5. STORAGE AND TRANSPORT
The compressor is shipped from the factory in
transport packaging. This protects the
equipment from damage during transport.
The original compressor
packaging must be used for
transport whenever possible. The
compressor is shipped in a
vertical position and must be
secured using transport straps.
Protect the compressor from humid
and dirty environments and extreme
temperatures during transport and
storage. A compressor in its original
packaging can be stored in a warm,
dry and dust-free area. Do not store
near any chemical substances.
Keep packaging material if possible.
If not, please dispose of the
packaging material in an
environmentally friendly way and
recycle if possible. The
transportation carton can be
recycled with paper.
The compressor must be
transported only when all air has
been vented. Before moving or
transporting the compressor,
release all the air pressure from
the tank and hoses and drain the
condensed water.
Ambient conditions for storage and
transport
Products may only be stored and transported
in vehicles that are free of any traces of
volatile chemicals under the following
conditions:
Temperature: +0°C to +50°C,
Max. relative humidity: 90%,

7. PRODUCT DESCRIPTION
7.1. Model variations and theiruses
The compressor is used as a central source of
clean, oil-free compressed air to power
individual devices and equipment with
compressed air used in large dental clinics
and laboratories, in hospital wards and other
settings where the parameters and properties
of the compressed air are suitable to the
specific application.
Compressed air supplied by the
compressor is unsuitable for use with
artificial lung ventilation devices without
further filtration.
