4.3. Compressed air connection
It is recommended to use galvanized steel or plastic tubes for the
compressed air system.
When the compressed air treatment equipment (filters, dryer) is installed, the
existing compressed air piping should be replaced with a new one, unless
air supplied previously was treated by similar equipment.
Each BERG compressor should be connected to the compressed air network
by using a flexible conduit or flexible connector (axial expansion joint) and
shut-off valve.
4.4. Compressed air treatment
Depending on the required quality of compressed air, some compressed air treatment
equipment such as water separators, filters or dryer should be additionally installed
downstream the compressor.
Our specialists will select the appropriate equipment free of charge.
