When the oil mist clears

Suitable filter concepts for maximum occupational safety

When the night shift begins and new staff come on shift at the metalworks, the machines have already been running the whole day.

They can tell by the feeling under their feet. Milling, turning, and grinding leaves behind metal shavings and dust as well as a fine sticky, oily layer on the ground and plant components.

This oil mist occurs wherever cooling lubricant is used to protect tools and materials from heat and ensure clean processing. High workpiece temperatures and the rotary momentum of the tools vaporizes cooling lubricant, creating tiny droplets. If the air is not effectively extracted and filtered, these droplets are dispersed throughout the working environment.

Downtime
and mucous membrane irritation

Whatever makes work for the cleaning team is also a safety risk for both people and machines. Oil deposits pose a problem for sensitive electronic control units as they can cause short circuits, have a negative effect on conductivity, and eventually cause plant downtime.

The droplets in the air contain oil and microscopic metal particles, as well as emulsifiers, preservatives, and anti-foaming agents — all ingredients in cooling lubricants. Breathing in these droplets can lead to irritation of the mucous membrane and respiratory tract as well as skin inflammation.

If a thin film of oil occurs on the floor, there is also a risk of slipping, which endangers occupational safety in general.

Tailored concepts
for improved occupational safety

Preventing oil mist requires effective cleaning of the extracted air. The solution usually comprises multi-stage filtration systems that are customized in accordance with the on-site conditions, and which separate oil mist and other particles from the air using a coalescence separator and downstream filter elements. The result is clean air that poses no risk to people, machines, or the environment.
