Compressors for universal use –
The solution for maximum reliability
Common features
• 2 power units, each with 2cylinders, twostage
compression
• Two power units fitted to one vessel –
maximum reliability (if one power unit should
fail) and sufficient reserves in the event of a
peak in demand
• With basic load alternation switch as standard
(control system for distributing basic
and additional air supplies for several power
units)
• Vessel with burned-in interior coating
• 15-year rust guarantee on all vessels
• Standard features include: all fittings, such
as electromagnetic valve or pressure switch
with relief valve for fully automatic operation,

Compressors for universal use –
The inexpensive solution with additional air requirements
Common features
• V-belt driven 2-cylinder unit with 2-stage
compression for 10 bar increases the output
and guarantees high efficiency
• Above 7.5 kW V-belt driven 4-cylinder unit
• Vessel with burned-in interior coating
• 15-year rust guarantee on all vessels
• Standard features include: all fittings, such
as electromagnetic valve or pressure switch
with relief valve for fully automatic operation,
motor protection, safety valve, pressure
gauge, check valve, condensate drain cock
and ball valve
• Standard features include: rubber vibration
elements
• Electrical connection 400 V/50 Hz (threephase
current)
• For compressors with a4kWmotor,
observe the regulations stipulated by the
local power station

• Itiscompulsory for all compressors and
power units above 5.5 kW to be started via
an automatic star-delta switch. This switch
is not included in the scope of delivery but
the start-up relief is
• Intermediate cooler and aftercooler quickly
cool the generated compressed air
• Equipped with all fittings and control vessels
for autonomous operation
• A pressure vessel with the appropriate
dimensions must be available to ensure that
the auxiliary compressor functions correctly.
The auxiliary compressor is connected to
this pressure vessel via an elastic connecting
pipe
• Can be used if the existing air flow rate is
insufficient, to cover peak capacities, to
guarantee 100% reliability and/or if old
machines require expensive repairs
