1.6 Assembly – General Comments
As indicated previously, the individual components that will comprise
the filtration system may ship separately and will be required to be
installed on site. The SAAF PORTA-Scrubber is a self-contained
product and, consequently, a minimum amount of assembly is
required. Refer to section 3.0, Installation Instructions, of this manual
for further detailed instructions. Consult with an experienced installer
to obtain an accurate estimate of the time, personnel, and equipment
resources and tools that will be required to complete the assembly
and installation of the filter system. Site assembly will be limited to
moving and lifting individual components, screwing components
together, and caulking. The PORTA-Scrubber weights and dimensions
can be found on the product drawings. Packages of the chemical
media will typically have a maximum weight of approximately 50
pounds (23kg). Particulate filters will typically weigh less than the
chemical media filters.
1.3.3 Particulate Filters: The standard particulate prefilter will be
AAF PolyKlean Blue pads. Depending on the size of the PORTA-
Scrubber ordered, a round 24" diameter x 2" deep or a round 37"
diameter x 2" deep may be supplied. PolyKlean Blue 2" deep
filters are individually packaged.
Note that other optional or special filter arrangements may be
supplied depending on the requirements of the project. Check

AAF or by others, consult the documentation specific to these
products for appropriate instructions.
2.0 Principles of Operation
An understanding of the design and operating principle of the
PORTA-Scrubber with chemical media is useful for effective
installation, operation, and maintenance. The system is intended to
remove corrosive and odorous gaseous contaminants from sewage
pumping stations, laboratory vent hoods, and pressure relief valves
of chemical storage tanks.
WARNING: Chemical tank on other high concentration applications
may require constant airflow and other special operating instructions.
Ensure that the design operating instructions are followed.
The heart of the system is the SAAF chemical media. The PORTA-
Scrubber is a small high density polyethylene (HDPE) vessel that
allows air to move across the chemical media bed in an upward
direction. The method of contaminated removal is through physical
adsorption or a combination of physical adsorption and chemical
reactions, such as oxidation. AAF offers a variety of impregnated
and un-impregnated dry granular chemical filtration media to handle
a wide range of contamination problems. For more information on
AAF’s gas phase air cleaning products, contact your AAF
representative.
The SAAF PORTA-Scrubber is one of the various systems designed
to support the SAAF chemical media in the air stream and to allow
easy installation, operation, and maintenance of the system.
CAUTION: All dry chemical media has the potential to generate
a small amount of dust in the exhaust. If your scrubber will be
located indoors without external exhausting, you will require
additional particulate filtration on the exhaust. Solutions can range
from an additional PolyKlean Blue pad downstream of the media
bed to a separate filter box.

3.1 Space Requirements
A minimum of 24" clear space must be available around the
PORTA-Scrubber to perform routine maintenance. Additionally,
it is recommended that 36" clear space be available in at least
one direction. Additional space may be required for inlet and
outlet ductwork.
3.2 Foundation, Supports, and Anchoring
The foundation and/or supports must be designed to be
adequate to support the filter system operating weight, and any
seismic, live or other load requirements (if any), with a sufficient
factor of safety as determined to comply with the requirements
of all applicable governing codes, standards, and laws. Ensure
that the foundation or support surface is level and smooth
before proceeding. The filtration system may be designed for
operation in either indoor or outdoor locations. Indoor
applications may require additional particulate filtration. The
equipment is not specifically designed to resist and operate
under unusual dynamic loading situations such as high winds or
earthquake conditions. If the equipment is required to function in
such circumstances special precautions may be required to
ensure that the equipment will remain intact, anchored and
functioning. If this situation applies consult with a qualified
professional engineer before installing the equipment.

3.4.2 Locating, Mounting, and Supporting the PORTA-
Scrubber: Position the PORTA-Scrubber in its final installation
location. The support surface under the base of the frame shall be
level, smooth, clean, and dry. The location shall not be subject to
standing water or flooding. The circumference of the tank base
shall be fully supported. Adjust the supports so that the base is
level in all directions.
Provision for the anchoring hardware, support cradles, or any other
supporting component will be the responsibility of the installer
or others. These items will not be supplied by AAF unless noted
specifically in the AAF quotation and in the accepted customer
purchase order.
3.4.3 Connection of inlet and outlet ducts: Inlet and outlet ducts,
when required, shall be connected to the inlet and outlet faces of
the housing as shown in figure 4.
WARNING: The housing is not designed to support the weight
of the inlet and outlet ducts. All ducts shall be supported
independently of the housing. Any attempt to support the ducts
from the housing may result in serious equipment damage and
severe personal injury.
3.4.4 Sealing the inlet and outlet duct connections: A flexible
coupling with stainless steel clamps is provided. All other provisions
of the inlet and outlet ducts, the connecting hardware for the inlet,
and the gaskets or caulk will be the responsibility of the installer
or others. These items will not be supplied by AAF unless noted
specifically in the AAF quotation and in the accepted customer
purchase order.
Caulk generously, between the flanges of the connecting ducts
and the housing to prevent air leaks. Any caulk used shall be a long
life, flexible, non-drying caulking material. The caulk supplier shall
ensure that the caulk shall meet the customer specifications for the
application in which it is being used.
CAUTION: Many installations prohibit the use of certain caulking
materials such as Silicone. The use of materials containing VOCs
should also be avoided as they may have a negative effect on the
life of the gas phase filters.
3.4 General Filter System Installation
3.4.1 Installing the PORTA-Scrubber: Keeping the PORTA-
Scrubber on its shipping pallet, move it to its final installation
location. Remove the plastic wrapping and straps that secure
the PORTA-Scrubber to its pallet.
WARNING: The tank lid will not support the weight of the unit. Any
attempt to support the unit from the tank lid may result in serious
equipment damage and severe personal injury. Do not walk on the

Step 3: Place the perforated screen
on the PolyKlean Blue pad.
Step 1: Start with the tank empty
and the HDPE grating exposed.
Step 2: Place the PolyKlean Blue
pad on the HDPE grating.
3.5 Preparation for filter installation: In order to maximize
the life of the chemical filters and the particulate filters, it is
recommended that filter installation be the final installation task
before start-up and commissioning of the system. In preparation for
filter installation, it is recommended that the following be completed:
• Completely clean the system to remove all construction debris
and dirt, sweep and vacuum to remove visible dirt.
• Finalize and complete all caulking in the system.
• Finalize and complete all painting in the system.
It is recommended that all cleaning materials and paints used in the
system be free of solvents. If this is unavoidable it is recommended
that sufficient time be allowed for complete drying to occur and for
the VOCs to disperse before installing the filters. This process can
be accelerated by “blowing down” the system; i.e., operating the fan
without the filters to ventilate the system. Consult with your AAF
representative to obtain an appropriate product. Also, before
“blowing down” the system, check that it is safe to operate the
fan without the pressure load of the gas phase chemical filters.
Consult the AAF submittal drawing for pressure information.
3.6 Prefilter Installation: A PolyKlean Blue filter pad shall be used
to prevent the build up of dust, grease, and water on the gas phase
chemical media.
Install the prefilters as shown in the sequence shown below.
For best results AAF recommends the use of the 2" thick PolyKlean
Blue filter media. Circular PolyKlean Blue pads will be cut with a
2" overlap.
Equipment Size PolyKlean Blue Replacement Pad
Part Number
PS-200 358-012-024
PS-500 358-012-037
Remove the polypropylene perforated screen from the bottom of the
tank. Place the PolyKlean Blue pad directly onto the HDPE grating
at the bottom of the vessel. Ensure there are no gaps between the
filter pad and the side wall of the tank. Place the polypropylene
perforated screen on the PolyKlean Blue pad.

3.7 Installation of Media in the PORTA-Scrubber
There are several varieties of chemical media. Each media is designed to remove a specific
contaminant, or group of contaminants. The arrangement of media in the scrubber is significant.
Media bed #1 is located closest to the inlet. Review the drawing and ensure media is being placed
in the correct bed.
Respirator masks, chosen in accordance with the safety instructions found in the MSDS for the
chemical media, are required to be worn by all personnel during the media installation process,
as well as all other personal safety equipment listed on the MSDS.
Installing Media by Carton:
Loosen latch and remove top hatch. Gradually pour the media in a controlled manner. Avoid causing
significant impact loading by gradually metering the media into the PORTA-Scrubber. Media should
be filled no higher than 4 inches from the tank lid.
3.8 Latches on Tank Cover
Place the cover on the PORTA-Scrubber tank and latch the cover as shown.
WARNING: All electrical work has the potential to cause shock,
injury, and even death. Disconnect all power whenever working on
the system. Only qualified electrical personnel should work on the
system at any time.
Provide an appropriate power supply as specified in the submittal
information.
CAUTION: Use of the incorrect line voltage may result in irreparable
damage to electrical components.
3.9 Fans
Sometimes the PORTA-Scrubber may be supplied with an externally
mounted blower. See the AAF drawing for information and details.
Blowers can be fitted with an optional power cord with a 115-volt plug.
CAUTION: All electrical work must be carried out in accordance with
all appropriate governing electrical codes and standards.

5.4 Disposal of Used Filters
Used chemical filtration media and particulate filters shall be
packaged and disposed of in full accordance with all required and
applicable laws and regulations. Consult with local environmental
control authorities such as local, state, and federal EPA & OSHA
authorities for direction. Material Safety Data Sheets (MSDS) are
available on all products supplied by AAF. Contact your AAF
representative for further information.
5.5 Cover Lid Sealing Gaskets
The proper maintenance of the cover lid sealing gaskets is critical to
the performance of the system. Check the gaskets carefully whenever
the gas phase chemical filters are replaced. If gaskets are worn,
frayed, or damaged in any way they should be replaced. Check the
seal between the lid and the tank whenever new SAAF chemical
media is installed.
5.6 General System Maintenance
Ducts, external PORTA-Scrubber surfaces, latches, blower, and
other system infrastructure should be checked at least every 6
months. Internal surfaces shall be examined whenever filters are
replaced. Examine all components for the following:
5.6.1 Cleanliness: Sweep and vacuum all standing dust or dirt in
the system. If using cleaning solvents, be mindful of the impact of
solvents on the performance and life of the chemical media and
take appropriate precautions to protect the system.
5.6.2 Water: The system should be completely dry at all times.
The presence of standing water, condensation, or dampness is
detrimental to the performance and life of the system. Determine
and remove the cause for the presence of water in the system, dry
the system, and examine all components for the presence of molds
and other biological growth. Remove all contamination, clean and
sterilize as necessary.
5.6.3 Filter System Integrity: Ensure that the unit contains the
appropriate filter elements, both particulate and gas phase, and
that these elements are correctly installed. Check for missing or
improperly installed components and review the system seals.
Check for air leaks at joints and seams and replace gaskets,
worn hardware, and seal with caulk as necessary.
5.6.4 Duct and System Integrity: Examine the entire system to
ensure that contaminated air cannot leak around the filter system.
Check all perimeter seals and repair as necessary.
5.6.5 Corrosion: If metal components are corroded repair the
corrosion and provide protective coatings as necessary. Be mindful
of the impact of painting on the performance and life of the
chemical media, and take appropriate precautions to protect the
system. Determine the source of the corrosion and rectify.
4.0 Start-Up Instructions
Immediately on start-up, examine the filter system for any apparent
air leaks or other anomalies. Air leaks may be detected by noise
or by use of a synthetic smoke puffing device at the external joints
and seams of the filter system installation. Correct or repair any
discrepancies, as necessary. Repeat this examination after
24 hours of operation and again after one week of operation.
5.0 Maintenance
5.1 PolyKlean Blue filter: A PolyKlean Blue pad has been included
as part of the system. Under normal conditions, the filter can be
expected to last for between 10 and 12 months before reaching
its final recommended capacity loading (see the AAF drawings
for details). However, this may vary under heavier or lighter
particulate loading conditions. At an air velocity of 75 feet per
minute the 2" deep PolyKlean Blue pad can be expected to have
an initial pressure drop in the range of less than 0.1" water gauge.
The recommended final pressure drop is 1.0 in. w.g.; however, it is
recommended that the PolyKlean Blue pad be replaced whenever
new chemical media is installed.
5.2 Chemical Media Monitoring
A discussion of sophisticated chemical media monitoring is beyond
the scope of this manual. At its most simple, when the system is
used to remove nuisance odors, the time to change out the chemical
media is when the odor begins to be regularly detected on the clean
side of the system. In more stringent applications, active real time
electronic and passive coupon corrosion monitoring systems are
available to determine the performance of the system. The remaining
life of the media can be determined by taking a sample of media and
returning it to AAF for analysis. Consult with your AAF representative
regarding active and passive monitoring systems and media sampling
for remaining life analysis.
5.3 Removal and Replacement of Particulate and Gas Phase
Chemical Media
Before removing activated carbon media, it is recommended the
media bed be grounded to release any electrostatic discharge.
Removal of filters will be the reverse of the installation process
described earlier in this manual. Filter and media replacement
will be carried out exactly the same as at initial installation detail with
use of manual or pneumatic methods. Reference appropriate safety
precautions related to specific gases being handled at the facility
and any operation instructions developed during the design phase
of the project.
