The inside-to-out flow pattern combined with a positive O-Ring seal arrangement guarantees high-efficiency contaminant removal and holding capacity, prolonging service life. The filter cartridge is designed for efficient element removal and replacement and ensures that no trapped particulate accidentally falls into the clean side of the filter housing.

This revolutionary final stage MAXUM Multiple Vee Panel design uses a new concept to create eight (8) panels in a “Vee Formation”, that greatly increases usable media area, resulting in lower initial pressure drop, increased dirt holding capacity, longer service life resulting in the overall reduction in operating costs.
Final stage design was Optimized through Computational Fluid Dynamics [CFD]
A proprietary water resistant microglass media presents a “dual-layer” barrier to particles which penetrate the prefilters.
The MAXUM panel utilizes a rugged Polystyrene frame that is not only light weight, but corrosion proof and fully incinerable.
The features and benefits of this new technology are:
Superior Performance – 99.97% removal of 2 microns and over 90% removal of 0.4 microns protects the performance and life of rotating equipment.
Sealing – Incorporates a pre-mounted seamless polyurethane foam gasket that ensures positive seal, eliminating chance of particulate by-pass.
Extended Element Life – More available surface area with the MAXUM Primary design doubles dirt holding capability, extending element life and reducing element replacement costs.
Sizing Flexibility – The MAXUM is capable of flowing up to 3,000 SCFM rather than the standard 2,500 SCFM. That is a 20% increase in capacity without penalty of added pressure drop. This sizing flexibility allows for a smaller housing and lower capital expense.
Today, the protection of turbo machinery is measured in microns, which is one reason the world’s leading manufacturers continue to rely on Dollinger’s high-efficiency filtration products. The Maxum filter represents our latest innovation in contamination protection
to improve the performance and efficiency of your high-speed turbo machinery.
As the pioneer in air intake filtration, Dollinger continues to solve the most demanding filtration problems for industry. Turbo machinery is precision engineered to perform in some of the most hostile environments in the world.
Each machine is custom engineered to extract maximum performance out of every kilowatt of energy they consume. Precision balanced shafts and impellers rotate at speeds of up to 70,000 revolutions per minute. At that kind of speed, otherwise harmless drops of water or grains of sand can cause catastrophic results. Quality filtration offers protection that can’t be beat.
Contaminant removal specifications speak in terms of microns. The deeper the pleats, the more surface area there is to extracted and contain contaminants. The longer between filter panel changes, the better the productivity of the machine and the lower the cost of operation.
That is why the world’s leading manufacturers continue to rely on high-efficiency Dollinger filtration products like TURBO KLEEN. The TURBO KLEEN filter represents our latest innovation in contamination protection for your high-speed turbo machinery.
Providing the maximum protection from the finest dust, Sonic Flow final air filters have been selected by turbine operators across the world.
Filter Media
Filter Construction
No filter can promise to eliminate every cause of downtime. But there is one element reliable enough to prevent most causes of unscheduled equipment shutdown due to filter failure or premature plugging.
The Dollinger element incorporates the efficient radial finned design which provides the largest filtration area for a given element size. This increases dirt-holding capacity, minimizes pressure drop and results in an extended service life
The filter media support structure utilizes carbon steel or alternatively, stainless steel. The standard element design ensures its integrity up to a differential pressure of 50 psid. Special designs are available for applications which demand higher differential capabilities.
Filter Media
Dollinger offers an extensive range of synthetic and natural fiber filter media suitable for use in most processes. In addition, stainless steel mesh media can be incorporated in the existing element design for more demanding applications. In most instances the Dollinger filter element can be cleaned and reused many times. This feature is especially beneficial in applications having high levels of contaminant.
Inter-Changeability
In the event of changing process conditions following installation, it is possible to interchange elements to vary the degree of filtration.
Selecting the right filter medium depends on specific operating conditions. Dollinger therefore offers a wide range of filter media components including: natural and synthetic materials, such as polyester, glass fiber (woven or needle-felted), PTFE, cotton and stainless steel. We supply media for retentions up to 99.97% efficiency at 0.3 microns.

TURBO KLEEN™ MVP-6020-2424-518
The TURBO KLEEN media features a graded pore structure, which maximizes dust-holding capacity and extends the time between filter changes, even under high dirt loading conditions. High efficiency ASHRAE/EN tested media maximizes the output of turbo machinery by removing microscopic particles, which can foul and damage compressor blades.
Strong reinforced glass fiber media guarantees reliable filtration, even under high velocity and turbulent operating conditions, with no media shedding. A highly permeable filter media operates at low delta P resulting in improved performance and efficiency of turbo machinery.
The filter frame is a 100% polymeric and lightweight design that’s totally corrosion resistant and disposable by incineration. The pre-mounted, seamless gasket creates a positive seal for superior leak prevention.
The Dollinger Al- .128 two-stage filter/silencer is designed to efficiently remove submicron dust, dire and other airborne contaminants from the atmosphere using two separate stages of panel filter elements – protecting axial and centrifugal compressors and blowers and, at the same time, reducing compressor in let noise.
The Al- 128 is designed to be installed either directly on the compressor or blower inlet, or on remote inlet air piping. Dollinger manufactures 18 standard models, available with capacities up to I 02,000 ml/hr and bottom outlets ranging in size from 150 to 900 mm in diameter. The standard silencing feature provides sound attenuation up to 17.5 dB(A). Larger capacities are available upon request.
