INTRODUCTION AND PRECAUTIONS
Intended Use
AAF Flanders AstroHood™Ducted HEPA Terminal Hoods ensure the delivery of cleanroom-quality
air to critical process applications, such as Pharmaceutical Manufacturing, Life Sciences, Biosafety,
Healthcare, and all other applications where clean supply air is a requirement.
User Responsibility
This document contains the information necessary to properly receive, assemble, install, operate,
and maintain the AAF Flanders AstroHood Ducted HEPA Terminal Hood equipment. The purchaser,
installer, and operator of the filter system MUST read and comply with this document in its entirety.
Failure to comply with the requirements of this manual may result in serious injury and void the
product warranty.
These instructions are specific to the AAF Flanders AstroHood S-l and S-ll units and incorporated
filters. All ancillary tasks including, but not limited to, electrical and mechanical work, equipment
handling, and safety procedures must be performed in accordance with industry-accepted practice
and all relevant local, state, and federal government codes, laws, and policies.
Before proceeding with installation, operation, or maintenance, review this Installation, Operation, and
Maintenance Manual in its entirety and all safety procedures with your company’s safety personnel.
Precautions
• Units must be properly transported and handled, since improper transport and/or handling can
result in damage , blemishes, or other imperfections.
• Deliveries are to be immediately inspected in the presence of the freight carrier to ensure
equipment is delivered in full and free from damage.
• The installation site must be suitable for unit installation.
• The supporting construction must be level, and the structure must have sufficient load strength to
support all equipment supplied.
• Mounting must be carried out by qualified and trained personnel in accordance with all local, state,
and national codes and regulations.
• Drilling through the unit and/or the use of fasteners, such as sheet metal screws, rivets, etc., to
secure the hood, as well as installation of field-installed trim, can compromise the integrity of the
supply hood by creating leak paths through the pressure boundary. Utilize only factory-approved
methods for suspending the hood from structural members located above the ceiling and
attaching field-installed trim.

Equipment Overview
The AstroHood™S-l & S-ll Ducted HEPA Terminal Hoods are a critical component to ensure filtration
system integrity and air cleanliness downstream of HEPA filters. The S-l unit offers a fully seal-
welded housing body with no penetrations of the pressure boundary. The S-ll unit employs full welds
downstream (clean side) of the HEPA filter and a riveted and caulked design upstream (dirty side).
Both the S-l and S-ll units are factory-pressure tested to 3” w.g. to guarantee a leak-free product is
supplied. These units may be installed in a variety of ceiling types, including T-bar ceilings and plaster
ceilings.
Both the S-l and S-ll units are available in either 304 Stainless Steel or Aluminum construction with a
variety of inlet options, top or side, and round or rectangular. Both units are supplied standard with an
aerosol injection & dispersion system, as well as static pressure/upstream aerosol concentration port.
The S-l unit is supplied with the industry-leading Energy-Saving Damper (ESD) which provides the
lowest operational pressure drop and, thus, energy savings, of any damper configuration available. Its
pressurized plenum design also leads the industry in airflow uniformity. The S-ll unit comes standard
with Guillotine damper, but Spilt Butterfly or ESD damper options are available.
All standard mounting and trim options are available: wire suspension, rod suspension, grid/T-bar
ceilings, and clean ceiling angles, along with permanent flange or field-installed trim, as well as a
variety of grille and insulation options.
AstroHood S-l & S-ll units are available in many configurations and sometimes are supplied custom.
Please reference order-specific data sheets and/or submittal drawings for more information.
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 packing material 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 a good fit.

Ducted Terminal Hood Installation
Install and support housing as instructed below. Housing installation must be accomplished in a
professional manner with flanges or trim properly sealed to prevent contaminant infiltration from the
interstitial space.
Inlet options are available as top or side, and in round or square/rectangular configurations. For side
inlets, damper options are limited to ESD and Guillotine. Flexible duct connections should be made
using stainless steel, worm-gear type draw bands (supplied by others) for maximum reliability. For
square/rectangular inlets, contractor is responsible for securing and sealing duct work to factory-
supplied blank flange. Examples of inlets shown below.
