User manual Neoflux® quick-cleaning magnetic filter 5
General
This manual contains information for the correct operation and maintenance of your device. It also
contains instructions for avoiding possible injury and serious damage and it allows a safe and as trouble-
free functioning of the product as possible. Read this manual thoroughly before putting the device into
operation, familiarise yourself with the operation and control of the device and follow all instructions
precisely.
•The data published in this manual is based on the available information at the time of delivery.
This is issued subject to later amendment.
•We retain the right to amend or modify the construction and/or model of our products at any time
whatsoever without any obligation to modify any previously supplied products accordingly.
Ferromagnetism
The working principle of the device rests on (Ferro)magnetism.
Ferromagnetism is the basic mechanism by which certain materials such as iron cobalt and nickel can
get magnetized when exposed to an externally applied magnetic field. Materials that remain magnetized
after the external magnetic field is removed, are called permanent magnets. Most magnetic materials
lose their magnetism after the external magnetic field is removed. Most alloys of iron, cobalt and nickel
are magnetic. However, some stainless steel alloys like AISI304 or AISI316 are only slightly magnetic.
Because in most cases it will be Fe parts that will be Ferro-magnetically influenced, we will use the term
‘Fe’ in this user manual when we mean ferromagnetic material

Safety
User manual Neoflux® quick-cleaning magnetic filter 10
Danger of magnetic field
The magnets generate a powerful magnetic field that strongly attracts ferromagnetic (Fe) materials.
Always take into account that these materials may suddenly be drawn towards the magnet, very
powerfully. This applies to steel workbenches and steel tools, but also to Ferromagnetic materials
carried on your person, such as coins in your wallet or your keys. Make use of non-magnetic tools and
workbenches fitted with a wooden worktop and preferably a non-Fe frame (for instance stainless steel).
Always be aware that Ferromagnetic parts will be attracted -- even personal items - if you are
closer than 0.3 meter to a magnet.
Danger - strong magnetic field!
People fitted with pacemakers should on no account enter the magnetic field
(within a radius of 1 meter).
Prohibited for people with pacemakers!
Credit cards, chip cards, computer disks/tapes, computer screens, watches,
etc. may be damaged or destroyed if they enter the magnetic field (within a radius of 0.5 meter).
Danger for magnetic cards!

Device description
Intended use / user indications
Products
Suited for separation of ferromagnetic* (Fe) particles out of fluids and powders under pressure, grain
size up to 0.5 mm, such as flour, sugar, soy, spices, plastics, etc.
Not suited for products that are too sticky and/or badly flowing or raw materials with particle size over
0.5 mm.
Fe particles
Suited for use in product flows with Fe particles of 30 µm and larger, dependant on magnet type.
See product specifications for exact values.
Product has to be free of Fe parts or other parts that can cause damage to the magnet bar tubes with
low wall thickness (like dents/bumps). Mechanical sieving is advised when necessary.
When filtering of even smaller or soft-magnetic (like SS) Fe particles is required, then this can be
achieved by even more powerful Neoflux® magnets!
Temperatures
Suited for product temperatures up to ….°C or higher, or up to 200°C with special high temp magnet
material, dependant on magnet type. See product data sheet for exact values.
The magnet is to be protected against higher temperatures than prescribed, because the magnet might
lose magnetic force permanently when exposed to high temperatures
Free space
Make sure that there is enough free space around the magnetic filter to perform and ease the cleaning,
inspection and maintenance operation, and for mounting / dismounting of the magnet bars. See also the
added drawings in the appendices.
Pressure
Operating pressure in the product channel has to be less then … bar.
Testing pressure …. bar.
See product data sheet for exact values.
Noise level
---
Vibrations
The magnet is to be protected against strong external vibrations, because the magnet might lose
magnetic force permanently and or the brittle ceramic magnet material might break.
*ferromagnetic: see chapter General/Ferromagnetism

Device description
User manual Neoflux® quick-cleaning magnetic filter 12
Cleaning
Minimum 2x per day cleaning (Fe disposal) of the device is advised or more / less when the magnet
bars catch very much / just a little Fe. Clean magnets provide an optimal magnetic filtering. Also it
prevents Fe accumulation on the magnet bar tubes and the problems that can be caused by that. So,
make sure you clean more than you think is necessary, to achieve a satisfactory result of the magnet
device.
For dirt cleaning, see chapter Maintenance
Deliverable specials
High product temperatures
For higher temperatures, up to 200 °C, there is the possibility of using other magnet material than the
standard Neoflux® magnets inside the magnet bars.
Abrasive products
If you have an abrasive product, we can supply the magnet bars and /or inside housing with a protective
coating, like for instance a tungsten carbide coating.
Use in FOOD product flows
The magnetic filter can be adapted so that it can be used satisfactory in your specific food flow. It’s
standard execution already is delivered in gap-free SS AISI316 or AISI316(L), but can be made in
combination with other – for instance prescribed or delivered by customer – food improved materials.
Surface treatments like electrolytic polishing, staining, etc. are naturally possible.
Additional measures are often necessary, when the filter is used in Food product flows
ATEX
The magnetic filter is ATEX II 3D compatible on the outside, for use in Ex dust zone 22. When
components are built-on or built-in which carry their own identification plate, then these components can
cause the overall device to be not suited for use in Ex dust zone 22. See Identification plate(s) and
spec’s for exact Ex codes.
It is however always users own responsibility to take the right precautions when using the magnetic filter
in Ex zone 22, like in-time cleaning to prevent for thick accumulating dust layers, and suitable grounding
measures.
Read this manual thoroughly for all ATEX measures.
When you want an ATEX certificate to come with the Magnet, then it is necessary to specifically
request so when the order is given. Extra price will be charged!

Device description
User manual Neoflux® quick-cleaning magnetic filter 13
Working principle
Drawing: Quick-cleaning of magnetic filter
•Goudsmit magnetic filters are able to remove ferromagnetic (Fe) particles of only 30 microns in
size from fluids and powders transported under pressure. The filters have a wide range of
applications like the foodstuffs, pharmacy, and ceramic industry, but the principle is always the
same. The powerful Neoflux® magnetic bars penetrate deep into the product so that they retain
even the smallest Fe particles. The bars can be removed from the product flow for cleaning by lifting
the lid.
•Sanitary magnetic filters are specially designed to meet the exacting demands of the foodstuffs
industry. They are polished extra smooth on the inside (also the weldings) and have no nooks and
crannies.
•Double walled industrial execution filters are specially geared to the removal of Fe particles from
products that tend to coagulate, such as chocolate. The industrial filters used for this purpose are
fitted with a double wall to allow a continuous flow of hot water so that the product stays liquid.
•In the product channel several Neoflux® magnet bars are placed.
•These magnet bars are tubes with a magnet package inside.
•The product always passes 1 magnet bar very close.
•The Fe containing material will be attracted by the magnets and will "cling" onto the extractor tubes,
while the filtered product flows further.
•The Fe will stay on the tubes until it will be removed manually. This can be done by taking out the
complete magnet unit (Fe out) and executing a cleaning action by pulling the magnet bar unit out of
the extractor unit (quick-cleaning).
•The magnet bar unit can be taken out manually, or by shoving over a side guiding, dependant of the
type and or size of the magnetic filter.

Construction
Drawing:magnetic filter, quick-cleaning extractor type
•The magnetic filter standard has flanges with bolt holes for easy mounting in your product channel.
Other couplings / joints can also be ordered.
•The magnetic filter has several magnet bars, placed in a way that the product flow, contaminated
with Fe parts, will always pass minimum 1 bar very closely, while flowing through the magnet filter.
•For cleaning the Fe from the magnet unit, the assembled unit of magnet bars + extractor tubes has
to be taken out the product channel. This can be done by loosening the fasteners that clamp the
extractor plate to the housing.
•The magnet bar unit has magnet bars with enclosing SS tubes, that are welded to an end plate with
a hand grip at the other side. The magnet bar unit can be pulled out of the extractor unit by
pulling the hand grip. In some cases the magnet unit has to be unlocked first to be able to shove it
out of the extractor unit!
Photo: magnetic filter with magnet lock
•The extractor tubes (with bottom plate) are also welded to a - holed - end plate. This extractor plate
is also the door that closes the housing opening dust-tight by tightening the fasteners and thereby
also clamping the sealing in the opening.

prevents Fe accumulation on the magnet bar tubes and the problems that can be caused by that. So,
make sure you clean more than you think is necessary, to achieve a satisfactory result of the magnet
device.
More cleaning: see chapter Maintenance
Pay attention to personal dangers / wear protective clothing, glasses, shoes, hand gloves !
Drawing: Cleaning of magnetic filter
Fe disposal working order:
1. Stop the product flow.
2. Loosen the fasteners.
3. Take out, or shove out over the side guides (depending on the version), the filter top (total magnet
bar unit) as far as possible by the hand grip.
4. Place the filter top far enough away from the housing on a clean, non-magnetic surface. With a
semi-automatic magnetic filter, the second stage will automatically take place pneumatically.
5. Clean the magnet bars manually with soft cloth and safety gloves. Clean extra with a soft cloth and or
a suitable SS cleaning fluid when necessary.
Extractor type:
•Shove the magnet bar unit out of the extractor tube unit (loosen the magnet locking device first
when present); For semi-automatic filters, the 2nd stage will automatically be pneumatically
actuated.
•catch the Fe parts that will now fall off the extractor tubes;
•place the magnet bar unit far enough away from the extractor tube unit on a clean surface.
•Sweep with a brush or soft cloth and or blow clean the extractor tubes (not in the direction of or
over the magnet bars or filter housing!) on in- and outside.
•Shove back the magnet bar unit into the extractor tube unit; make sure that no (new) dirt gets
trapped in-between the magnet bars and extractor tubes! (semi-automatic filters will actuate this
stage automatically).
•Lock by locking device if necessary and make sure that they stick together tight.
6. Place the filter top unit back into the device.
7. Tighten the closure.
8. (Re-)Start the product flow.
Take out magnets

Installation
User manual Neoflux® quick-cleaning magnetic filter 16
Installation
Transport and placing procedures
•Clear the area under the magnet during lifting and transport.
•Bolt the joints / flanges of the device tightly to the inlet and outlet joint / flange of your product
channel. Improper alignment and loose assembly may cause leakage of raw product.
•Ensure that the product channels are strong enough to support the weight of the magnetic filter and
raw product in it. Reinforce them when necessary.
The weight of the device is stated on the identification plate.
•Install the magnetic filter in a well reachable height for the operators when possible. A suitable height
eases the working, cleaning and Fe disposal process.
•Work safely; make sure there is enough working space, use proper scaffolding, lifting devices,
ladders and other help materials, so the device can be lifted, transported and installed without safety
risks.
Magnet bar protection
The magnetic filter has fragile extractor tubes and or fragile magnet bar tubes. The tubes have a small
wall thickness, which has the advantage of ensuring a high grade of Fe separation. Disadvantage is that
large, heavy Fe and/or other parts in the product flow can easily create bumps in the tubes.
Ensure that large, heavy parts are filtered out of your product flow before it passes the magnetic filter!
Advise: place a sieve (filter) in front of the magnetic filter!
See also chapter Maintenance
Damage to the magnet bar and or extractor tubes and/or damage caused by damaged tubes (when
used) is not covered by guarantee.
Gasket material / grounding
To prevent the build-up of static electricity, make sure there is metal bridge between the magnetic device
/ product channel and the installation. The completed installation must also be grounded.

Start-up
User manual Neoflux® quick-cleaning magnetic filter 17
Start-up
Before start-up, make sure that:
•The device or the installation has no damages or malfunctions.
•All connections (electrical, mechanical, pneumatic) have been made properly.
•The device or the installation is placed and situated correctly.
•All protective covers (if applicable) have been fitted correctly.
•That all objects larger than 10mm are blocked from entering the product channel.

Maintenance
User manual Neoflux® quick-cleaning magnetic filter 18
Maintenance
Magnetic systems attract Ferromagnetic particles. Regular cleaning is essential.
A clean magnet functions considerably better
All parts are best cleaned with pressurized air and/or a soft cloth. It’s also possible to deep clean with
special cleaning fluids that do not harm the material. Ensure that these fluids do not contaminate the
product
Regularly check that all warning pictograms and the identification plate are present at the correct locations
on the device. If warning pictograms or the identification plate should get lost or damaged, immediately
apply new ones to the original locations.
Always inform operating personnel regarding planned inspections, maintenance, repairs or if attending to
breakdowns.
Magnet bars
•As a following of the passing product (abrasive or not) and the Fe contamination the magnet bars /
extractor tubes can wear out sooner or later.
Wear as a following of abrasive product can be reduced by coating the outside bars, with for instance
tungsten carbide.
Please contact GOUDSMIT magnetic systems for advice.
•During maintenance and or cleaning one has to be careful with the magnet bars to prevent them from
getting damaged.
•Heavy parts (Fe or product), may hit the bar in a way that bumps occur. The bumps will possibly
block the movement of the magnet bars inside the SS tubes (extractor type) and so damage the
magnet material, or damage the magnet material underneath the SS protection bushes or tubes
(non-extractor type) .
When a magnet bar and or extractor tube is damaged it has to be replaced by another (spare)
one immediately to prevent further damage to the magnet bar and or cleanflow. The damaged
bar and or extractor tube can be sent to Goudsmit Magnetic Systems for repair/revision.
Replace magnet bars / extractor tubes
a. Send the complete magnet bar unit to Goudsmit Magnetic Systems
b. Dismount the damaged magnet bar by loosening the bolt in the end plate. Send the magnet bar to
Goudsmit Magnetic Systems.
Cleaning & ATEX
To prevent explosion risk, avoid dust clouds and the build-up of dust layers.
If dust particles or layers heat up they may ignite and burn. This in turn can ignite airborne dust clouds
and cause an explosion.
