Operation and Maintenance Manual –KAF duct housing with particulate filter

1. INTRODUCTION
The purpose of this Operation and Maintenance Manual is to familiarize the
user with the intended use, design, operating principle, installation and
operation of the product.
2. INTENDED USE
KAF duct housings are designed for installation in rectangular ventilation duct
systems. The units are installed in systems supplying air to aseptic rooms such
as operating rooms, laboratories, advanced electronics or optics
manufacturing facilities, etc. KAF housings do not replace the inflow ceilings
or inflow openings with particulate filters within the ventilation system,
however, they permit the extension of the operational lifetimes of the filters in
these devices, constituting an initial filtration component. An additional
advantage of using KAF housings is the possibility to install them outside of
clean rooms. Therefore, replacing the filter within the KAF does not cause
contamination of the room or the necessity to shut it down.
3. TECHNICAL DESCRIPTION
Execution –housing
The KAF housing has a galvanized steel body painted to RAL 9010 white.
On both sides, the body ends with flanges for connection of rectangular
ventilation ducts. One of the body walls has a tight inspection cover mounted
with the use of M5 screws with 4 mm hex sockets. Inside the housing there is
an H13 class air filter in accordance with PN-EN 1822. The filter is mounted with
4 set screws with a 4 mm hex socket. There are measuring nipple fittings
installed in the duct housing, permitting supervision of the contamination level
of the filter with the use of a differential pressure gauge. It is recommended to
use the differential pressure gauge for the optimum operation of the diffuser.
The KAF housing is optionally equipped with components for the inspection of
integrity/mounting of the filter and execution of tracer-gas leak tests.
The construction of the KAF allows the use of test methods in accordance
with ISO 14644 Cleanrooms and associated controlled environments –Part 3:
Test methods.
Execution –air filter
The filter is classified as H13 according to EN 1822: 2009, in a casing made of
galvanized steel with an 8 mm flat gasket, made of high quality neoprene.
Verification of the filter pollution level is possible using a differential pressure
switch (not supplied) connected to the spigots mounted in the box casing. It
is recommended to use the differential pressure gauge for the optimum
operation of the diffuser.

Guidelines for designing
KAF duct housings should be placed in such a way so as to permit easy
opening of the inspection cover and air filter installation/removal.
For proper operation of the unit, the recommended airflow velocity through
the H13 class 150 mm filter should not excess 0.75 m/s, and for the 292 mm
filter –1.5 m/s.
Final airflow resistivity: 500 Pa. The maximum operation temperature 70 °C.
It is recommended to replace the air filters when the pressure drop measured
at the filter in use exceeds twice the value of the pressure drop declared for
a new filter.
4. INSTALLATION CONDITIONS
The filter should be delivered to the installation site in its original cardboard
box. The filter can be grabbed by the frame only, it is forbidden to touch the
filtering package even if the filter is equipped with a protective mesh.
Before placing the filter, remove the inspection cover and then remove the
set screws by turning anticlockwise all the way so that the filter can be placed
freely.
Installation of the filter into the duct housing is done by carefully gripping the
filter frame and pushing it in through the inspection hole until it has touched
the thrust profile on the housing wall. Next the four set screws should be
tightened evenly to ensure a tight connection of the filter; usually 3 full
revolutions of each of the four screws are enough once the gasket has
touched the thrust frame.
When installing the air filter, special attention must be paid not to damage
the gaskets. After the installation, carefully check the tightening of the filter
mounting screws in the setting seats, and the inspection cover. These
operations are to avoid any leaks.
A 4 mm hexagonal wrench is required for mounting/dismounting the filter and
the inspection cover.
