Any amendments should be attached to the original manual. Machine identification and serial number
can be found on the identification plate fixed to the machine body.

1.1 Safety recommendations


Users of Guyson equipment are advised to make sure they have identified any hazards associated
with their specific air washing processes, including:

Use of compressed air


Fire/explosion risks
Suitable procedures for dealing with fire hazards
Production of carcinogenic or toxic substances from component surface removal
Any other known hazards

Users are responsible for ensuring that they have implemented any current regulatory requirements,
e.g. COSHH, to deal with any potential risks and/or hazards associated with their processes.

ATEX ZONE DESIGNATION

The ATEX Directives 2014/34/EU (product requirements) and 99/92/EC (user requirements) are
implemented by the Equipment and Protective Systems intended for use in potentially explosive
Atmospheres Regulations 1996 (EPS and the Dangerous Substances and Explosive Atmosphere
Regulations 2002 (DSEAR) respectively.

We are able to provide equipment that is suitable for use in a hazardous area, and/or equipment that
is suitable for use when a hazardous area is created within a system, but it is the end users’
responsibility to classify the area in which the equipment is to be used and/or the explosivity of any
internal atmosphere created within the system. This is defined in Section 2, Article 3 to 9 of the
99/92/EC Directive (ATEX 137).

Unless we have been advised otherwise, we have to assume that the equipment will be used in an
area that is not classified as potentially explosive, and uses a process which will not create an
explosive atmosphere within the equipment.

3. Installation
The system comprises of the following unit:

• Formula Cabinet

• Dust Collector

Remove packing materials and check inside cabinet for loose items.

3.1 Location
The equipment must be located on a clean, dry surface.

The Formula 1400 and 1600 Cabinets are designed to stand on the floor, the Formula 1200 Cabinet
is designed to stand on a workbench approximately 700 mm high. Locate the cabinet in the required
position and orientation; always allow sufficient room around the units to fully open doors/lids and to
give access for operation and maintenance.

Care should be taken to ensure all parts of the system are level

3.2 Assembly
Connect the cabinet outlet on the blast cabinet to the dust collector inlet:

Connect the flexible extraction hose from the cabinet outlet to the dust collector
inlet using the sealing bands and hose clamps supplied.

Maintenance
Manual

3.2.1 Compressed air connections


The air supply should be from a manual shut-off valve that will exhaust down-stream air and be clean,
dry and oil-free.

The machine requires a compressed air supply at a maximum of 6.0 bar (90 psi) at the filter inlet. This
should be supplied through pipework with a minimum bore of 10mm with no restrictive air fittings. The
filter inlet has a ¼” BSP fitting, as shown below.

Connect the main compressed air supply to the pneumatic isolator valve

Take care that any jointing material (e.g. PTFE tape) does not enter the pipework.

3.2.2 Electrical connections


Electrical installations should only be carried out by qualified electricians

Please see “Electrical Installation of Dust Collectors and Cyclones” in the appendix

A power supply should be


taken to the starter box situated
on the side of the dust
collector.

The electrical supply to the lighting on


F1200, F1400 and F1600 cabinets is via an
IEC lead.

PLEASE NOTE: It will be necessary to fit a bulb to the Bulkhead Light Fitting supplied
for Cabinet Illumination. Please note the maximum recommended power per lamp
bulb is 60 watts.

4. Testing installation
4.1 Testing installation procedure
After completing all the connections the cabinet operation should be checked.

Do not open the air supply at this stage.

• Switch on main electrical power supply

• Switch on cabinet light

• Start the dust collector:

o The direction of the impellor motor


should be checked visually against
the arrow on the motor. If rotation is in
the wrong direction on the single
phase motor, then Guyson
International should be contacted for
more information.

NOTE: Air will flow from the outlet


even if the fan rotation is wrong, but
only at a low level, so rotation must be
checked visually.

On a F21/F41 dust collector the motor is inside. Unclip the catches and remove the
front panel to check its rotation.

The best way to do this task is by starting then stopping the dust collector and watch
the fan as it slows down.

• Turn on the air supply by opening the main air valve

• Set pressure regulator to required air wash pressure

• Check all in-line connections for leaks and possible blockages

• Insert both arms through the armhole entries

• Depress the foot pedal (or trigger valve for Formula 1200)

• Check for a steady air blast from the gun and for possible leaks

• Remove arms from gauntlets, isolate cabinet from compressed air supply and ensure all
compressed air is discharged from the system, open cabinet and add blast media.

4.2 Media levels


The media should be added to the cabinet hopper; ¼ - ¾ of a 25kg bag of media should suffice.

4.2.1 Adding media to hopper


• Turn off the dust collector

• Open the cabinet door

• Pour media into the hopper

• Close the door

• Turn the dust collector on

5. Machine settings
5.1 Blast settings
The blast settings should be set in the order they appear in the following sections.

5.1.1 Blasting pressure


Air pressure controls the speed at which the blast media leaves the nozzle. Blasting speed increases
at higher pressures and shortens operation time. Never use a higher blast pressure than necessary to
achieve the finish required, this will normally be less than 80p.s.i (6 bar).

• Higher pressure air is less economical

• It may distort or damage components

• Greater media breakdown means higher media consumption

• Noise increases

Adjust the blast gun pressure


using the control knob on the main
air inlet filter. The gauge shows the
set pressure.

Operation &
Maintenance
Manual

5.1.2 Media pick-up tube


The setting of the pick-up tube in the media box has a significant effect on the blasting performance.
Adjustment varies with the media density, with denser media requiring more air to circulate them.

The greater the flow of media from the mixer box to the blast gun, the higher the rate of wear on
media hose, blast nozzle.

• Check that there is a supply of free-flowing, dry media to the mixer box

• With compressed air flowing through the blast gun gradually move the pick-up tube into the
mixer box with the chamfer facing upwards while a colleague watches the media flow from the
nozzle.

The pick-up tube is in the right position when you are just able to see the media stream
leaving the nozzle. If the media stream is intermittent then the pick-up tube has been pushed
too far in.

o Moving the pick-up tube out decreases media flow

o Moving the pick-up tube in increases media flow

• Lock the pick-up tube in place with the retaining screw

• Further adjustment should not be needed whilst using the same media

Retaining screw

Pick-up tube

O-ring is used to mark position of


the pickup tube in the mixer box.
This allows the tube to be
reinserted at the same position.

Operation &
Maintenance
Manual

5.1.3 Stand-off distance


This is the distance of the gun nozzle from the component. The stand-off distance should not normally
be reduced below 50 mm as media from the nozzle will be deflected or slowed down by media
ricocheting from the surface being blasted.

The impact of the media can be affected by the stand-off distance and the air pressure. The type of
media will influence this but a larger blast area may be achieved by increasing both the stand-off
distance and the blast air pressure.

5.1.4 Angle of blasting


The optimum angle for blasting for surface finishing is between 90 and 60 degrees to the horizontal.
Shallower angles can cause surface damage or compromise material properties. Greater angles than
this can be used for deposit removal where the surface finish is not critical and with softer media.

Blast guns should be angled to minimise interference between the outputs from different guns. This
will avoid disrupting the speed and direction of media between nozzle and component.

Always position guns pointing away from any cabinet openings; this minimises the risk of media being
blasted out of the cabinet.

Date: 03/2019 Page: 12
Operation &
Maintenance
Manual

5.2 Extraction settings


5.2.1 Dust collector
The air-flow must be sufficient to create a slight negative pressure inside the cabinet to prevent dust
from blowing out. The airspeed must also be high enough to carry the dust out of the cabinet and up
the extraction hose to the inlet of the dust collector. This varies with the size and weight of blast
media.

The suction in the dust collector should be such that a minimum amount of media is transferred into
the dust collection system.

This is altered with the damper on the dust collector


outlet:

• Opening the damper increases the suction

• Closing the damper reduces the suction

When setting the dampers/blast gates always keep the extraction air-flow to the minimum needed to
avoid pressurisation of the cabinet during blasting. Over time the filters in the dust collector will
become clogged with dust, and an increased air-flow may be necessary between filter changes and
maintenance. In systems with a cyclone the extraction should be set so that a minimum amount of
media is transferred into the dust collection system.

Always check the waste bin for good media when adjusting any settings.

Never try to extract reusable media for reuse in the machine.

7.1.4 Filter cleaning

THE MOTOR SHOULD BE SWITCHED OFF WHEN USING THE CLEANING


MECHANISM ON THE F21 DUST COLLECTOR

Filter cleaning must be carried out on a regular basis.


Initially this should be carried out every four hours, until
a working pattern is reached. On an F21/F41 dust
collector the filter cleaning system is manual. Pull and
push the knob back and forth to shake the filter clean.

After approximately five hundred hours use the dust will


have worked its way into the body of the filter and
cleaning with the cleaning mechanism will no longer
clean sufficiently to allow enough air through. This will
be evident by poor visibility in the cabinet and/or failure
to extract the dust even with the dust collector damper
fully open. A filter change will be necessary at this point.

7.1.4.1 Replacing the filter sleeves on an F21/F41 dust collector

ENSURE THE FILTER IS CORRECTLY POSITIONED SO THAT DUST


CANNOT BYPASS IT TO THE EXHAUST

ALSO ENSURE THAT THE MOTOR IS NOT RUNNING

Shake filters and allow


dust to settle

Remove front panel by


unhooking latches

Remove large worm-drive


clip from base of each filter
sleeve

Unhook top of each filter


from retainer clip

Carefully remove filter


from dust collector.

Replace with new filter


sleeve (Y1CA0000) by
hooking top of filter onto
retainer clip first then pass
worm drive clip over the
base of the sleeve and
secure to base of dust
collector. Re-fit front
cover.

7.1.5 Compressed air filter


If the dust and light debris is dry and not clumping together then the compressed air filter is working
correctly. If the dust and light debris is clumping together then there is a problem with the compressed
air filter or your air supply. Guyson International should be contacted for more information.

7.1.6 Hoses

Check the media supply hoses


(R6TB0018 for F1400 and F1600,
R6TB0014 for F1200) for signs of wear
and damage. Internal wear can be
determined by feeling the rigidity of the
tubing along its length. Any internal wear
will result in the hose feeling soft where
the hose wall is thinner. The first section
to go is usually next to the pickup tube.

Check the extraction hoses for holes or


breaks as these will affect the rate of
extraction from the cabinet.

7.1.7.3 Blast nozzle

Inspect the blast nozzle for wear. When the bore size has increased by 20% (6mm bore
@ 20% = 7.2mm) then the nozzle needs to be replaced. The effective bore of a nozzle
can be quickly checked by use of a twist drill bit.

The nozzle should be withdrawn from the gun body after 8 hours blasting and rotated by
5° to avoid uneven wear.

The picture below shows an extremely worn nozzle. Your nozzle should reach this
state as it will decrease its blasting effectiveness and may also damage the blast
gun.

If the door gasket strips are worn then:

• this allows noise to escape the cabinet more


easily

• media may be able to exit the cabinet

Item Code Description


R5SL0024 16mm wide x 5m roll
R5SL0027 25mm wide x 5m roll

7.1.9 Topping up media


Top up the media levels as required as media is consumed. This can be roughly gauged from the
waste bin on the dust collector. Regular additions of small quantities of media maintain an even
particle size and assist in producing consistent results.

10. Appendices
10.1 Electrical installation of dust collectors and cyclones
Guyson dust collectors and motorised cyclones (whether for single or three phase supplies), when
supplied to complement blast cabinets, are fitted with starters. These should be wired from the
customer’s switched fused isolator. The starter needs to be wired up by a suitably qualified electrician;
electrical schematics for the single and three phase systems are attached.

The supply required can be discovered from reading this chart:

Model Phase Voltage Cycle Power Full load


(Hz) (kW) current (A)*
21/41 1 230 50 0.37 3
41 3 400 50 0.37 1.4

* Fuses should be sized to comply with full load current. When sizing fuses, smallest fuse rating
should be used to suit motor and starting characteristics.

Single phase supply

Manual

Three phase supply

On both single and three phase motors it


is essential to check that the direction of
rotation matches the arrow attached to
the motor housing. This is best done
visually. If the motor is rotating in the
wrong direction, it will be necessary to
switch off the machine, isolate the
electric supply and reverse the position
of L1 and L2 on single phase machines
or any TWO of the feed wires (L1, L2 or
L3) on three phase machines.

If a problem occurs with installation then Guyson International should be contacted to provide support

If the yellow indicator is visible


where the arrow points to, the
blue reset button needs to be
pressed. If the Dust Collector is
still not functional, readjust the
trip setting up slightly.
If the problem persists, contact
Guyson International.
