Omega Frequency Control
Most Com-paK models are also available with Kaeser’s Omega Frequency Control (OFC). This fully integrated variable speed drive
provides continuous blower speed adjustment to match the process flow to the demand. The OFC offers enhanced control with a
variety of signal inputs, outputs, as well as a Profibus connection. OFC is available as part of an integrated package on BB69C and
89C, CBC, DBC, EBC, and FBC models.
Wide control range
Kaeser matches the blower block, drive
motor, and variable speed controller for
optimal performance, which provides
better specific performance over a wider
range of flows. This ensures maximum
efficiency in multi-unit operation while
always meeting fluctuating demand.
Quality Control Cabinet
Integrated OFC and STC options
are housed in an isolated electrical
cabinet with dedicated ventilation. Our
electrical panels are well organized, with

Package Cooling and Enclosure Design
Parallel Cooling Concept
Kaeser’s Com-paK design separates
airflows for the blower, motor, and electrical cabinet. This ensures air is not
preheated before entering the blower,
which keeps the overall efficiency higher.
It also ensures the coolest possible air is
being channeled across the drive motor.
A dedicated fan ensures that regardless
of the operating speed of the package,
cooling air is flowing through the generous enclosure.
Extremely low sound and
vibration
All Com-paK models feature a standard
enclosure that is built for exceptional
noise reduction and easy access to
maintenance points. Heavy gauge construction and a powder coat finish make
it suitable for both indoor and outdoor
installation. Heavy duty dampers absorb
vibrations before they reach the base of
the unit or sound enclosure. They also
reduce stress on plumbing and wiring.

Service-Friendly Design
Kaeser has been a leader in creating fully packaged blowers that are reliable, durable, energy efficient, and simple to maintain. Our
line of Com-paK blower packages set the standard in the blower industry. In addition to a full scope of supply, these models feature an open package design to simplify routine maintenance. When you consider all the benefits of owning a built for a lifetime™
machine, it’s clear that a Kaeser Com-paK blower package will save you money, year after year.
Many features make our Com-paK models easy to service, including:
• A single front panel removes for complete easy access
to all major components
• Inlet filter requires no tools for servicing
• Automatic belt tensioner maintains drive efficiency and
eliminates frequent adjustments. Tension status is easy
to see at a glance and adjustments only take a few
minutes.
• Drain valves with gasketed caps simplify fluid changes
• Easy-to-read instrumentation
• High visibility sight glasses allow the fluid levels to be
checked at a glance from the front of the package
• Easily accessible motor grease fittings
• V-belt guard is easily removed, but provides full
protection
