GENERAL DESCRIPTION
The D9000 compressor is an oil free hook and claw type compressor housed in an acous-
tic enclosure incorporating ancillary equipment. The unit is designed for the discharge of a
wide range of bulk powders and granules.(A D9000 fitted with an after-cooler is available
for the discharge of more heat sensitive products).
The D9000 is supplied in either Left Hand or Right Hand configuration to suit space
availability on the vehicle to which the unit is to be fitted (refer to Fig 3A).
A Belt Drive can be fitted to allow the D9000 to be driven from a PTO (Power Take Off)
rotating in either direction. On applications where drive from a PTO is not available, Drum
can supply hydraulic and electric drives or a remote diesel engine (for trailer or static
applications) Consult your Drum agent for appropriate drives.
Fig 1 shows a typical D9000 system package which features as standard:
• GRP acoustic enclosure and mounting bracket.
• Integral inlet filter.
• Integral Inlet and Outlet silencers.
• Relief Valve mounted on the Outlet Silencer.
• Check (Non Return) Valve mounted to the outlet port.
• Flange Pack and Air Inlet Pipe Kit.

(Refer Note)
Note: The free end of the Intake Air Pipe (89mm bore x 1 metre long) must be located in a
position where it will be free from the ingress of water and other contaminants and the
air supply is cool and dry. An alternative method is to connect the pipe to the vehicle air
inlet stack with minimum of 100mm bore or fit a suitable rain hood. It is the responsibility
of the installer to ensure that this meets the approval of the vehicle manufacturer.
