Safety valve / non-return valve
The compressor is protected from exceeding the
permissible operating pressure by a safety valve.
The safety valve opens at 15 bar / 218 psi.
The compressor is protected against backpressure
from the compressed air network by means of a
check valve on the pressure side.
Protective covers and enclosure panels
The cooling air fans are covered with protective
mesh.
The coupling between the drive and the
compressor is protected by a mesh guard.
The housing of the compressor is designed so
that any broken parts that may be thrown off are
retained within the compressor.
The compressor housing serves as a sound
protection cover.

Hot surfaces
Some parts of the compressor become hot in
operation (up to 120 °C / 248 °F). A hazard
warning sign on the compressor enclosure warns
of this danger.
Before beginning maintenance and repair work,
the compressor must have cooled off sufficiently.
Personal protective equipment
We recommend wearing the following personal
protective equipment:
Safety shoes
Safety glasses whenever working with
