry dust collection system. The system utilizes an air blower system with a conveyor run signal that generates a powerful vacuum using four (4) micron filters removing nearly all airborne dust. Pressure differential controls determine when filters are near a dust saturation level and automatically activates a self-purge cleaning cycle, continuing until the filters are clear. This purge cycle cleans the filters and discharges the material back onto the belt.
- Third, just prior to the dry dust filter purge cycle, a solenoid valve on the MiniPak is activated. The MiniPak system administers a very brief burst of bio-degradable chemical binding agent during the purge cycle to agglomerate fine dust from the filter cleaning cycle, thereby removing up to 93% of silica dust emissions.
- The entire system cleaning cycle repeats as required, to maintain control of airborne silica dust.
Once the MaxZone Safe+® is installed and running, the self-purging air filtering system will continuously and automatically clear the filter debris while in operation. Differential pressure sensors monitor the air flow and automatically purge the filter system when needed.
