Extraction of oil mist and aerosols

Extraction of oil mist and aerosols

Oil mist extraction is an application characteristic of CNC machining using a cooling emulsion. When we are machining with high-speed tools, a large amount of thermal energy is released and for this reason a cooling emulsion is used to cool both the tool and the workpiece. In the CNC machine, the cooling emulsion is sprayed in the form of an aerosol formed by micro-droplets of the cooling emulsion. At the same time, the emulsion evaporates due to high machining temperatures. Evaporation of the emulsion produces oil fumes. In the absence of extraction of the CNC machine, oil emulsions and vapors are spread into the production hall through leaks in the machine cover.

Oil mist extraction can be realized locally, where each CNC machine is equipped with its own oil mist separator. Central aerosol separators are used for the central extraction of oil mist from a group of machines, equipped with an exhaust fan with the possibility of controlling the extraction power. For individual exhaust machines, we install automatically controlled dampers, which are controlled according to the CNC machine used. The suction line of the oil mist extraction system must be tight so that oil condensate does not flow through the pipe connections.

Mechanical mist separators


The devices are designed to separate emulsion nebulae formed during machining. The principle of separating oil droplets from the air is mechanical. The device does not need any disposable filters. Aerosols are separated using a stainless steel cloth and a separating lamella. The device is supplied as a compact unit with a fan designed for immediate connection. We supply the filters with an integrated electrical switchboard for the possibility of controlling the fan speed. We supply the device with suction both from the left and from the right. The bottom is designed as a watertight oil sump with a nozzle for connecting the separated emulsion drain hose. All filter cartridges can be cleaned and it is not necessary to use any disposable cartridges.

Electrostatic mist separators


The device is designed to separate oil nebulae generated during machining. The principle of separating oil droplets from the air is mechanically and electrostatically. The device does not need any disposable filters. The aerosols are separated using a stainless steel cloth, a separating lamella and an electrostatic precipitator. The device is supplied as a compact unit with a fan designed for immediate connection. The motor is electronically controlled with stepless speed control for suction power up to 1400 m3/h. All filters, including the electrostatic block, can be cleaned and it is not necessary to use any disposable installations.
