Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the block from the air distribution network to ensure
that no compressed air can flow back into the block.
➤ De-pressurise all pressurised components and enclosures.
➤ Welding, heat treatment and mechanical changes are forbidden as they can effect the strength
of the material.
The safety of the machine is then no longer ensured.
Compressed air quality
The composition of the compressed air must be suitable for the actual application in order to pre‐
clude health and life-threatening dangers.
➤ Use appropriate systems for air treatment before using the compressed air from this block as
breathing air and/or for the processing of foodstuffs.
➤ Use lubricating oil compatible with foodstuffs if compressed air can come into contact with
them.
Quality of discharge air
The quality of the discharge air and any substances it may contain depends on the quality of the air
drawn from the vacuum network.
➤ Never breathe in exhaust air.
➤ Ensure that the discharge air is led to the outdoors through a point far from any persons.
Rotating components
Contact with rotating drive shafts or rotors can cause severe injury.
➤ Secure the blower block against unintended starting.
➤ Wear close-fitting clothes and a hair net if necessary.
➤ Fit covers and guards to prevent accidental contact.
Temperature
High temperatures are generated during compression. Touching hot components may cause inju‐
ries.
➤ Do not touch the hot blower block.
➤ Avoid contact with hot oil when changing the oil.
➤ Wear protective clothing.
Noise
The non-insulated blower block generates high noise emissions potentially resulting in hearing
damage.
➤ Operate the machine only with adequate sound damping.
➤ Wear hearing protection if necessary.
