This manual applies to the Kongskilde MultiAir 4000
blowers and FC4000 blowers.
The target group for this manual are operators, (electri-
cal) installers as well as maintenance and service staff.
Description:
The Kongskilde Multiair blower is designed for use with
pneumatic conveying systems, but is also suitable for
other industrial pneumatic solutions.
The blowers are equipped with a closed noise reduc-
tion cabinet, which ensures low noise levels.
The MultiAir FC models are equipped with a frequency
converter, which allows energy efficient adjustment of
the blower operating point, and simple control from the
supplied operator panel. The panel can be moved from
the blower to another location if desired.
The blowers are available in versions for clean air (P
blowers) and for material (M blowers).
Material may ONLY be transported through the MultiAir
blowers intended for material transport.
The scope of these blowers can be:
•
industries for the processing of plastics, for the
transport of granules and shredded plastics
•
bookbinding and printing, for transporting paper
trim
•
sawmills and joineries, for transporting sawdust
and chips
•
textile industry, for the transport of yarn waste and
fibers
•
tanneries, for transporting leather clippings and
shavings
Do not transport corrosive, abrasive or adhesive gases
through the MultiAir blower. The P blowers intake air
may well contain limited amounts of dust and particles,
e.g. from the return air from a separator.
The blower does not meet the requirements of the
ATEX directive, and no air may be transported through
the blower, containing dust and / or gases, that would
otherwise require ATEX zone equipment.
The blower
must therefore not be used to air with dust concen-
trations that may constitute an explosion hazard.
Intake air temperature must be max. 70 °C.
If attenuation of the intake noise is required, Kongskilde
offers a silencer, see section "Accessories".
Warning notes:
Make sure all guards are in place and properly secured
during operation.
Always disconnect power to the blower prior to repair
and maintenance. The main switch must be switched
off and locked to ensure the blower cannot be started
by mistake.
Never put your hand, head or other body parts into the
blower's intake or outlet while the blower is running, it is
life threatening to come into contact with the rotor of the
blower while it is in motion.
The blower should be installed in an accessible location
for maintenance and repair.
The working area around the blower should be clear
and trip free.
Make sure to have adequate lighting when working on
the blower.
The blower doors are heavy - make sure their gas
dampers and locking device are inspected regularly - if
one door falls down or pops up unintentionally, there is
danger of personal injury.
Be careful not to get your fingers or hands pinched
when the doors are opening or closing. Also watch out
for head injuries, when the doors are closed, there may
be sharp edges on the doors.
To prevent accidental contact with the impeller, the pip-
ing for exhaust air, and possibly supply air, MUST be
mounted with bolt couplings for which tools are required
for separation. Hence, tools MUST be used for separat-
ing all piping between the blower and the connected
machines!
In case there is no pipe connection on the inlet, a suc-
tion net must be installed!
The reason for this is, that according to EU-directive
2006/42/EC (Machinery Directive), it is not allowed for
any unauthorized personnel to gain access to rotating
parts. In case quick clamps are used, unauthorized
personnel could dismantle the pipes, and gain access
to rotating parts, or get sucked onto the b.
The blower speed is fully adjustable and controlled
from the operator panel (on FC models). In order not
to overload the rotor and motor, the blower speed can
not be set higher than what the blower is designed for.
Changing the electrical equipment in order to increase
the maximum blower speed is not allowed.
Use eye protection when working close to the air outlet
of the blower. In case of small particles in the conveyed
material, these might be blown from the air outlet of the
blower, causing eye damage.
The blower can move large volumes of air, and can
thereby generate high noise levels. If working around
the blower with open doors during operation, hearing
protection must be worn. Likewise, it must be ensured
that the connected piping is noise insulated, see sec-
tion "Installation".
If any abnormal vibrations or noise are observed, the
blower must be stopped immediately, and qualified as
-
sistance must be called.
