INTRODUCTION

The purpose of this document is to provide instructions for proper assembly and
maintenance of Solberg Scrubbers/Separators.

*WARNING*

This manual must be read and thoroughly
understood before using and maintaining your
scrubber/separator vessel. Failure to comply
could result in explosion, product/system
contamination or personal injury.

This manual should supplement the Operator’s knowledge of scrubber/separator vessel
maintenance. It is the responsibility of the Operator to interpret and explain all
instructions to persons who do not read or understand English BEFORE they are
permitted to maintain and service these vessels. This manual should be readily available
to all people responsible for Operations and Maintenance.

Thank you for selecting products from Solberg Manufacturing, Inc. We are confident
that our superior filter designs will exceed your application requirements.

2. Filtration Rules of Thumb

General: To ensure peak performance and delivered output from a compressor, blower,

turbine or engine, there must be clean and minimally restricted air/gas flow into the
equipment out of the equipment. Proper scrubber/separator filtration will eliminate
particulate, condensate and hydrocarbon mist from air/gas streams under extreme
conditions. Filter size is a critical component to minimizing restriction and maintaining
ideal operating conditions. With a properly sized filter, equipment will run efficiently
over its operating life.

A primary factor in filtration efficiency and size is air velocity through the filter media.
Generally, when velocity through a media is minimized, the filtration efficiency is
maximized. In this scenario, pressure differential/restriction across the filter is also
minimized. The primary objective when sizing a filter is to optimize the velocity of air
through the media (sometimes called face velocity).

Solberg’s filter designs are completed after analyzing and interpreting the Operators’
application specifications and requirements.

3. Filter Element Specifications

Media: CEG, PSG

 Efficiency: 99.97% @ 0.3 micron
 Typical Element Operating Differential Pressure: 0 – 5 psig / 0 – 0.36 BAR
 Filter Change-Out Differential: 2.5 psid / 0.17 BAR over initial backpressure of the

saturated element

 Typically used in oil mist coalescer/separator applications

Media: Polyester

 Efficiency: 99% @ 1 micron
 Typical Element Operating Differential Pressure: 0 – 3 psig / 0 – 0.21 BAR
 Filter Change-Out Differential: 1 psig / 0.07 BAR over initial backpressure of the

saturated and dirty element

 Typically used in scrubber applications to remove fine particulate and trace

condensate

Note: Filter change-out differential pressure is ultimately determined by the Operator.
Please follow application specific guidelines.

4. Element Cleaning

Cleaning is NOT recommended for Solberg Manufacturing’s scrubber or separator
elements. Once particulate entrainment and saturation occur, it is impossible to restore
elements to their original condition. It is recommended that once maximum differential
pressure is reached, new elements should be installed.

5. Vane/Demister Pack Specifications
Material: 304 / 316 Stainless Steel

 Efficiency: 99% @ 8 micron
 Typical Operating Differential Pressure: 0 – 1 psig / 0 – 0.07 BAR
 Used in scrubber applications to remove condensate and separator applications to

remove heavy concentrations of oil

 Designed to be removable and cleanable upon request

PROCEDURES

*WARNING*

Before installing any Solberg scrubber/separator, it
is essential that all packaging materials are
removed properly, to avoid injury risk.

1. Installation

A. Most scrubber vessels are designed in a “S” pipe configuration. In all cases the

bottom most connection of the vessel is the inlet

B. Flow direction is typically from the inside of the element to the outside of the

element

C. Ensure that pipe/flange connections are adequately sealed so the potential for

leaks is minimized

D. Mounting orientation is typically vertical to allow for gravity draining

E. Vessel should be anchored to ground prior to operation

2. Removing Vessel Lid

*WARNING*

Vessel must be relieved of pressure before
opening. Failure to comply with these instructions
could result in explosion or personal injury.

A. Remove fasteners (bolts, nuts and washers)

B. Swing lid to side of vessel using davit arm (if applicable)

3. Removing Element for Service/Maintenance

A. Element(s) are secured on a sealing plate and over a centering bracket with

fastening hardware (washer, nut and hex bolt).

B. Remove hardware and lift the element(s) out of vessel

*WARNING*

Failure to comply with these instructions may
result in system contamination.

4. Securing Element

A. Remove any dust or particulate present on element sealing surfaces prior to

installation. Place new element(s) squarely into the vessel over the centering
bracket to ensure the element(s) seat properly on the sealing plate

B. Place top plate (if applicable) on element

C. Secure washer, nut and hex bolt to the threaded rod of the centering bracket.

Element must be tightly secured, but DO NOT over tighten the hardware.
Consult with Solberg for a torque specification.

*WARNING*

Defective installation may cause bypass and
system contamination. Use only genuine Solberg
replacement parts.

5. Removing Vane/Demister Pack

A. Remove fasteners and retaining ring (when present)

B. The vane/demister pack will lift out of basket assembly

C. After cleaning, re-install by pressing pack into the basket assembly. Tighten

fasteners on retaining ring until secure

6. Securing Vessel Lid

A. Make sure all surfaces are free from dust and other particulate.

B. O-rings (when present) must rest evenly along the o-ring groove on the vessel

ring flange

C. Gaskets (when present) must rest flat and even along vessel ring flange

D. Install fasteners and tighten to torque specification supplied on drawing

MAINTENANCE RECOMMENDATIONS

1. Recording the initial differential pressure readings is recommended to effectively
maintain a scrubber/separator. Always document initial differential during start-up
when element is clean and after two weeks when element is dirty or saturated.
Replacement filters are needed when system experiences the maximum differential
pressure levels specified by the Operator. Refer to pages 4 and 5 for guidelines

2. Always check replacement o-rings/gaskets to insure they are seated uniformly along
the flanges during installation. If o-rings/gaskets do not seat properly or are
damaged, please contact Solberg Manufacturing, Inc. immediately

3. Always check inlets/outlet connections, sealing surfaces and hardware when
replacing the element to insure cleanliness. Wipe clean if necessary

4. Always ensure vane/demister pack is aligned and installed correctly within mounting
basket

5. Operate only when a proper seal exists

6. Never operate without absolute assurance that fasteners have been tightened to the
specified torque rating
