COMMENCING INSTALLATION.
Static electricity.
Ensure, that where required, the compressor and ancillaries are earthed
in accordance with BS5958 Part 1 1992; ‘Control of Undesirable Static
Electricity’.
Powder-air combinations are potentially explosive.
Drive line.
It is the responsibility of the installer of the equipment to ensure all rotating
and moving parts of the installation are adequately guarded to a standard
which complies with the prevailing safety legislation.
Compressor.
The compressor has internal moving parts some of which may be accessed
through the inlet and outlet apertures. Do not place any objects especially
fingers into these apertures since personal injury could result.
Installation.
A relief valve must be fitted in the outlet pipe work as close to the
compressor as possible. The valve must be positioned so as not to vent air
onto any personnel since the air discharged will be hot and can cause severe
burns.
Storage/Infrequent Usage
Before the machine is installed or when it will not be used for long periods:
• Store in a dry, heated building.
• Handle with care and keep the suction and delivery ports covered.
• Rotate the drive shaft each week, in the direction shown by the arrow on
the cover.
Where the compressor is mounted on a vehicle and located outside, it
should be operated for at least 15 minutes each week (twice a week In damp/
cool conditions)
Fire.
The compressor includes seals made of fluoroelastomer polymers which
degrade if exposed to temperatures above 300°C. If the material has been so
exposed then it must not be handled with bare hands.
Surface temperatures can exceed 150°C. Highly combustable materials must
not come into contact with the discharge pipework or compressor body.
Relief Valve Check
This procedure should be carried out every month to clear the valve seat and
check the valve is functional. (Ear protection is recommended)
Noise
Gardner Denver Drum Ltd’s own tests show maximum noise levels for the
installed SC200 running at 1800 rpm should typically not exceed 92 dB(A) at
1 metre.
Belt Drives
The SC200 compressor should not be belt driven.

General
2.1 Product General Description
The SC200 is a lightweight, compact, oil free, contactless, low maintenance
screw compressor designed for the contaminant free discharge of bulk
liquids from general purpose tankers. Typical applications include:
1. Liquid foodstuffs.
2. Solvents.
3. Acids.
4. Alkalis.
5. Hot Bitumen.
6. Resins and other chemicals.
The SC200 comprises of two synchronised screw rotors, a combined main
body/step up gearcase assembly and a bearing carrier.
Screw compressors operate on the displacement principle and belong to the
group of multiple-shaft displacement machines.
Two parallel non-contacting screw rotors are mounted inside the casing.
As the machine rotates, the meshing action of the two helical rotors creates
cavities within the machine. During the Inlet stage these cavities increase
continuously drawing air into the compressor. When the cavity reaches it’s
maximum size the compression process begins.
The air is compressed as the cavity reduces along the longitudinal axis and
eventually discharged through the air delivery flange and discharge silencer,
when fitted, into the connecting pipework.
The compact shape and size of the compressor make it ideal for mounting
inside the chassis on most vehicles to enable low cost prop. shaft driving.
A through shaft allows CW or ACW input drive rotation with mounting points
on either side of the machine to provide further flexibility.
The standard compressor package consists of the following equipment:
• Basic SC200 machine and mounting kit.
• Inlet filter/kit.
• Relief valve.
• Check valve and flange pack.
• A discharge silencer is available as an optional extra.
• Couplings can be supplied as an optional extra.
2.2 Drive Options
The SC200 can be driven using the following drive systems.
Prop. Shaft drive Direct from a vehicle PTO.
Hydraulic drive Several drives available depending on application.
Electric motor Packages on base frames.
Engine drive Packages on base frames.
The shape and size of
the compressor make it
particularly suitable for PTO/
prop. Shaft driving inside
the vehicle chassis on most
applications.

Installation
3.5.3 Pressure relief Valve
• The relief valve is installed to prevent the SC200 from encountering
pressures beyond it’s operating range.
• The relief valve should be installed as close as possible to the discharge port
of the machine either in the reactive silencer (see page 25) or prior to any other
discharge ancillary (See page 24).
• The relief valve is preset, wired and leaded (tamper proof) and fitted
to protect the SC200 (rather than the system which should be protected
by the vehicle tank relief valve) against pressures of over 2.5 barg.
Adjustment of the machine relief valve will invalidate the warranty of the
SC200 and the relief valve.
The relief valve required to protect the machine is a custom component set
to gardner Denver specifications. This valve is only available from Gardner
Denver and use of any other valve may invalidate warranty.
When mounting the pressure relief valve observe the following:
• Mount the valve as shown on pages 24 and 25.
• Make sure that the component markings and the safety seal are present.
• The valve must not be blocked.
• Do not use the pressure relief valve to regulate the compressed air
delivery.
3.5.4 Noise Control
Discharge Silencer (Reactive)

3.7 Drive
• The rotor shaft should not be exposed to the axial thrust of the drive.
• Do not fit drive components onto the rotorshaft with a hammer.
• If the compressor is powered by a combustion engine, the engine must
have speed control which ensures that the compressor cannot run at
higher than the permitted maximum speed if the load drops.
• Install a coupling guard complying with safety instructions.
• Please note the step-up or step-down ratio of the transmission (truck p.t.o.,
large gear assembly, small gear assembly, etc.).
• It is recommended that speed control at the machine is provided with
indication at the place of operation.
• Check the speed after setting up the compressor and fix up a notice for
the truck driver.
3.7.1 Drive by Hydraulic Motor
• The compressor side half coupling is supplied loose.
• Suitable coupling flanges can be supplied on request.
3.7.2 PTO and Prop. Shaft Drive Alignment
Shaft Cover
• The compressor can be driven from either end of the input shaft
(see section 3.3 for possible mounting arrangements).
• The clockwise end of the compressor input shaft is protected with a
shaft cover. If this shaft is required, remove the cover and refit it over
the unused shaft at the opposite end of the machine.
Drive couplings
• Before fitting the drive coupling, ensure the machine shaft and drive
coupling are clean and damage free to help ensure the flange fits correctly.
• Both the shaft and the coupling bore should be smeared with a light oil to
aid future separation.
• A Hollow Set Screw (Grub Screw) should be used for retaining the drive
flange in position on the shaft.
• Apply Loctite 270 to the Grub Screw and tighten to a torque of 7Nm.
• Flange/coupling removal should only be undertaken with the aid of a
puller type device with a screw in the shaft end (see Fig. 5a) to avoid
damaging the flange or shaft end.

5.5 Inlet Air Filter
The maintenance indicator indicates the state of the filter element in the
Inlet air filter. The filter element should be replaced/cleaned when the
Maintenance indicator enters the red portion of the blockage scale (Fig. 7a/1)
If the indicator valve has entered the red portion of the scale:
• Press the reset button and re-check with the compressor operating.
• If the blockage indicator still returns to red, the filter must be either
cleaned or replaced.
Cleaning the Casing
• Unclip the clamp retaining the end cover (Fig. 7b/1) of the air filter and
remove it noting the position of the vacuator valve (Fig. 7b/5).
• Empty out any dust or dirt and then re-fit in the original position (vacuator
valve downwards).
Cleaning/Replacing the Element
• Remove the end cover by releasing the retaining clips and withdraw
the filter (Fig. 7b/1).
• Clean the filter by blowing compressed air through the filter from the
inside outwards or replace with a new filter element (Fig. 7b/2).
• Clean the inside of the filter body and end cover by blowing with
compressed air.
• Replacement of the element/end cover is a direct reversal of the above.
• After cleaning the filter, push the hook-shaped pressure switch of the
maintenance indicator inward (the colour changes from red to colourless)
• The maintenance indicator is again ready for service (Fig. 7a/2).
Make a weekly check of
the vacuator valve by
compressing the valve to
note any dust collection.
NOTE
Stop the machine before
cleaning or replacing the
filter elements
