COMPACT Series
Easy to install, COMPACT blowers from KAESER are not
only designed with minimal operating and maintenance
costs in mind, but also to provide maximum reliability.
Furthermore, blowers equipped with an integrated controller and star-delta starter, or frequency converter (for flexible speed control), significantly reduce the amount of work
required for planning, installation, certification, documentation and commissioning.
Integrated engineering
COMPACT rotary lobe blower packages are delivered
complete with sound enclosure and an optionally integrated frequency converter, or star-delta starter, as power
switching equipment. All electrical equipment is dimensioned according to required performance data and is
wired and programmed for EMC compatibility in accordance with applicable
regulations.

Using various sensors, the optional internal SIGMA
CONTROL 2 blower controller monitors and controls all
relevant parameters to provide reliable and efficient operation at all times. Available remote monitoring and control
further contributes to optimised blower availability.
A variety of communications modules ensures seamless
connectivity of SIGMA CONTROL 2-equipped blower
systems to master controllers such as the SIGMA AIR
MANAGER 4.0 and/or other centralised control systems.
Durability and efficiency
As with all KAESER products, COMPACT series blowers
are designed and constructed to deliver maximum efficiency, reliability and durability. Together with their minimal
maintenance and service requirement, these versatile

Components for blower stations
No matter whether for blower air or co
mpressed air, the
same rule applies: the air system should be considered
as a whole. No one understands this better than KAESER
KOMPRESSOREN, which is why we offer specifically
tailored air supply solutions for every need. Systems
and equipment include blower stations, master control
systems, air treatment and piping that work seamlessly
together to ensure maximum efficiency and reliability.

COMPACT Series –
Meticulous design and construction
Robust OMEGA blower block
Generously-dimensioned bearings
For pressures up to 1000 mbar(g), block discharge
temperatures up to 160 °C, wide control range with frequency-controlled operation, Q 2.5 rotor balancing for quieter operati
on, extended service life and minimal maintenance requirement.
Heavy-duty cylinder roller bearings absorb 100% of the
continuously changing radial gas forces. As a result, they
avoid the springing effect of self-aligning bearings and last
up to ten times longer with the same load.
Precision manufacture
Comprehensive sensors
Featuring precision straight-toothed timing gears (quality
5f 21, minimal backlash), KAESER blower blocks achieve
high specific delivery rates thanks to smaller flank clearances. Since the straight-cut gearing is not subject to continuously changing radial gas-forces, heavy-duty cylinder
roller bearings can be used.
A wide range of optional sensors and switches for monitoring pressure, temperature, speed, oil level and filters
ensures dependable blower operation and enables remote
monitoring and visualisation of operational status.

COMPACT Series
Exceptional versatility
COMPACT rotary lobe blowers are impressively versatile. If a robust machine without sou
nd enclosure
is required, the unit with block, intake and discharge silencer is the best choice. If additional sound
insulation is required however, then the highly-effective sound enclosure has your needs covered,
whilst the “high-end” version is available as a complete system with electrical control cabinet (star-delta
or FC operation) and an internal controller. This not only saves unnecessary installation costs, but also
enhances reliability.

SIGMA CONTROL 2
Blowers equipped with a sound enclosure, but without
integrated power switching equipment, feature a pressure
display and a filter maintenance indicator (pressure operation), or filter differential pressure switch (vacuum operation), as well as an optional remote thermometer for block
discharge temperature with an adjustable limit switch.
The SIGMA CONTROL 2 ensures
efficient blower control
and system monitoring. The large display and RFID reader
enable simple communication and maximum security.
Multiple interfaces provide additional flexibility for data bus
connection. The SD card slot makes updates quick and
easy.

Side-by-side installation
Even quieter
The package layout of rotary lobe blowers has been
designed to allow all maintenance work to be performed
from the front of the unit. This means that these compact
blowers can easily be installed side-by-side for maximum
space savings.
Highly-effective sound damping not only minimises machine noise via the sound enclosure; special absorption
silencers also help significantly to reduce fluid-borne noise
transmitted through the piping – a characteristic commonly
associated with speed-controlled blowers.

COMPACT Series
Variable speed control at its best
KAESER's COMPACT series turnkey rotary lobe blowers are equipped with
OMEGA PROFILE rotors to provide unbeatable reliabil
ity and energy efficiency.
Delivered ready for connection, complete with all sensors, star-delta starter
(or frequency converter) and CE/EMC labelling, they significantly reduce the
work and costs required for planning, installation, certification, documentation
and commissioning.
To ensure that the projected savings are actually achieved during operation,
KAESER quotes effective overall power consumption figures, as well as the usable flow rate, in accordance with the stringent tolerances of ISO 1217, Annexe C
or E (as applicable).

Wide control range
Always in control
Optimised matching of the blower block, drive motor and
frequency converter allows a wide control range to ensure
maximum efficiency in multi-unit operation without undershooting air demand or d
elivering cost-intensive excess air
supply.
No matter whether the blower system is equipped with
star-delta starter or variable speed control, users can
choose from various operating modes. This is particularly relevant if multiple units are to be incorporated into a
blower station.

High-quality control cabinet
Complete system EMC certified
The control cabinet houses only precisely matched electrical and electronic components from renowned German
manufacturers. When it comes to electromagnetic compatibility (EMC), all cables are safely shielded where required
(for machines with FC or star-delta starter).
The electromagnetic compatibility (EMC) of components
and of the complete machine has been tested and certified
in accordance with all applicable regulations.

COMPACT Series
The versatile vacuum generation solution
In their vacuum operation version, COMPACT series blowers feature an elastic connection on the
integrated intake filter silencer for connection to
the vacuum line, where a non-return flap can also be
installed. The safety valve layout
between the filter and blower
block offers protection
against short-term
overloading, for example
in the event of a blocked
intake line.

Connection options
Auxiliary exhaust silencer
With good ventilation, the compressed air can be exhausted diffusely into the room to atmosphere, or via an elastic
connection into a discharge line in order to feed the warm
air out of the room.
If exceptionally low noise levels are required, an additional exhaust silencer can be integrated in which the air is
repeatedly deflected past the insulating material.

Speed control
Separator tank
Using variable speed control, the OFC frequency converter adjusts flow rate to match the actual air demand of
the process application. Everything is delivered ready for
im
mediate operation, since all programming and parametrisation is carried out at the factory.
Specifically developed for use with milking technology
vacuum pumps, the separator tank provides outstanding
cleaning performance due to its centrifugal separation
action and combination of fluid and particulate filters. A
manual drain and automatic protection features, fitted as
standard, are available should the fluid level become too
high.

COMPACT Series
Special versions
Efficient, quiet, durable and versatile –
whether as a gas-tight blower for a recirculation system with nitrogen, or as a blower
with ATEX certification for potentially explosive ambient conditions, KAESER blower
packages are renowned worldwide for their
dependable performance, no matter what
the application may be. It is no wonder that
they are so highly regarded by operators
everywhere.
Image: DB 236 C
12
What is ATEX?
OMEGA PN: Nitrogen conveying
ATEX is derived from the French abbreviation for “ATmosphere
EXplosible”. The ATEX directive applies to all equipment and protective systems intended for use in potentially
hazardous and explosive atmospheres.
For pneumatic conveying of bulk materials in a nitrogen
atmosphere, leakages of any kind – including from the
rotary lobe blower – must be kept to an absolute minimum.
PN series blocks are therefore available with a wear-free
sliding ring seal on the drive shaft rotary transmission
lead-through.
Image: DB 236 C
Aquaculture – OEM versions
Outdoor installation
Blowers are required in aquaculture for various applications, be it for pneumatic conveying of fish feed in offshore
fish farms, or for biofilter aeration in land-based fish
farms. Consequently, COMPACT blowers are available in
versions that can be precisely tailored to meet the needs
of the specific application and equipment manufacturer.
Private labelling is also possible.
COMPACT blowers are often installed outdoors at wastewater treatment facilities. Stainless steel
rainproof covers
and premium-quality, powder-coated enclosures ensure
effective protection against the elements.

Equipment
Blower block
Controller (optional)
Robust and durable, energy-efficient OMEGA PROFILE
rotary lobe rotors, wide control range.
SIGMA CONTROL 2 with blower-specific software, large
display and RFID reader ensure effective communication
and enhanced security. Outstanding flexibility and easy
connectivity to centralised control systems via multiple
interfaces; SD card reader for quick and easy updates, as
well as for storing of operational data.
Drive motor
Proprietary brand, high-efficiency IE3 motor, three PTC
thermistors as standard; variable speed drive models coordinated with OFC frequency converter. Service is made
quick and reliable thanks to easy access central lubrication
points for motors with regreasable motor bearings.
Sound insulation
The system’s blower and motor cooling air is drawn in
from the cooler ambient surroundings outside of the
soun
d enclosure. Effective sound-proofing provided by
thick-walled lining with dense foam and damping louvres
over intake and exhaust openings. Wide-band absorption
silencer minimises process air pulsation downstream from
the blower block. This results in low residual pulsation and
therefore minimal sound transfer to downstream piping.
Power transmission
Highly effective automatic belt-tensioning system for
consistent transmission performance, V-belt safety grille,
belt-tensioning mechanism also acts as a motor lifting
device when changing the belt.
14
ACA aftercooler as accessory
High-efficiency ACA aftercoolers developed by KAESER
specifically for operation with rotary lobe blowers. They
reduce blower air temperature to a maximum of 10 °C
above ambient with minimal pressure loss and require no
cooling water. Electrical connection can be implemented
directly in the blower control cabinet.
