Air Scrubbers & Negative Air Machines
Yes.
KDT provides HEPA air scrubbers and negative air machines, set up as clean-air units for shelters, trailers and offices or as negative pressure for mold and contamination work, with filters changed on schedule.
Typical configuration
- Airflow
- About 500–2,000 CFM per unit (typical), variable speed
- Filtration
- Pre-filter, HEPA (99.97% at 0.3 micron), optional activated carbon for odor
- Negative pressure
- Ducted exhaust, commonly targeting about -0.02 in. w.c. (-5 Pa) across containment
- Sizing
- Commonly 4–6+ air changes per hour for clean air; more for remediation
- Power
- 120 V, about 2–8 A per unit
- Monitoring
- Manometer or differential pressure monitor on negative air setups
An air scrubber pulls room air through a pre-filter, a HEPA filter and often an activated carbon stage, and pushes clean air back out. Run inside a room, it cleans and recirculates the air. Ducted to the outside from a sealed work area, it becomes a negative air machine: it pulls more air out than leaks in, so dust, spores and contamination flow into the work area instead of out of it.
After floods, they hold negative pressure on mold and demolition work so the rest of the building stays clean. On hazmat sites, they help control dust and particulates in containment and decon areas.
KDT sizes units to the room volume and the air changes you need, sets up ducting and poly containment, checks pressure with a manometer, and changes pre-filters and HEPA filters on schedule. Spent filters from mold or hazmat work are bagged and disposed of as that kind of waste.

Questions, answered.
Does KDT provide air scrubbers and negative air machines?
Yes. We supply HEPA air scrubbers and negative air machines, set them up for clean air or containment, and change filters for the length of the incident.
What's the difference between an air scrubber and a negative air machine?
It's often the same machine. Run inside a room, it scrubs and recirculates the air. Ducted outside from a sealed area, it creates negative pressure so contaminants can't escape.
How many air scrubbers do I need?
Multiply room volume by the air changes per hour you want, divide by 60 to get CFM, then divide by the unit's rating. A 1,000 sq ft room with 8 ft ceilings at 6 air changes needs about 800 CFM.
