Connecting the ductwork
Type TFP pharmaceutical clean room terminal fil-
ters are available with different spigots:
Top entry circular spigot
Side entry circular spigot
Side entry circular spigot, removable
TFPs with circular spigots are fitted with a lip seal
and fit onto circular ducts to EN 1506 or EN 13180.
Connect the duct in such a way that the connection
is tight.
To protect the filter once installed as much as pos-
sible from excessive contamination, proceed as fol-
lows when you install the ventilation system:
Keep the ducts clean when you install them.
If you have to interrupt the installation proce-
dure, protect all openings from the ingress of
dust.
If necessary, clean the ducts before you com-
mission the ventilation system.
Commissioning
General information
Before you start commissioning:
Check that the filter casings are correctly
seated.
Remove protective film, if any.
Ensure that all filter casings are clean and free
from residues and foreign matter.
Prime the ventilation and air conditioning
system for 24 hours before you insert the filter
element.
Volume flow rate balancing
To adjust the ventilation and air conditioning
system, you first have to carry out volume flow rate
balancing for each pharmaceutical clean room ter-
minal filter. Volume flow rate balancing is required
before initial commissioning.
