New Dollinger MAXUM Panel Filters for Turbines and Compressors

Dollinger has introduced a new high efficient air intake panel filter to protect turbines and compressors. The new Dollinger MAXUM panel filter features their continued innovation in filtration to improve the performance and efficiency of your high speed turbo machinery.


Dollinger Primary Stage MAXUM Air Intake Panel Filter

• High efficiency ASHRAE/EN-tested media

• Maximum dust-holding capacity for extended service life

• Rugged, high burst pressure design

• A novel concentric dual-gasket system virtually eliminates any chance for filter by-pass even under the most severe operating conditions

• Light weight polymeric frame is completely corrosion resistant and disposable by incineration


This revolutionary final stage MAXUM Multiple Vee Panel design uses a new concept to create eight panels in a “Vee Formation”, that greatly increases usable filter media area. The Multiple Vee design allows for lower initial pressure drop, increased dirt holding capacity, longer service life, and overall reduction in operating costs.

Dollinger Final Stage MAXUM Panel Filter

Final stage design of this new technology in filtration 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.
