The machine is intended for the suction and/or compression of air and other dry, non-aggressive,
non-toxic and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on the machine
and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is capable of maintaining ultimate pressure, see
The machine is suitable for continuous operation.

Standard Accessories
2.3.1
Vacuum Regulating Valve
The vacuum regulating valve (VRV) controls inlet pressure when the machine is used on vacuum du-
ties (optional for SV series and not available for SD series).
For SV 1025 C and SV 1040 D heavy duty operation where machine runs against a closed inlet for a
longer time (for example pick & place), we propose to configure the machine with EK 60 vanes to-
gether with the vacuum regulation valve (VRV), which should not be fully closed.
2.3.2
Pressure Regulating Valve
The pressure regulating valve (PRV) controls pressure when the machine is used on overpressure
duties (standard for SD series, not available for SV series).
2.4
Optional Accessories
2.4.1
Non-return Valve
A non-return valve, fitted to either the inlet or the discharge line, protects the system against ingress
of air or depressurization, should the machine stop for any reason. The installation of non-return
valves is recommended if the lines of more than 5 meters are used.
2.4.2
Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter
is available with a paper or polyester cartridge.
2.4.3
Hose Nipple
A hose nipple, depending on the version, could be fitted to the inlet and/or the discharge line. It al-
lows an easy connection to the machine with a flexible hose.
