Safety Precautions
Always use safe and common sense precautions when working with Air-Care
equipment. Do not block walkways with equipment. Remove delicate and
breakable articles from the immediate work area. The following are precautions
that should be reviewed by all persons who will be involved in the cleaning activity.
•Other than the 3 filters, there are no user serviceable components in the Air-Care
Sentinel Air Scrubber. Only trained technicians should attempt to make internal
repairs on this equipment.
•Always turn off the main power switch on the control panel, or disconnect the power
before opening or removing the top or removing the filters from the Sentinel.
•Be sure all power cords and electrical extensions are rated to meet or exceed the
original Air-Care power cords (12 gauge), and inspect all AC power plug to be sure
the Ground Pin is in place.
•Never connect power to Air-Care equipment unless all covers, and safety shields are
in place. Mechanical and electrical parts could activate and cause injury.
•Never allow anyone except a properly trained technician to use the equipment or/and
cleaning products.
•All Air-Care equipment is designed for US standard 115 volt, 60 Hz AC. Most Air-
Care equipment can be special ordered to meet other worldwide standards for a
reasonable price and delivery schedule. Always check the specifications on the
equipment before connecting electrical power to Air-Care equipment. The Sentinel
1500 can be special quoted for 220 Volt 50 Hz but may have reduce performance or
incur additional costs to provide the same performance as the 60 Hz model.

Air Scrubbers,
When and How to use them
Briefly, an Air Scrubber circulates ambient air through its filter system, usually 3 stages
with a HEPA final stage, and exhausts clean air into that environment. It is a BIG air
purifier. Sometimes, the air scrubber may also contain activated carbon filters to adsorb
odors and chemicals that may be in the ambient air.
A Negative Air Machine pulls in ambient air, filters it (just like the air scrubber) and has
a means to exhaust it outside of the building, or at least outside of the “Contained” part of
the building. Carbon Filters may be employed in the Negative Air Machine, also. The
Negative Air machine may be located outside of the contained area with a hose to
transport air out of the contained area.
The same type machine often performs these 2 functions, so it may be a little confusing at
times. It’s like saying you will “Uncork” a bottle with a “Rubber Stopper”. “Cork”
originally defined a “Cork Stopper” before “Rubber Stoppers” were invented, so the
nickname “Cork” applies more to the function of the device than the material from which
it is made. Air Duct Vacuums (Collectors) can also perform “Air Scrubber” and
“Negative Air Machine” functions. I will try to use the correct term in the context of
each function, but remember that the terms are somewhat interchangeable. The term
refers to the function accomplished with a particular configuration that provides the
desired airflow more than it applies to a specific piece of hardware.
When should you consider using one or more of these devices? There are only a few
universal regulations or standards, but to say it is all guesswork is not at all true. On a
construction site where large amounts of fine dust are generated, it would be expected
that the workers would be wearing eye protection as well as some type of respirator to
protect their lungs. If the site was adjacent to an office with a full staff, it would be
unthinkable to start the work without a temporary barrier of plastic sheeting to prevent
the dust from covering the occupants and the office equipment. If the dust was
potentially toxic and the particles were too small to be seen by the naked eye, even more
protection for both the workers and the adjacent occupants would be required. This is the
basic reason, it is necessary to filter the air in the work area, and to put that contaminated
area in a “Negative Pressure” condition. areas.
Once the contaminated areas are defined, a remediation plan can be created to contain the
contamination. Putting up Plastic walls, building an air lock, sealing off the supply and
return ducts, and installing negative air machines is next. Remember that Containment
walls and access door control the contaminated air paths, but the room pressurization
controls the direction and amount of that flow. Containment design as well as Negative
Air Machine and Air Scrubber size and locations must be considered together to match
the needs of each project. The scope of this manual will only discuss the Containment
structures in very general terms. There are many sources for containment construction in

got General Particulate control as well as the much more stringent Mold and Asbestos
protocols.
Pressurization must be maintained at a minimum of .02” of W.G. between the area of
Mold Growth and the uncontaminated area. If spores have spread to other areas of the
building, that area needs to be cleaned and isolated, but it should NOT be in the same
containment area as the primary growth area. Since this secondary area only has spores,
and not growth, it will be in a separately contained area. This means you will have 3
ZONES, 1) is Very Contaminated, 2) is Contaminated, and 3) is Clean or
Uncontaminated.
To prevent contamination of the other areas, Zone 1 will need to be “Negatively
Pressurized” first. The HEPA filtered Air will be exhausted from Zone 1 with a negative
air machine with enough capacity to provide a minimum of 4 air changes per hour. The
pressure drop should be measured between this room and Zone 2, and also Zone 3. It
should be .02” W.G. between 1 and 2 and .02” W.G. between Zone 2 and 3. Measuring
from Zone 1 to Zone 3 should find .04” W.G.
The pressure drop should be maintained at .02” W.G. between a contained and an
uncontained area. This can be measured with a simple manometer. It is rugged, easy to
setup, and inexpensive (around $50), so if it does get damaged or contaminated, it is not a
major loss.
The size and number of machines depends on the volume of the space being contained as
well as how “Loose” the containment is. If a containment structure lets a lot of air in the
doors and joints, it will require more than the theoretical “minimum”. As a starting point,
calculate the square footage of the room or rooms, multiply by the ceiling height, and
remember that if this area has a common ceiling plenum, you must attach the
containment walls to the ceiling deck above the drop ceiling tile grid. It is generally
recommended to have a minimum of 4 air changes per hour in the work area. To convert
this requirement to a CFM spec for the Negative Air Machines, multiply the Volume of
the work area by 4 changes/Hour then divide by 60 Minutes/Hour.
Or simplified,
Length x Width x Height x 4 = cfm
60

So, a room that is 15 feet wide by 40 feet long with an 8-foot ceiling would require a
negative air machine with:
If that room had a common ceiling return plenum, making the ceiling deck 11 feet high,
then:
Now here is the tricky part, what if the drop is NOT at the minimum? The air should be
flowing from outside into the Clean Zone (3), then from Zone 3 to Zone 2 (slightly
Contaminated, and finally into the most contaminated Zone 1. If the containment is not
well sealed or the Door flaps between zones pull open with the airflow, you will need to
increase the CFM or reduce the airflow into the area. Remember, the recommended air
exchange rate is from 4 to 12 air changes per hour.
If this area requires a higher-pressure difference, you may need to go as high as 12
changes per hour, which means you would divide by 5, which gives us 1320 cfm for the
same area that required only 440 cfm if it were tighter.
As the filters become loaded, the effective cfm will drop slightly, so be sure you have a
little more capacity than the minimum. By the same token, if you have too much
capacity, it is possible to pull down the containment walls, with potentially disastrous
results.
15 x 40 x 8 = 320 cfm

To achieve balance on an actual job, it may be necessary to use multiple negative are
machines, and it may be necessary to use a negative air machine in Zone 2 to exhaust
clean air out outside.
Once the air flow is in the correct direction, and the pressure drop between clean, sort of
dirty and really dirty are balanced, it may still be necessary to add an air scrubber inside
the work area for either the main remediation Zone due to dust and debris from heavy
construction work, or in the Intermediate Zone where the building contents are being
cleaned to assure the level of contamination does not become greater than it already is.
An Air Scrubber is often used under a cleaning table fitted with a wire mesh top. The
Technicians use HEPA vacuums to clean the objects from the room on top of the screen
so that any contaminate that would potentially become airborne will be pulled down into
the air scrubber and captured. While it is running, it is filtering the room air, and
constantly removing any particles that have become airborne as the contents of the room
are being moved from place to place to be cleaned.
It may seem a bit overwhelming at first glance, but the methods developed for containing
airborne Asbestos fibers during 35 years of abatement, are well proven and easily
adaptable to the current need to protect workers and occupants from airborne mold spores
and hyphae.
To review the use of Air Scrubbers and Negative Air machines. They are required when
a contaminated area or the contents of an area are contaminated with mold, asbestos, lead
or any other potentially dangerous airborne substance. The Negative Air Machine must
be matched with the Containment Structure to provide outside air to flow from the
cleanest area to the slightly dirty and finally the Most Dirty area where the HEPA filtered
Negative Air Machine will pull in Contaminated air, filter it, and discharge it outside the
containment area. The difference in pressure between contained areas must be at least
.02” W.G. between each, and the airflow must provide between 4 and 12 air changes per
hour.
Air Scrubbers may be required to circulate and filter the air within one or more of the
contaminated areas to be collect contaminates as they are released into the air, as well as
making certain there are not “dead spots” in the contained area where there could be a
contaminate buildup.

Maintenance
When to Change Filters
It is impossible to predict EXACTLY when filters must be changed
The Pressure gauge on the Panel will provide a guide. For this test, the Inlet
must be open, without the Restrictor Plate. When the Air-Care Sentinel is first
installed at a new location, turn it on and note the reading on the pressure gauge
(usually 3.0 to 3.5). Next block the 12” inlet with a piece of cardboard and again
note the meter reading (Usually 4.8 to 5.0).
While operating, the pressure gauge should ALWAYS remain at least 0.6” WC
LOWER than the Blocked reading (usually 4.0 to 4.4). Another indication that
filters need to be changed is when the pressure gauge reads more than 1” WC
HIGHER than the initial reading when the inlet is fully open (Usually 3.0 to 4.5).
The NORMAL pressure reading with the 4” dia. Restrictor Plate installed is 4.4.
When planning the number of pre-filters to have on hand for a job that involves
heavy demolition with significant dust and debris in the area, the change cycle
could be:
First Pre-filter: every 3-4 hours, (2” white)
Secondary Pre-filter: every 14 Hours, (1/4” white)
HEPA every 800 hours (33 days at 24 hr/day).
It is also advisable to thoroughly decontaminate the Air scrubber after each job and
start each job with a clean set of filters.
