CONTEC - Exhaust Air and Vacuum Filters and Oil Mist Separators: Clean Solutions on Demand

CONTEC, founded in 1972, is one of Germany's leading suppliers of special filter systems for the power generating industry.


Experts know all about the problem: high concentrations of oil mist from industrial production result in health risks and environmental pollution. This applies particularly to large workshops and factories in which rotating machines such as wheel mechanisms, turbines, turbo units or compressors for producing energy or compressed air are used. The problem has prompted governments to stipulate maximum pollution levels for these plants.

CONTEC has the solution: CONTEC oil mist separators extract the air containing oil mist and discharge it through the filter. With CONTEC oil mist separators levels of oil mist can be reliably maintained. The separators are 99.99% effective, producing clean, dry exhaust air with a droplet size of 0.1µm.


Oil mist separators supplied by CONTEC comply with all of the legal requirements, with air quality results better than those required by the German TA regulations for clean air.

All systems can also be delivered according to US standards, including with NEMA motor / blower units from 1/2HP cURus, 208V-230V/460V - 60Hz to 71/2HP 208V-230V/460V - 60 Hz, TEFC-AMT, and CSA approval. Flow rates from 20m³/h to 670m³/h are available. The biggest unit we are currently constructing is designed for a flow rate of up to 2,400m³/h.


All CONTEC oil mist separators can be supplied:

  • With motors according to customer requirements
  • With by-pass of external ventilation
  • With by-pass and non-return valve
  • According to special blower and motor specifications
  • With further instrumentation or measuring gauges
  • For special frame constructions
  • With additional motor / blower units
  • For special pipe systems
  • Made of stainless steel (304 / 316L / 316Ti)


The long service life of the oil mist separator filter elements (at least one year) and the automatic recirculation of the oil mean that the system requires little maintenance. Thanks to the quick-action fasteners on the cover, filter elements are easy to replace.

Thanks to their extremely compact design, CONTEC oil mist separators are also suitable for use in difficult installation positions.


The main application of our CONTEC oil mist separators is on gas or steam turbines, generators, turbo-compressors, gas or diesel engines in order to prevent leakage of oil from the lubrication system through the bearings.

We have been building and improving oil mist separators for more than 15 years and are proud to have delivered more than 1,500 systems to customers all over the world.
