OSHA TABLE 1 COMPLIANT DUST SUPPRESSION FOR HEAVY-DUTY CORING

When you're deep into a concrete coring operation or making long runs with a cut-off saw, maintaining constant water pressure is non-negotiable for silica dust compliance and blade longevity. This M18™ SWITCH TANK™ system replaces the fatigue of manual pumping with a battery-driven dual diaphragm pump, ensuring a steady stream of up to 60 PSI. The modular design is a game-changer for heavy civil crews; you can swap out the water supply tank for a sprayer assembly in seconds without cross-contaminating your lines. With the 5-mode pressure regulator, you can dial in the exact flow needed to meet OSHA Table 1 requirements while maximizing your water usage on the slab, delivering up to 40 tanks per charge on the M18 platform.

  • / Instant, Constant Pressure up to 60 PSI for optimized cooling and dust suppression during high-torque coring and cutting.
  • / Modular SWITCH TANK™ Design allows for isolated pump, hose, and tank assemblies to prevent cross-contamination between fluids.
  • / Dual Diaphragm Pump engineered for increased durability and longer service life in demanding jobsite environments.
  • / Wide-Mouth Opening and integrated strainer prevent debris from clogging the pump during field refills from non-potable sources.
  • / OSHA Table 1 Compliant solution when paired with appropriate concrete cutting and drilling equipment for silica dust management.
