Heavy duty cylindrical bearings absorb the continuously changing radial gasforces exerted onto the cylinders and last up to ten times longer than axial thrust bearings under the same load conditions. Oil slingers on both gear and drive ends of the blower provide lubrication to the bearings, gears, and input shaft seal to ensure long service life.

rotor sealing strips reduce sensitivity to contamination and intermittent thermal overloading.

Omega Frequency Control Most Com-paK models are also available with Kaeser’s Omega Frequency Control (OFC). This fully integrated variable frequency 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 components clearly labeled.

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
