Contec leadCONTEC, founded in 1972, is one of Germany’s leading suppliers of innovative filtration and separation systems for the power generating industry.

Oil mist filtration

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 (COMS) 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 COMS has a separation efficiency of 99.98%. There is no residual oil content below 0.1 mg/m³ and no particles between 0.2 µm and 0.9 µm in clean gas. contec Oil Mist Separators which was awarded the Environmental Technology Award in 1990.

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.

Oil mist separator options

The COMS is characterised essentially by:

  • High-efficiency filters prevent the emission of oil mist into the atmosphere
  • Filtering, separation and regaining high-quality lubrication oil including all its additives
  • Separation efficiency of 99.98%
  • Residual oil content below 0.1 mg/m³
  • High quality based on 40 years of experience and multiple well-tested and proven technology
  • Modular system allows a simple constructional adjustment to the respective application
  • Rapid and long-term supply of spare parts
  • Long service life and easy change of the filter elements
  • Automatic oil recycling system
  • Project-specific planning and construction
  • Various options

Long-service oil mist separator filter elements for easy maintenance

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.

Versatile oil mist separators

The main application of our COMS 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 40 years and are proud to have delivered more than 3,000 systems to customers all over the world.

  • Manual or automatic discharging of solid matter possible

A Long-Lasting Filtration System

It is not the elements themselves but the side-channel blower that determines the highest permissible operating temperature for the filter unit. The longer the filter elements are in operation, the more they become saturated with particles of solid matter.

How Oil Mist Separators Work

COMS comprise of a side-channel blower and the filter housing containing the filter elements. The side-channel blower causes negative pressure in the filter housing, into which the air containing oil mist is sucked.
