responsibility of the user to interpret and explain all instructions to persons who
do not read or understand English BEFORE they are allowed to maintain and
use this filter.
This manual should be readily available to all operators responsible for operation
and maintenance of the inlet air filters.
We thank you for selecting products from Solberg Manufacturing, Inc. We are
confident that our superior filter designs will meet your application requirements.

2. Filtration Rules of Thumb
General: For peak output performance from a compressor, blower, vacuum
pump, engine, or any other machine that consumes air, one must have clean,
unrestricted air. Proper filtration can help stabilize the working environment within
rotating equipment even when the external conditions may be quite severe. A
critical component in creating the right working conditions is filter sizing. With the
properly sized filter, equipment will run smoothly over its entire expected
operating life.
A major factor in filtration and filter sizing is air velocity through the filter media.
Generally, the slower the velocity of air through a media the higher the filter
efficiency and, conversely, the lower the pressure drop. Therefore, the primary
goal in filter sizing is to optimize the velocity of air through the media (sometimes
called face velocity).

Rule of Thumb #1: Always begin with the filter cartridge requirements when
sizing a filter. Once the appropriate element has been selected then move on to
the housing requirements.
Rule of Thumb #2: Always ask or specify a filter based on a micron rating with
filtration efficiencies. As an example, stating a requirement for a 1-micron filter
is misleading because no efficiency rating has been specified. A 1-micron filter at
95% efficiency may be less efficient than a 5-micron filter at 99% efficiency. For
proper air system performance in light and industrial duty environments, a filter
with a minimum of 99% filtration efficiency at 5 microns is required.
Rule of Thumb #3: Size your filter correctly by understanding the impact air
velocity through a media has on efficiency and pressure drop. Maintain the
suggested Air-to-Media ratios listed below based on the external environment
listings and Filtration efficiency needs.

Rule of Thumb #4: Pressure drop is also caused by the dirt holding capacity of
the element. As the element fills up with dirt, the pressure drop increases. It is
important to document the pressure drop across a given filter when it is new and
then clean or replace it when the pressure drop increases by 10” to 15” / 250-
280mm H2O over the original reading.
Rule of Thumb #5: The inlet connection greatly influences the overall pressure
drop of the filter system. To minimize the restriction contributed by an inlet filter, a
velocity of 6,000 ft/min (10200m3/h) or less is suggested through the outlet pipe.

4. Element Cleaning - Inlet Filtration
Solberg elements should be cleaned or replaced, once the pressure drop
reaches 15 to 20-inches water column (380 - 500mm WC) above the initial
pressure drop of the installation.
The decision to clean the element rather than replace it is left to the discretion of
the operator. Any damage which results from by-pass or additional pressure drop
created by element cleaning is the sole responsibility of the operator.

*WARNING*
The overall performance of a filter element
is altered once cleaned.
The initial pressure drop after cleaning will
be greater than the original, clean pressure
drop of the element.
After each subsequent cleaning, the initial
pressure drop will continue to increase.
Under all circumstances, the initial
pressure drop of the element needs to be
maintained at less than 20-inches water
column (500mm WC).
Cleaned elements that exceed 20-inches
water column (500mm WC) at start-up
should be replaced with new elements.
With many types of equipment, the maximum pressure drop allowed will be
dictated by the ability of the equipment to perform to its rated capacity. Under all
circumstances, the operator should avoid exceeding the manufacturer’s
recommended maximum pressure drop for their specific equipment.
A. Polyester Element: The polyester element may be washed in warm
soapy water, vacuumed, gently blown out or replaced. The element
should be dry before reinstallation. The element should be replaced after a
maximum of three cleanings.
B. Paper Element: The paper element may be lightly blown with low
pressure air. It is disposable and in most cases should be replaced with a
new element.
C. Activated Carbon Element: Not cleanable
If you are not confident that the integrity of the element was maintained during
cleaning, it is recommended that a new element be installed. Also, spare parts
such as gaskets, wing nuts and washers can be supplied upon request.

Section C
PROCEDURES
1. Installation.
A. Maximum operating temperature for most Solberg inlet air filter products is
220°F / 105°C. Temperatures in excess of this could cause damage to
elements, media and elastomers. High temperature products are
available.
B. Direction of flow is typically from the outside of the element to the inside of
the element. Most products have arrows indicating direction of flow on the
inlet and outlet ports.
C. Ensure that pipe/flange connections are adequately sealed so the
potential for leaks is reduced to a minimum.
2. Disconnecting canister top from canister base.
FS-(04, 05, 06, 07, 10, or 11): Twist top housing to open. Use care to
support bottom housing while removing top housing. Fitting damage can
occur if fitting is torqued in the wrong direction.

3. Removing element for service/maintenance.
A. Miniature Filter Silencer elements, models FS-(04, 05, 06, 07, 10, or 11),
should be free when housing tops are removed.
B. Clean sealing surfaces of housing and element so that they are free of dirt
or any other particulate.
*WARNING*
Failure to comply with these instructions
may result in system or equipment
contamination.
4. Securing Element.
Place new or cleaned element evenly in housing base. The wider end of
the element should be in line with the closing seam of the housing. Be
sure element seats properly in the housing base and there is no dirt or
particulate present on sealing surfaces. See Figure C.3.1.
*WARNING*
Defective installation may cause system or
pump contamination. Use only genuine
Solberg replacement parts.
5. Securing canister top to canister base.
A. Make sure all surfaces are free from dust and other particulate.

base.

Page 10
B. FS-(04, 05, 06, 07, 10, or 11): Reassemble housing top to base by
aligning tabs and turning into place.
6. Equipment Startup.
A. Be sure to read the instructions on installation or element replacement as
listed above before starting equipment.
*WARNING*
If at any time the operator is unable to verify
the integrity of the element or any housing
feature, the factory or a regional representative
should be contacted prior to start-up.
B. Please check the listed steps prior to startup.
1. Check element to make sure it is seated properly in housing
base. *WARNING*
Failure to seat the element properly may result
in contaminant by-pass resulting in damage to
equipment.
2. Check housing to make sure the housing top is properly
secured to base. See procedure 5 and Figure C.5.1 for details.

*WARNING*
If the air flow is reversed through a Solberg
filter unit, be sure to check the element and
housing internals for damage. Failure to do so
may result in damage to equipment.

MAINTENANCE RECOMMENDATIONS
1. Pressure drop readings are recommended to have an effective air filter.
Always document initial pressure drop during start-up when element is clean.
Replacement cartridge is needed when system experiences 10” to 15” / 250-
380mm H2O above drop above the initial reading. Refer to page 4 for initial
values.
2. Always check inlets/outlets, element base and its components when replacing
element to insure cleanliness. Wipe clean if necessary.
3. Operate only when a proper seal exists.
