PharmaGel ™
Ducted Supply Ceiling Module with
Replaceable HEPA Filter

Designed for Pharmaceutical and Biotech Applications
The AAF PharmaGel HEPA filter ceiling module is ideal for
applications requiring an easily replaceable HEPA filter cartridge
without risk of bypass leakage. An AAF gel sealant pocket ensures
airtight integrity at the filter to module seal.
The PharmaGel module was designed with the pharmaceutical and
biotech industries in mind. Filter cartridges can be tested and replaced
without disturbing the module housing. The removable stainless steel
perforated grill allows easy wipe down of the modules to prevent cross
contamination of the product. Stainless steel trim is also available.
Welded Aluminum Housing
The airtight housing is constructed of sturdy (0.063) aluminum.
Joints and seams are welded and sealed.
Vertical or Horizontal Airflow
PharmaGel modules can be used for vertical or horizontal airflow
applications. Horizontal flow must be specified when the modules
are ordered to include bottom-edge filter supports.
Designed for Tee Grid or Plaster Ceiling
Each housing includes an integral aluminum flange on the downstream
side, for use with a conventional T-bar grid system. Optional stainless
steel trim is available for mounting in a plaster ceiling.
Stainless Steel Perforated Grill
The flush-mounted protective grill is constructed of 22-gauge stainless
steel with a perforated design and 40% open area. Four stainless steel
washers and acorn nuts hold the grill in place.
Adjustable Butterfly Damper
The round top inlet, 10" standard, is designed with a butterfly
damper conveniently operated from the downstream, or room side,
using a rotary-type mechanism. A perforated diffuser plate beneath
the damper promotes even distribution of air across the filter.
High Efficiency
The AstroCel ® II, 2 7/8" HEPA filter, featuring a 2" deep pack and
mini-pleat design, provides the lowest pressure drop in the industry
with optimum air cleaning efficiency. Filters with 3" and 4" deep packs
are also available.
Easy Testing
A static pressure port adjacent to the installed filter cartridge is
provided for easy measurement of the resistance across the filter,
or to serve as an upstream aerosol sample test port.

Gel Seal Prevents Bypass Leakage
Gel Seal Forms Airtight Seal
AstroCel II filter cartridges
designed for PharmaGel modules
each include a pocket of AAF gel
sealant around the perimeter of
the filter on the downstream side.
When the filter is installed, a knife
edge on all four sides of the
housing penetrates the channel
of gel to form an airtight seal.
With the gel sealant pocket
located on the downstream side
of the housing, there is no dead
air space commonly found in
competitive products that seal
on the upstream side.

AAF gel sealant in a pocket along the
perimeter of the AstroCel ® II filter
cartridge forms an airtight seal.

Sturdy Retainers Protect the Filter
The filter cartridge is held in the
housing by four retainers, each
located on a threaded stud,
which also support the protective
grill. To replace the filter cartridge,
the retainers are simply turned 90
degrees. The filter retainer studs
are designed to avoid penetrations

and eliminate potential leak
paths. The retainer mechanism
is also designed to prevent the
knife edge from bottoming out
in the gel track.
