3.1 Application
The machine is intended for the suction of gases which contain a high percentage of wa-
ter vapour.
Other agents should not be transported. In case of doubt, please contact your Busch
representative.
3.2 Standard Accessories
3.2.1 Gas Ballast Valve
The gas ballast valve mixes the process gas with a limited quantity of ambient air to
counteract the condensation of vapour inside the machine.
The gas ballast of the Aqua version has a larger air volume flow than a standard R5.
The gas ballast valve has an influence on the ultimate pressure of the machine, see Tech-
nical Data [►8].
3.2.2 Thermostatic Valve
It allows to fix a higher operating temperature than a standard R5.
3.2.3 Temperature Switch "Oil"
The temperature switch monitors the oil temperature of the machine.
It has two switch points.
Depending on the oil type, the machine must be stopped when the oil reaches a certain
temperature, see Oil [►8].
3.3 Optional Accessories
3.3.1 Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas. The
inlet filter is available with a polyester cartridge.
3.3.2 Water Separator
It allows to retrieve a certain amount of condensate at the machine exhaust. It is
equipped with a drain plug at its bottom.

4 Installation
4.1 Connecting Lines / Pipes
• Remove all protective covers before installation.
• Make sure that the connection lines cause no stress on the machine‘s connection; if
necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the machine.
In case of very long connection lines it is advisable to use larger line sizes in order to
avoid a loss of efficiency. Seek advice from your Busch representative.
4.1.1 Suction Connection
Connection size(s):
– Ø60 mm hose for RA 0165-0305 D
– Ø90 mm hose for RA 0400-0630 C
– DN150 PN16, EN 1092-1 for RA 1000-1600 B
The inlet connection may be equipped with a ball valve.
Depending on the specific order, other connection dimensions may apply.
4.1.2 Discharge Connection
Connection size(s):
– G2 for RA 0165-0305 D
– G3 for RA 0400-0630 C
– 2x DN125 PN16, EN 1092-1 for RA 1000-1600 B
Depending on the specific order, other connection dimensions may apply.
