Air filtration & heat recovery for textile finishing

As leading solution provider KMA offers energy efficient exhaust air filter system for the textile industry. The application of an KMA exhaust air filter system is pursuing two goals: Clean air in the textile industry and the reduction of energy consumption through heat recovery.

Depending on the textile finishing process, different pollutant emissions arise at the stenter frame and need to be treated. In addition to fumes, oil smoke and aerosols, also wax particles, formaldehyde, synthetic resins or fluorocarbon resins have to be separated from the contaminated exhaust air. KMA exhaust air filters specialize in these complex requirements of exhaust air purification and are designed for the following processes in textile finishing:

Heat treatment

  • Thermosetting
  • Raw material thermofixation
  • Easy care equipment finishing

Wet finishing

  • Fluorocarbon finishing
  • Flame-retardant finish
  • Silicone finishing
  • Synthetic dispersion


  • PVC coating
  • Nonwoven coating
  • Foam coating
Energy recuperation: Our contribution to economic efficiency

Energy recuperation: Our contribution to economic efficiency

Energy recuperation is an effective instrument to reduce operating costs in the textile industry challenged by energy intensive production processes. In effect energy costs can on average account for more than 20 percent of overall operating costs in the textile industry.

KMA Filter make use of the valuable heat derived from the productional exhaust air and reduce the energy consumption of the production facilities thanks to the integrated heat recovery system.

Excellent air quality in accordance with legal requirements

Excellent air quality in accordance with legal requirements

The exhaust air is polluted by pollutant emissions as a result of the chemical treatment of the textile during the textile production and thermo fixation.

Air pollution is in contrast to legal requirements and sustainable business policy. The electrostatic filter cells of KMA Filter allow high-grade separation even when faced with highly polluted exhaust air and sticky or greasy aerosols.

Less energy consumption means less costs!

The exhaust air from stenter frame systems consist to a considerable extent of dust and oily aerosols but also of a valuable amount of heat from production processes. Even the separation of wax particles in textile finishing need to be concidered. Nowadays, the textile industry is confronted with strict regulations in terms of occupational health and safety as well as environmental protection.

KMA ULTRAVENT® exhaust air filter systems accommodate these requirements already: they are suitable for separation of oily, greasy or pasty aerosols from the exhaust air and are characterised by high separation efficiency, durability and very low energy consumption.

Due to the integrated heat recovery technology, the textile manufactory can also handle ambitious goals for improving its carbon footprint and put high amounts of energy savings into practice. Depending on the mixture of exhaust air the ULTRAVENT® electrostatic filter cells can be combined with additional filters as UV light tubes, activated carbon or gas scrubber . The oil contained in the exhaust air is separated and discharged via a drainage opening.

The advantages at a glance!

KMA exhaust air filtration systems fit to any production process
With KMA AAIRMAXX® and KMA ULTRAVENT® you will master any problem caused by waste air and you remain free to choose the production process.
Refurbishing an old plant with KMA exhaust air filters
KMA exhaust air filtration systems have zero negative impact on processes taking place during production. Existing production plants are able to continue operation without modifying their original design and will in turn meet the requirements of the Bundes-Immissionsschutzgesetz (BImSchG).
The operating costs of a KMA exhaust air filtration system are considerably low
KMA exhaust air filtration systems use the most advanced, most cost-effective method for waste air purification by combining the techniques of electrostatic precipitators with gas scrubbers. In comparison to conventional methods of post-combustion, energy costs are decreased by up to 80 percent.
High filtration efficiency
KMA exhaust air filtration systems ensure compliance with the emission limit values according to the TA-Luft* regulations and the VDI** directives. KMA systems are designed according to the high requirements of the German legislation relating to workplace safety (BG) and Federal Imission Control Act (BlmSchG).
Operation almost free from wear
KMA exhaust air filtration systems are not vulnerable to thermal wear. More than 3,000 systems installed in numerous manufacturing works - some with over 50,000 hours of operation - prove this in a striking manner.
Automatic filter cleaning: Unmatched in convenience
The convenient automatic filter cleaning system cleans the modules in regular intervals, which ensures the durability of the filter modules and low maintenance operation.
