explosion, product/system contamination
or personal injury.

Section A

INTRODUCTION

The purpose of this manual is instruction on the proper assembly and care of
Solberg inlet air filters.

*WARNING*

This manual should be used as a supplement to the user’s understanding of the

proper care needed to maintain a safe and dependable air filter. It is the
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” / 250­280mm 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 ft3/min (10200m3/h) or less is suggested through the outlet pipe.
The table below lists the suggested flows based on pipe size:

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.

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*

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. Polyurethane Prefilter: The prefilter may be washed as a sponge or

replaced to give the element a longer service life.

D. Epoxy Coated Wire Mesh and Stainless Steel Wire Mesh Elements:

Cleaning instructions similar to polyester, except mild solvents may be

used.
E. Activated Carbon Element: Not cleanable
F. Polypropylene Element: Cleaning instructions similar to polyester
G. Nomex Cloth Element: Cleaning instructions similar to polyester

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.

Figure C.2.1: Housing top removal.

Lift

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.

A. Remove housing top by loosening hex nut/ or wing-nut and lifting off.

3. Removing element for service/maintenance.

A. Carefully remove retaining hex nut/ or wing-nut and washer over top plate,

and then remove element.
B. Clean sealing surfaces of housing, top plates and element end caps so

that they are free of dirt or any other particulate.

*WARNING*

4. Securing Element.

A. Place new or cleaned element evenly on base plate. Be sure element

seats properly on base and there is no dirt or particulate present on

sealing surfaces. With multiple element stacks place elements in line with

base element and ensure elements seat properly.
B. Place top plate on element by centering on tap bolt.
C. Secure washer and hex nut to top plate and tap bolt. Element must be

tightly secured. Note: Do NOT over tighten!

5. Securing canister top to canister base.

A. Make sure all surfaces are free from dust and other particulate.
B. Replace cover. Feed threaded bolt into corresponding bolt holes and

secure with washer and hex nut. Note: Do NOT over tighten!

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.

Failure to seat the element properly may
result in contaminant by-pass resulting in
damage to equipment.

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.

6. Equipment Startup.

A. Be sure to read the instructions on installation or element replacement as

listed above before starting equipment.

*WARNING*

B. Please check the listed steps prior to startup.

1. Check element to make sure it is seated properly on element
base or sealing surface.

*WARNING*

2. Check element top plate or cover to make sure it is seated
properly on element.

3. Check housing cover that it is installed correctly onto housing.

4. Be sure all fasteners and hardware have been tightened.

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” / 250­380mm 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.
