3.1 Operative Range
The IMPACTS blast-cleaning machine S320RD is a downward blasting machine with a closed
abrasive circuit designed for the pre-treatment of horizontal surfaces. The bouncing impact of
metallic abrasive onto the surface thoroughly removes surface contaminants, coats of paint,
sealants, and thin coatings.
A suitable filter unit is integrated into the machine in order to separate the dust from the abrasive.
A specially designed dust collection system ensures dust-free operation of the machine and clean
air at the workspace.

The blast wheel method is a revolutionary invention based on a simple principle:
After mechanical pre-acceleration, the abrasive is thrown onto the surface at high speed by the
blast wheel. Once the abrasive has impacted the surface it rebounds into a rebound plenum. The
rebound plenum deflects the abrasive into an air current separator. In this location, dust and other
contaminants are removed from the abrasive so that only abrasive containing a very small amount
of dust is falling back into the abrasive storage hopper to reflow to the blast wheel.
The integrated filter unit provides a dust free working environment, and improved service life
of machine and tools. Ensuring a clean environment is a matter of ethics and should be observed
by professional associates. IMPACTS uses a particularly arranged filtering material that is certified
and has high filtration efficiency.

3.5 The Wheel Kit
The heart of every blast-machine is
the blast wheel (1) this will throw the
abrasive to the surface to treat, using
centrifugal forces. The blast wheel is
placed in a side force wheel housing
(2) protected with replaceable wear
plates (3).
The blast wheel is driven by a belt
drive and mounted on a bearing
unit (4). The correct rotation of the
S320RD blast wheel is CCW. (L)
The center of the blast wheel shows
a pre-accelerator, called impellor, (5)
feeding dosed quantities of abrasive
onto the blades of the turning blast wheel. On top of this is the control cage (2) which, once it is
carefully set, regulates the direction of the abrasive flow.
The Control Cage, held by two clamps needs to be adjusted (V) so the blast pattern shows to the
center of the machine. Turning the control cage CCW will move the Blast Pattern to the right and
turning it CW will move the blast pattern to the left.

8 Lever
9 Control lever magnetic-valve
The separator (1) is mounted to the end of the
rebound plenum. The deflector (2) and baffle plate
(4a) will stop the reflected abrasive.
The filter, connected to the hose connector (1b) will
generate an appropriate airflow within the separator
so this device will separate dust from abrasive. The
abrasive drops back to the storage where it has to
pass a wire mesh tray (3).

Operating Manual S320RD
15
This tray (3) is fitted to prevent any coarse contaminants from getting into the blast wheel. In order
to clean the wire mesh tray it can be removed from the side.
To regulate the flow of abrasive to the blast-wheel there is a magnetic-valve (5) fitted between
Storage-Hopper (1a) and feed spout (6).
This valve has a turnable shutter (5a) that is linked to a lever (8) controlled by the control cable (7).
Changing the angle of the shutter position results in a different amount of abrasive flowing to the
blast wheel. Feeding more abrasive causes more work and results in a higher load on the engine.
Load on the engine is indicated by the revolution counter.
Do not load more abrasive than recommended for the S320RD. The engine speed should be
between 3,250 and 3,300 min-1.
3.7 The Traction Drive
1 Hydraulic Drive Motor
2 Drive Wheel
3 Bypass Valve
The machine S320RD is driven by two hydraulic drive
motors (1). The drive wheels (2) are permanently
connected to the hydraulic drive motors.
To move the machine by hand, change the position of
the bypass valve (3). Once the machine is in place, be
sure to change back the position of the bypass-valve to
avoid inadvertent movements of the machine.
3.8 The Base Seals
1 Magnetic Seal
2 Brush Seal
3 Tail Seal
4 Adjuster Screw
5 Magnet Holder
6 Seal Plate
On the front and side are magnetic seals (1)
surrounded by brush seals (2). On the rear
you will find a seal called tail-seal (3). This
seal slides over the surface and prevents
abrasive getting out of the blast area.
All seals should seal against abrasive spray. The correct setting of the magnets is approx. 12mm
over the floor depending on the application. This setting is very important for best function of the
machine. The adjustment is done by setting screws. See chapter 5 for adjustment instructions.

S320RD Operating Manual

3.9 The Filter Housing
The filter housing (1) contains the filter
cartridges (2) as well as the automatic
cleaning system (10).
The cartridges separate the dust from the
air reducing the air becoming dirty.
For cleaning, there is an automatic
cleaning system which is supplied with
compressed air by a compressor.
3.10 The Dust Bin and Lifting System
Below the filter housing, the dust bin (3)
collects the dust. The dust bin collects
about 100 liters of dust and is supplied
with two wheels and one caster for easy
transport.
The dust bin (3) is fixed to the filter housing
(1) by a lifting system (5) which can be
operated by a movable lever (4).
For changing the position of the dust bin
handle (7,) loose the locking levers (6)
,move the handles to the desired position
,and retighten the locking levers.
3.11 The Fan
The fan unit (8) which is directly connected
to the filter housing, generates the required
vacuum.
To adjust the airflow, use the lever (9) which
controls the throttle valve in the top of the
air exhaust duct.

Operating Manual S320RD
17
3.12 The Automatic Cleaning System
The filter unit is equipped with an automatic cleaning system which cleans the cartridges during
operation of the filter unit. Traditional systems do not allow this. This system mainly consists of 3
components: the compressor, the air splitter, and the electronic timing control. The pressure gauge
and the differential pressure gauge integrated in the filter housing inform about the status of the
cleaning system.
3.13 Abrasive Media
In order to operate IMPACTS blast-machine S320RD
you need hardened, spherical abrasive. The machine
S320RD has been especially designed to be operated
with IMPACTS abrasive.
The IMPACTS abrasive is of very high quality and
owns the rebounding ability required for the efficient
use of model S320RD. The selection of the abrasive
is very important since this is the material to carry out
the surface treatment.
Take off the lid (2) from the separator (1), assure the
wire mesh tray (4) is in place, and fill up abrasive
(3) distributing evenly up to the bottom of the mesh.
Occasionally check function of the deflector shutter.
3.14 Selecting Abrasive Media
Media IMPACTOR S 290
