Air Scrubber / Negative Air Machine

63 modèles

Fonctionnement

A blower draws room air through the filter stack; HEPA media captures 99.97 percent of particles at 0.3 microns and carbon adsorbs odors and VOCs. Ducted out of a sealed containment, the same machine becomes a negative air machine, holding the workspace below ambient pressure so contamination cannot escape.

Types et variantes

Air Scrubber: Filtration unit with HEPA and carbon stages that cleans particulate and odor from air.
Patient Isolation Systems: Negative-pressure enclosures used to isolate spaces in healthcare settings.

Comment choisir

Air changes per hour (ACH) drive machine count: target ACH times room volume, divided by unit airflow. Restoration and mold work commonly targets 4-6 ACH; healthcare and abatement containments follow their governing protocols. Filter loading is monitored — capture falls as filters blind.

Normes et certifications

IICRC · S520: Standard for professional mold remediation, including containment and air filtration.
ASHRAE · Standard 62.1: Ventilation and indoor air quality guidance referenced when conditioning occupied spaces.

Questions fréquentes

What is the difference between an air scrubber and a negative air machine?

Configuration of the same machine. Recirculating in a room, it scrubs; ducted out of a sealed containment, it creates negative pressure that keeps dust and spores inside the work zone.

How many scrubbers does a space need?

Enough combined airflow to hit the target air changes per hour — room volume times target ACH, divided by 60, gives the required cfm, split across units.

What do patient isolation systems add?

Sealed anteroom-and-envelope structures with HEPA-filtered negative pressure, converting standard rooms into isolation spaces during surges and renovations in healthcare facilities.
