contec Oil Mist Separators (COMS)/Oil Mist Eliminators for the extraction and filtration of oil mist are used for large-scale compressors, gas and steam turbines, generators and other equipment with oil systems to ensure clean, oil-free exhaust air. 99.99% of solid and liquid particles and aerosols down to 0.1 micron are removed and high-quality oil can be regained.

contec COMS are equipped with a side channel blower that generates adjustable negative pressure in the oil systems. This prevents the leakage of oil mist from the bearings, shaft guide and crankshaft ventilation systems. As the filter elements have a long service life and an automatic oil recycling system, they require little maintenance.

The core of the COMS are the glass fiber filter elements developed especially for these applications. The two-layer design with integrated reinforcement fibers optimizes the coalescence effect and ensure a constantly high level of oil separation. The degree of efficiency is 99,99% at a droplet size of 0.1 micron, which means that the exhaust air is far cleaner than that required by German TA regulations of clean air.

For that reason COMS have been awarded with the Environmental Technology Prize for 1990. Due to their very compact design, contec Oil Mist Separators are also easy to use under all difficult or restricted spatial conditions.

Installation of the Oil Mist Separators (COMS)/Oil Mist Eliminators on:

  • Lube oil systems (LOS) of gas and steam turbines
  • Fluid grinding plants
  • Vacuum pumps
  • Spray pattern test bench
  • Rotating machines
  • Compressors
  • Large-scale compressors
  • Crankdrives
  • HE fluid grinding plants for diesel injection components

Technical task of the COMS:

  • Filtering, separation and regaining high-quality lubrication oil including all its additives

Operational task of the COMS:

  • Avoiding oil leakage (at bearings etc.) by creating a permanent slight negative pressure in the lube oil system

Global/environmental task of the COMS:

  • High-efficiency filters prevent the emission of oil mist into the atmosphere

Protecting the environment by reducing oil mist emission down to < 3-8 mg/m³, cleaner than the German TA regulations of clean air and long­term protection of the environment
