Instructions for AmerKleen Filter Retaining Frame
and Disposable Glass Filter Pads

These retaining frames may be installed just as you would install a
permanent metal impingement filter; however, the frame should be
positioned with the hinged pins on the front grid pointing downward.
This is to ensure that the grid will remain in the proper position when
the front grid is opened. It is not necessary to remove the retaining
frame from the installation when replacing media since the hinged
grid allows fast and easy pad replacement. However, for convenience
or other reasons, the retaining frame my be removed from the
installation and the pads replaced at a remote location.

Installing Pads

The normal procedure for servicing these industrial disposable glass
fiber pads is to remove the pad from the retaining frame and replace
with a new pad. When installing the new pad, check to ensure it is
installed in the proper direction of airflow. With AmerKleen filters,
the air-leaving side of the pad is dyed green for easy and positive
identification of proper direction of airflow. Due to the progressive
density construction from the air-entering to air-leaving side of these
pads, the life of the filter will be substantially shortened if it is installed
in the reverse position.

The air-entering side of the non-color coded pads can be determined
by inspection of the filter. Fibers on the air-entering side will be more
loosely woven than on the air-leaving side due to the progressive
pack media.

How to Install

The hinged grids have pins on all four corners to engage and hold
the pad in place once it is properly installed. This prevents sagging
of the pad or leakage of unfiltered air around its edge from vibration
or heavy dust loading.

The “rotation” replacement method is suggested for larger installations.
With this method, a number of cells are replaced at intervals rather than
attempting to service the entire installation at one time. This ensures a
more uniform air supply by maintaining an average resistance across
the filter.

1. Center media on retaining
frame as shown above. Check
that the media is installed in the
proper direction of airflow.

2. Tuck the media behind the
flanges to ensure the proper
air seal.

3. Close the front grid and secure
the latch. The filter is installed
and ready for service.
