OVERVIEW

Having Trouble Maintaining Negative Pressure? The BULLDOG® Negative Air Scrubber Pulls Contaminated Air Inward for Safer, More Controlled Work Zones

When air quality becomes part of the job, capacity matters. The BULLDOG® BD2KM from Abatement Technologies is a high-output HEPA negative air scrubber designed to move large volumes of air quickly while capturing the fine particles that come with restoration, renovation, and industrial work. It’s built for professionals who need dependable performance in bigger spaces and more challenging conditions.

On restoration sites, air can fill with dust, debris, and contaminants faster than most people expect. A powerful unit helps keep that under control. With 2,000 CFM of airflow, this system supports faster air turnover so crews can work in environments where visibility and particle levels stay more manageable. That’s especially helpful when demolition, drying equipment, or cleanup activities are constantly stirring things up.

There’s also the containment side of the job. Used as a ducted negative air machine, the BD2KM helps maintain negative pressure inside work zones. Air is pulled inward rather than escaping into surrounding areas, which helps limit the spread of mold spores, soot, or construction dust. It’s a practical layer of protection that supports cleaner adjacent spaces and more controlled working conditions.

In larger renovation areas, this level of airflow helps reach common air change targets without needing several smaller units. Fewer machines mean simpler setup, fewer power requirements to juggle, and less time spent managing filters across multiple devices. Crews can focus on the work instead of constantly adjusting equipment placement.

The filtration itself is just as important as the airflow. True HEPA performance captures extremely fine particles, down to 0.3 microns, which helps reduce airborne dust and improves overall site conditions. That makes a difference in environments where fine debris from sanding, cutting, or grinding tends to linger.

Another strength is flexibility. The BD2KM can run as a recirculating air scrubber to clean the air within a space, or it can be ducted to exhaust filtered air outside when negative pressure is needed. That adaptability makes it a reliable choice for projects that shift as they progress — something that happens more often than not.

From large residential losses to commercial renovations and industrial settings, a high-capacity HEPA negative air scrubber like the BD2KM helps maintain steady air movement and filtration throughout the job. It’s a straightforward solution for teams that need strong airflow, effective particle capture, and equipment they can count on day after day.

SPECIFICATIONS

FEATURES

• High-Capacity Airflow for Large Spaces
  One-horsepower, two-speed motor delivers up to 2,000 CFM on High and 1,300 CFM on Low, giving you the power to handle large containments, speed up air changes, and maintain steady negative pressure without relying on multiple smaller units.
  
  
• True HEPA Filtration With Multi-Stage Protection
  Two pre-filter stages plus a certified 99.97% efficient HEPA filter capture fine particles down to 0.3 microns, helping control dust, debris, and airborne contaminants during restoration, renovation, and industrial work.
  
  
• Built Tough, Yet Easy to Move
  Roto-molded BULLDOG® body components are made from UL94HB flame-retardant resin, creating a lightweight, highly durable housing that stands up to job site handling without adding unnecessary weight.
  
  
• Simple Mobility and Placement on Active Job Sites
  Four heavy-duty 4” casters — two fixed and two locking swivel — make it easy to move the unit between rooms, position it inside containment, and secure it exactly where airflow is needed.
  
  
• Smart Maintenance Features That Reduce Guesswork
  A built-in visual “change filter” indicator helps crews stay on top of filter performance, while the standard filter setup (polypad prefilter, pleated prefilter, and HEPA) keeps replacement and upkeep straightforward.
  
  
• Tested Safety and Flexible Filtration Options
  Independently NRTL certified to meet UL and CSA safety requirements, with optional 12” HEPA and high-capacity carbon filters available for projects that call for added particle or odor control.
