Portable Air Scrubbers Negative Air Machines

Why use Scrubber Technology?• Air Scrubbers capture

potentially harmful or irritating dust, odors, spores and other contaminants from the air during the job.

• Air scrubbers are essential when working in areas where occupants cannot leave (hospitals, healthcare, office buildings)

Occupied structures require the use of air scrubbers:

• Hospitals• Nursing Homes• Apartments – other units are occupied.• Homes – residents stay during renovation work.• Office Buildings – business must continue.• Schools – surrounding classrooms.• Hotels – guests in surrounding rooms.

Typical Applications for PAS units.

• Mold Remediation

• Water Damage Restoration

• Fire Restoration

• Bio-Hazards (death scene)

• Crime Scene (tear gas)

• Sewer Back-up (black water)

• Chemical Spills

• Fuel Oil Spills

• Manufacturing processes

• Welding

Typical Applications cont’d

• Restoration/Remodeling/

Construction Activity– Paint odors

– Drywall dust

– Tile installation & removal

– Granite counter-top

– Sanding

– Grinding

– Carpet removal & installation

How do we achieve this?

• Mechanical Capture of Particulates– Filtration

– 99.97% HEPA Filtration

• Adsorption of Vapors & Gases– Carbon

Particle Size Range in Microns

• 99% of all airborne particles are smaller than 1 micron in size.

• Smaller than 1 micron are considered “Lung Damaging” as they are respirable (small enough to penetrate the nose and upper respiratory system and deep into the lungs).

Particulate Pre-filters

• Coarse particulate pre-filters capture particles 50-100 micron size

• Pleated particulate 2” filters capture visible particles (> 10 micron)

Microscopic Particles Need

H.E.P.A. Filtration(High Efficiency Particulate

Air)

HEPA Filters

• 99.97% efficient @ 0.3 micron size.

• Abatement Technologies’ HEPA filters individually tested and certified.

• Most efficient filter available.

What is Carbon or Activated Charcoal?

• High quality carbon is manufactured from coconut shells.

• Traps and holds odors inside granular surfaces.

• Safe workplace environment, unlike working in high levels of ozone.

Using a Portable Air Scrubber3 ways:

• Recirculation Mode

• Negative Pressure

• Positive Pressure

Recirculation Mode

• Unit located inside and exhausts inside the work environment.

• Cleans air by pulling particulates and odors through filters.

• Target 5+ Air Changes per Hour (ACH) for optimum cleaning.

Negative Pressure (unit inside containment)

• Unit located inside the work environment and ducted to outside the work area.

• Pulls contaminants into unit and exhausts clean air to another location.

• Creates negative pressure inside work area.

• Keeps contaminates inside workspace.

Negative Pressure Diagram

Positive Pressure

• Unit is located outside of work space & air is fed into work environment

• Uses outside air to supply clean air to work space

To Determine How ManyAir Changes Per Hour are Needed

• ACH =Air Changes per Hour

• CFM = Cubic Feet per Minute

• Room Air Volume = Length x Width x Height

• ACH=machine cfm x 60 min/hour

Room Air Volume (length x width x height)

Example

ACH = 800 cubic feet/min x 60 min/hr

30’ x 40’ x 8’

ACH = 48,000 cubic feet/hr = 5 ACH

9,600 cubic feet of space

Sizing Your Air Scrubber

Cubic Feet of work space x ACH / 60 min

Example:

1800 sq. ft. structure with 9 ft tall ceilings.

5 ACH needed.

16,200 cubic ft x 5 / 60 = 1350 cfm unit

Are PAS & Neg Air Machines the same?

Yes & NoBoth feature:

-HEPA filters.

-Negative pressure & recirculation mode.

-Durable construction.

PAS units also feature:– Multiple stage pre-

filtering (3-4 stages)– Light weight– Upright design– Low amperage

requirements– Daisy chain feature

available on most units

One-person transport!

What is a Negative Air Machine?

• Designed for asbestos and lead abatement.

• Can recirculate air or create negative pressure.

• Minimal pre-filtering• 99.97% HEPA

H1990HP

Typical Asbestos Job• Unit inside the

containment area.• Ducted to outside to

create negative pressure.

• Runs continuously to assure no asbestos particles leave the jobsite.
