OVERVIEW

Trouble Keeping Dust and Contaminants Contained? This HEPA-AIRE® Negative Air Scrubber Creates Strong Negative Pressure for Cleaner, Safer Workspaces

The HEPA-AIRE® H1990M from Abatement Technologies is a professional-grade negative air scrubber designed for projects where airflow, containment, and filtration truly matter. When you’re managing a restoration site, renovation zone, or active work area, keeping contaminated air from spreading isn’t optional — it’s essential. This unit is built to handle that responsibility without overcomplicating the setup.

With a rated output around 1,600 CFM, it delivers the kind of airflow needed to maintain steady negative pressure in medium-to-large containments. That steady pull helps keep dust, spores, and airborne debris from escaping into adjacent rooms or occupied spaces. In practical terms, it means the air stays where it should, and the work zone stays controlled.

This HEPA negative air scrubber also helps crews reach typical air-change-per-hour targets in larger areas. In spaces around 16,000 cubic feet, it can provide roughly six air changes per hour — a solid range for mold remediation, water damage restoration, fire cleanup, and renovation work. Air cycles out consistently, and contaminants don’t have time to linger.

Filtration is where this system quietly does its most important work. True HEPA performance captures 99.97% of particles down to 0.3 microns, including mold spores, fine construction dust, and fibers that would otherwise stay suspended in the breathing zone. High-capacity prefilters help extend filter life under heavy conditions, which matters when a jobsite stays active for days or weeks at a time.

You’ll often see a negative air machine like this used across different environments — restoration containments, renovation projects, healthcare areas, and even manufacturing spaces where dust or particulate control is needed. It can be ducted outside to maintain pressure, or used for high-rate recirculating filtration when full containment isn’t required.

There’s also a practical advantage to the 1,600 CFM size. It’s large enough to handle whole-room or multi-room setups, yet still portable enough to move as the job progresses. Many crews find that one unit at this capacity can replace several smaller machines, which simplifies power management, placement, and filter maintenance.

At the end of the day, this system is about control and consistency. It helps maintain negative pressure, supports clean airflow, and keeps contaminants contained while work moves forward. For contractors and facility teams who need dependable performance without constant adjustment, the HEPA-AIRE® H1990M delivers exactly what’s expected from a serious HEPA negative air scrubber.

SPECIFICATIONS

FEATURES

• Two-Speed Airflow for Better Jobsite Control
  Choose between 1,600 CFM on high for large containments and aggressive air movement, or 1,050 CFM on low for smaller spaces and more sensitive environments. This flexibility lets you maintain proper negative pressure and hit target air changes per hour without oversizing equipment.
  
  
• True 99.97% Certified HEPA Filtration
  The deep HEPA filter captures 99.97% of particles down to 0.3 microns, including mold spores, fine dust, fibers, and debris. Even after long run times, the filter maintains strong performance, helping you keep contaminants contained and air cleaner throughout the project.
  
  
• High-Performance Motor & Custom-Engineered Blower
  Built for demanding restoration and construction environments, the powerful motor and blower are designed to move large volumes of air consistently. This helps the HEPA-AIRE® Negative Air Scrubber maintain stable negative pressure and reliable airflow during extended operation.
  
  
• Compact, Portable Design That Fits Tight Spaces
  Weighing about 125 lbs with filters installed, the unit is sturdy yet manageable for jobsite movement. Its narrow cabinet design makes it easier to position in corridors, mechanical rooms, and other tight containment areas where space is limited.
  
  
• Durable Steel Cabinet Built for Tough Conditions
  The 20-gauge galvanized steel housing with watertight pop rivet construction is made to handle rugged use. An integrated 12" exhaust collar allows quick duct connection for negative pressure setups or controlled air discharge.
  
  
• Safety-Tested & Easy to Maintain
  Independently NRTL-certified to meet UL and CSA safety standards for peace of mind on active worksites. A swing-out hinged door with cam latches allows fast filter access and replacement, helping reduce downtime and keep the negative air machine running efficiently.
