3.6 Ancillary Equipment
3.6.1 Relief Valve.
The D9000 unit must never be operated without the integral relief valve.
The relief valve must be capable of venting the full flow of the compressor, at a maximum
pressure of 2 bar g.(Please contact your Drum supplier for more information). The relief valve
must be mounted to vent away from the operator and a warning label must be attached near
to the relief valve, warning of the danger of burns by hot air venting.
The relief valve must vent direct to atmosphere.

A pleated aluminium or paper type inlet air filter is fitted to the D9000 unit to prevent the
ingress of any material that could damage the machine
(Refer to page 13 for replacement details).
3.6.3 Check Valve.
A check valve is fitted into the outlet silencer discharge port to prevent reverse rotation of the
unit which can be caused by pressurised air in the vehicle’s tank.
