EQUIPMENT OVERVIEW
The AstroHood™S-lll RSR Ducted HEPA Terminal Hood is a low-profile and lightweight, ducted
room-side replaceable HEPA/ULPA filter terminal module of anodized aluminum construction using
a gel seal minipleat or separator-less style filter pack. The Astrohood S-III RSR unit is designed to
provide unidirectional airflow when installed in drywall or T-bar ceilings. AstroHood S-III RSR modules
are available in three nominal sizes: 24”x24”, 24”x36”, and 24”x48”, for either 1-1/2” or 2” T-bar, and
with 8”, 10”, 12”, or 14” diameter inlet collars.
The filter pack is sealed in an anodized extruded aluminum frame with integral gel seal channel to
ensure an air-tight seal. The filter’s extruded aluminum center divider is furnished with a port for
in-room baffle plate adjustment, and for measuring of an upstream challenge aerosol and static
pressure. AAF Flanders does not recommend using the aerosol port as a means of aerosol injection.
The one-piece hood/inlet collar is made of spun aluminum, and the inlet collar is ribbed to secure the
flex duct retaining strap. A 22-gauge, 40% open area removable perforated grille protects the media
pack. Hanging holes (1/8" in diameter) are drilled on the module’s top four corners to secure seismic
restraint wires or to hang the unit.
Unpacking
• Carefully remove the unit from the shipping carton and inspect for any damage that may have
occurred during transportation. Two workers minimum are required to lift the unit from the
container.
• Remove housing from shipping carton and inspect for concealed damage and any hardware that
may have become loose in transit.
• Remove the Grille and Field Installed Trim, if supplied, and set aside. It is good practice to label or
mark the grille and trim components to match with the respective unit to ensure good fitment.
Installation
Install and support housing as instructed on the following pages. Flexible duct connections should be
made using stainless steel, worm-gear type draw bands for maximum reliability. Housing installation
must be accomplished in a professional manner with flanges or trim properly sealed to prevent
contaminant infiltration from the interstitial space.

Mounting Options
Unit can be suspended by wire via four (4) 1/8" holes, one (1) located in each corner.
Flange (Permanent Trim) for Grid / T-Bar Ceiling
The AstroHood™S-III RSR unit is installed from the top side of the suspended ceiling grid/T-bar with
the integral flange resting on the grid/T-bar. If no gasket is present in the ceiling grid, the AstroHood
unit should be sealed to the grid using RTV (Dow Corning 732 or GE 102 is recommended).
1. Thoroughly clean the mating surfaces of the unit flange and ceiling grid to remove any debris or
residue that may inhibit an adequate seal.
2. Apply a continuous, small bead (~ ¼" diameter) of RTV to the mating surface of the grid/T-bar.
3. Center and lower the AstroHood unit into the opening and seat the unit onto the grid/T-bar. Apply
uniform pressure to ensure the flange is bonded to the grid/T-bar (see Fig. 02).
4. Remove excess RTV.

PermaFrame for Hard/Gypsum Ceilings
The PermaFrame provides a support structure and room-side finish trim in one piece. It is supplied
with predrilled mounting holes located on the vertical flanges that are used to easily level and anchor
the frame to customer-supplied studs above the ceiling structure. Manufactured of 18-gauge cold-
rolled steel or stainless steel, the welding on all exposed corners guarantees a smooth, cleanable
surface. White powder coat paint is supplied as standard finish. The PermaFrame is ordered
separately from the AstroHood™unit.

Filter Unpacking, Installation, Storage, and Operation
Unpacking
• Before removing the filter module from the carton carefully read the removal and handling
instructions printed on the outside of the carton.
• AAF Flanders cleanroom filters may come packaged in suitcase-style cardboard sleeves. If so,
simply reach into the box and grab the pre-punched handles within the insert.
• If the filter is in a cardboard liner, the filter must be oriented so that the open ends of the liner are
facing outward (i.e., to your left and right rather than upward). Carefully cut the packing tape that
holds the filter in the liner. Always check for torn or deflected liner edges. If any are found, straighten
or flatten such edges prior to liner removal to prevent media damage.
• One person should carefully hold the plastic bag(s) while the other person carefully pulls the liner,
sliding it away from the filter.
• Panel filters will be single- or double-bagged (depending on customer requirements) with snug-
fitting cardboard liners. Ducted filters will be single- or double-bagged and packed in reinforced
cartons.
• The filter should be handled with extreme care to avoid contact with the media and/or face screen.
• While the bag is still present, carry the filter by grabbing the bag. Be careful to keep the filter away
from your body and any objects in your path.
- If the bag is not present, always handle filter by the frame, avoiding contact with the media and/
or face screen.
• Remove the bag carefully. Avoid bringing hands and fingers into contact with the filter media.
• Additional precautions for gel seal filters:
- Care is taken at the factory to prevent the bag from contacting the gel. Be very careful when
unpacking gel seal filters by removing the bag slowly and carefully.
- If the bag comes in contact with the gel, pull the bag off the gel slowly. Quick removal of the bag
may cause damage to the gel and possible separation of gel from the gel channel.
Grille Installation and Removal
The standard grille is removable and made of 40% open area 316L Stainless Steel, but painted cold-
rolled steel is available. Grille mounting can be supplied as standard four (4) corner acorn nut design.

Filter Unpacking, Installation, Storage, and Operation (cont’d)
Installation
• Carefully lift the filter into place, inserting it into the housing and taking care to make certain the
knife edge is properly seated into the fluid gel seal. NOTE: Setting filters properly requires two (2)
people.
• Rotate each of the four (4) filter retainers, one (1) in each corner, into place and hand-tighten the
hex nuts.
• Install the grille using the four (4) acorn nuts or ¼-turn fasteners [haven’t mentioned this ¼-turn
fasteners option previously] with the hinged grille option.
Storage
• Location: Storage should be indoors, (under roof and enclosed) and absolutely protected from
moisture.
• It is strongly recommended that the storage space be climate-controlled.
- Temperature Limits: Maximum temperatures of 250°F (121°C) intermittent, and 100°F (38°C)
steady state. Minimum temperature is 32°F (0°C).
Operating Conditions
• Temperature: The maximum operating temperature is determined by the filter configuration.
- Consult the filter submittal drawing for the specific maximum operating temperature.
• Humidity: 100% relative humidity is acceptable. However, condensation must be avoided to
prevent degradation of performance and potential filter failure.
• Filters should not be operated in caustic or acidic environments.
• Filters should not be operated in excess of twice the rated performance for flow rate or pressure
drop.
Static Pressure/Upstream Aerosol Ports
Filter must be supplied with centerboard and port to sample upstream aerosol and to measure
upstream static pressure. A filter with centerboard and port is also necessary to access damper
adjustment (filters ordered separately).

Butterfly Damper for wider adjustment of airflow
from roomside. This option includes a fixed
distribution plate and swagged inlet. Dampers in
the HVAC system are recommended.
Fixed Distribution Plate for applications where
no adjustment of the airflow is required from the
roomside and all are in the HVAC system.
Adjustable Distribution Plate for fine tuning
the airflow from roomside. Dampers in the HVAC
system are recommended.
Fig: 06 Dampers and Operation
Insulation Options
Insulation options are available to prevent heat loss, mitigate potential condensation, and/or provide
sound attenuation. Determining the use of these options is the responsibility of the design engineer.
The 2" foil-backed option is an aluminum foil-backed fiberglass (installed 6.0 R-value) attached to
the housing using adhesive-mounted insulation anchors and caps.
Dampers and Damper Operation
The AstroHood S-lll RSR Ducted HEPA Terminal Hood is supplied with Split Butterfly, Telescoping
Disc, or no damper (i.e., fixed distribution disc).
The Split Butterfly and Telescoping disc dampers are adjustable from the room side via Phillips head
screwdriver. Please note that a filter with centerboard and access port must be supplied to access
the damper adjustment.
