1. IceBox FCUs are not always supplied with
filters or frames. This is depending on the
order, please check the approved drawings
or contract our office if in doubt.
2. The filter frames are generally supplied as
galvanized steel frames unless otherwise
requested. It is internally lined with a
gasket. When the filter is compressed on
the gasket, it provides a seal for the filters
to minimize air from bypassing the filters.
Four metal clips are used on each side of
the filter frame to hold and compress the
filters on to the filter frame. Each clip shall
be properly engaged onto the filter frame
after each service of the filters.
3. There are the possibility of two standard
off the shelf filter frame sizes. One being
full size and the other in half size. These
standard sizes are widely used in the
general filter industry. The full size filter
actual dimension is 595x595mm while
the half size filter actual dimension is
290x595mm.
4. The synthetic fibre filter casing thickness is
47mm while the bag filter casing thickness
is 21mm with an extended surface bag
length of either 380mm or 530mm.
5. The synthetic fibre filter is disposable
type and needed to be serviced based
on operational requirement. The synthetic
fibre filter may deform over time requiring
replacement
6. A lack of maintenance might cause
clogging on the filter and will subsequently
reduce the AHU air flow rate.
7. The bag filter should be replaced in
accordance with the site requirements.
8. The bag filter is used to filter fine dust
that might not be visible through normal
vision. If not serviced regularly, it could
cause reduction in AHU air flow rate. If
not serviced for a period of time, the risk
of damage to the integrity of the panel
structure of the AHU due to high negative
section pressure created by the fan due to
clogged filters.
9. Filters should be monitored by an
appropriate device to determine when
replacement or cleaning is required.
10. The recommended final pressure drop limit
shall be 200Pa for synthetic fibre filter and
a limit of 300Pa limit for bag filter.
