The expert in food processing exhaust air treatment.
KMA AAIRMAXX® ESP tube electrostatic precipitators are highly effective in separating coarse and fine particles, solid substances and liquid droplets from the air. The smoke and dust particles are led vertically (from bottom to top) through the filter body. A stainless steel iIonization electrode inside the separating tube forces the aerosols and particles against the metal wall of the filter body.
From there the separated substances can be removed continuously (e.g. through a fine water film) or discontinuously (through knocker, steam, CIP-water). In this way, also sticky or greasy substances as grease, sticky dusts and similar can be removed from the air without clogging the filter system. AAIRMAXX® electrostatic tube filter are often used for exhaust air with higher concentrations of emissions.

For the exhaust air filtration it is very important that the energy consumption of the filter medium is very low despite the high efficient separation. Due to the stickiness of the substances to be separated in the food processing industry (e.g. in smokehouse consisting of grease and tar) classic “filter media“ cannot be used as separator (cassettes, bag filter, cartridge filter etc.). They would quickly plug, which causes high pressure loss and thus elevated energy consumption and high follow up and replacement cost.
The KMA AAIRMAXX® system consists of a large electrostatic filter tube, which does not allow resistance or pressure losses. Thus the exhaust air can in principle pass the KMA electrostatic filter without hindrance. The exhaust air to be cleaned is led vertically through the tube, which is equipped with an ionization electrode inside. The ionization electrode generates a strong electric filed with very little energy expenditure. Particles like dust, tar and water droplets are charged by electrostatic energy and settle on the inner surface of the tubes or flow down to be collected in a collecting vessel. To avoid the accumulation of emissions inside the AAIRMAXX® System and to guarantee the high separation efficiency of the electrostatic filter, it is cleaned regularly by the automatic cleaning system. These features make the KMA Electrostatic Filter to an economic, low-maintenance and long-lasting filter medium for diverse applications in the industry.
For difficult odor problems the energy efficient AAIRMAXX® electrostatic filter tubes can be combined with KMA scrubbers or activated carbon filters.
KMA AAIRMAXX® exhaust air filtration systems are mainly used in the pharmaceutical and food processing industry.
AAIRMAXX® Systems are characterized by the AAIRMAXX® ESP Electrostatic Filter Tube. Its design is entirely different from the ULTRAVENT® electrostatic filter cell and is especially suitable for viscous resp. highly concentrated emissions (e.g. tar containing exhaust air of smokehouses). For smaller exhaust air volumes AAIRMAXX® ESP electrostatic filter tubes van be also used in the metal processing. Here the electrostatic filter tube works on the principle of layer ventilation.
Depending on the type of exhaust air KMA AAIRMAXX® exhaust air filtration systems can be composed of electrostatic filter tube, gas scrubber and activated carbon filter.
