ASC Series Belt Driven Rotary Screw Air Compressors
AIRKOM promises
suitable, trouble-free and high performance for
every kind of application with its ASC series
oil-injected rotary screw air compressors.
Manufacturing and assembly of every single part of
these compressors, in which latest engineering
software is used during design and analysis phases,
is realized considering international quality
standards.
EASE OF USE
ASC series compressors are manufactured to be
employed different areas of application without any
performance loss. High performance and quality grade
parts used in manufacturing and assembly of these
products which are designed to make users in every
level of experience easily adapt and learn, provide
long maintenance periods and thus, low operating
costs as a result.
WIDESPREAD AFTER-SALES SUPPORT SERVICE
As having operations in more than 100 countries
around the globe and possessing more than 150
authorized dealers in Turkey, AIRKOM offers reliable
use of the products to its customers with its
after-sales support network.
ROTARY SCREW BLOCK
• New generation rotary screw blocks, designed with
latest technological tools like “Computational Fluid
Dynamics (CFD)” and “Finite Element Method (FEM)”
and manufactured using high-end manufacturing
techniques, provide high efficiency, durability and
low energy consumption with new rotor profile and
lobe combination.
• Block contains new generation bearing system in
which the bearings with three times more load
carrying capacity than the standard designs are
employed.
• As new rotor profile permits less air leakage
occurrences with optimal lobe combination and
decreases the torque needed to operate, less energy
is needed to operate that leads to less operating
costs.
• Gearboxes are chosen with respect to AGMA
(American Gear Manufacturers Association) standards.
MAIN MOTOR AND DRIVE SYSTEM
• High efficiency IE2 class IP55 motors working with
380V/3 phase/50Hz power inlet are used as a standard
in ASC series.
• Driving the gearbox shaft is realized by
direct-drive mechanism with a flexible coupling
placed between rotary screw block and main motor
shaft.
• As the mechanical transmission losses are less,
the direct-drive mechanism is approximately three
percent more efficient than the belt-pulley
mechanism and it is mostly maintenance-free.
• In the absence of belt and pulley, noise and
vibration levels get noticeably lower.
AIR SUCTION SYSTEM
• It’s developed by using sophisticated engineering
analysis tools like FEM and “Fluid Dynamics”.
• With its simple design consisting of three control
block units, a solenoid valve and a control
cylinder, periodical maintenance services of the
suction regulators are easily and quickly realized.
• First class materials used in the suction
regulator manufacturing and lessened seal amounts
provide reliable operating performance up to 8000
hours.
• With the suction valve which gets fully
perpendicular position when it’s opened, almost
straight and unidirectional airflow, increased air
outlet area by %25 with the new profile design, the
suction regulator promises low pressure drops and
high performance.
• Double stage air suction filter system consisting
of replaceable front-panel filter from micro-glass
fiber, replaceable cassette type air intake filter
with paper element minimizes the problems caused in
dirty environments by providing clean air for the
rotary screw block and the cooling system.
AIR / OIL SEPARATORS
• More effective separation is realized at less
volume with the progressive type, deep bedded and
meshed separation layers.
• These separators have high performance design
providing three-stage separation.
• Less than 3 mg/m3 of oil density is transferred
with compressed air during separation.
COOLING SYSTEM
• Aluminum combi cooler with long-life Bar/Plate
system guarantees trouble-free operation at all
kinds of conditions.
• Four-way thermostatic valve lengthens the
lifecycle of oil and eliminates the risks of
malfunctioning by preventing condensation at low
temperatures.
• New blade profiles are supported with silent and
effective axial fans operated by a standalone
electric motor.
• New fan seats are employed to provide easy access
and short time periods for clean-up during
maintenance service.
SAFETY AND WARNING SYSTEMS
• Main motor and fan motor overload control
• Phase order, absence and instability control
• Main motor overheat monitoring with PTC.
• Rotary screw overheat control
• High pressure control
• Separator dirtiness warning system
• Intake filter dirtiness warning system
• Safety valve for separator tank
• High pressure safety valve
• Emergency stop button
• Maintenance time warning system
ELECTRICAL SYSTEM
• ASC series has LCD control panel indicating
operational and service functions in the way that
users from every level of experience can easily
understand.
• The mechanical safety systems are supported with
PLC controlled safety switches and relays to prevent
all possible risks that can occur during operation.
• While designing the electrical cubicle, the
products which are produced by globally accepted
brands are selected.
CANOPY DESIGN
• Canopy design requiring minimum working space
• Ergonomic design that provides easiness for
maintenance service by enabling access to every part
of the compressor.
• Easy demountable-mountable service covers.
• Vibration pads produced from special rubber
material to eliminate vibration and its
consequences.
• Electrostatic powder paint that is durable against
corrosion and impacts.
• Flameproof canopy overlay that minimizes noise.
STANDARD FEAUTURES
• High efficiency rotary screw block
• 380V/3 phase/50Hz IE2 efficiency class IP55 main
motor
