Gasket Seal and Gel Seal Ducted, Disposable Ceiling Filter Modules
Gasket Seal Installation – TM-2 and TM-4
The TM Series Disposable Ceiling Filter Modules are unique
factory-assembled and tested units, incorporating a HEPA
or ULPA filter media pack, damper-diffuser, an optional
faceguard, and integral round duct connection. They are
made with an anodized aluminum housing that is
compatible with gasketed T-Bar ceiling grids.
1.
Before beginning installation of any HEPA or ULPA filter
module, the system should be cleaned and blown down
with both roughing filters and prefilters in place. This is
essential to minimize the initial quantity of particulate that
might be drawn into the filter modules.
2.
Carefully remove each bagged module from its shipping
carton just before installation. Remove the poly bag at the
point of installation and inspect the filter face for shipping
damage. Carefully scrutinize each unit before installation.
Avoid accidentally damaging the delicate filter media while
handling the filter. (Gloves are recommended to comply
with some protocol requirements.)
3.
The TM-2 and TM-4 units are equipped with four hanger
support points for independently suspending the
modules. Local codes, rigidity of the ceiling system,
or owner preference will determine the use of hangers.
These hangers are available only on the gasket version.
4.
AAF Flanders recommends that the modules be sealed
airtight against the ceiling grid. This may be accomplished
by using pressure-sensitive gasketing, caulking, or
non-hardening tape sealant. This is a design decision,
dependent upon room performance requirements.
5.
When connecting the flexible round duct to the module
collar, avoid excessive slack in the duct. Where practical,
set the housing in place, then connect the round duct to
the collar. Drawbands must be positioned below the
dimples in the collar to prevent slippage or blowoff of
the duct connection. Stainless steel, wormgear-type
drawbands are recommended.
Gel Seal Installation – TM-2 and TM-4
TM-4 Disposable Ceiling Filter Modules are unique
factory-assembled and tested units, incorporating a
HEPA or ULPA filter media pack, damper-diffuser, optional
faceguard, and integral round duct connection. They are
made with an anodized aluminum housing that is
compatible with gel seal grid systems.
1.
Before beginning installation of any HEPA or ULPA filter
module, the system should be cleaned and blown down
with both roughing filters and prefilters in place. This is
essential to minimize the initial quantity of particulate that
might be drawn into the filter modules.

the point of installation and inspect the filter face for
shipping damage. Carefully scrutinize each unit before
installation. Avoid accidentally damaging the delicate filter
media while handling the filter. (Gloves are recommended
to comply with some protocol requirements.)
3.
Inspect the knife edge seal around the perimeter of the
module for damage.
4.
Set the module down into the gel seal grid. Check to be
sure the knife edge on the module penetrates into the gel
in the channel on all four sides to form an airtight seal. No
latches are required. The weight of the module sets the
unit into the gel seal grid.
5.
When connecting the flexible round duct to the module
collar, avoid excessive slack in the duct. Where practical,
set the housing in place, then connect the round duct
to the collar. Drawbands must be positioned below the
dimples in the collar to prevent slippage or blowoff of
the duct connection. Stainless steel, wormgear-type
drawbands are recommended.
