Absolent Mist Collection

Absolent cleans contaminated air at the source. Typical such sources are various metalworking, die casting, cold forming and welding machines that generate oil mist, oil smoke and dust. With over 20 years of experience in this business, we offer the highest quality and genuine know-how in every part of our organisation. We have a strong focus on innovation, high quality and customized solutions.

What Is Oil Mist?

Oil mist consists of airborne oil droplets. The size of these ranges anywhere from 1 – 10 µm. This means they are the same size as bacteria. Oil mist is normally formed in several processes where oil or oil based coolant is used. This is often in the manufacturing industry where oil mist arises when these fluids are used as coolant, for lubrication or chip removal, for instance during turning, milling, grinding and drilling. You may also encounter oil mist in plastic industry, rubber and textile industry, in steel and rolling mills and in conjunction with hardening (induction).   The amount of oil mist in air is measured in mg/m3. Different countries have different threshold limits for what is allowed in a workshop. Absolent and our representatives are more than happy to assist with measurements and design a project that will suit your workplace perfectly.

How To Capture Oil Mist

The most common and effective way to capture oil mist  is to extract the contaminated air as close to the source as possible. The more enclosed and air tight the process is, the less air quantity and energy is required. If a filter unit from Absolent is installed it will effectively extract the air from the enclosure and protect the worker and the environment from the contamination.  If the machine is partly open, Absolent or our representatives can assist you with accessories, hoods or enclosures that will make capturing the polluted air both easy and energy efficient.

Absolent Has The Solution

Air contaminated by oil mist and/or oil smoke passes into the bottom part of the filter unit where the filtration begins. The big, heavy particles are unable to follow the air that is flowing upwards. These oil droplets fall down and are collected in the bottom section and pumped out of the filter unit. The oil can then be returned back into the machine, to an oil collection barrel or to a central cleaning for re-circulation.  The remaining pollution passes through the first Absolent filter cassette where oil particles are captured and then drained downwards, away from the cassette. This is what we call the “Catch and Release” principle. This is, of course happening while the machine is operating at full speed. The filter unit is designed for 24/7 operation so there is no need for downtime to drain or clean the cassettes which allows you to fully focus on your manufacturing.  Depending on what filter unit you have the air is sometimes passed on through yet another filter cassettes where most of the remaining particles are filtered away. The Absolent filtration process always ends with a HEPA filter class H13, which ensures that the air is 99,97% free from harmful particles larger or equal to 0,3 microns.  When the filtration process is done what happens to the air depends on the local regulations. It can either be returned directly to the premises or be passed via a heat exchanger before it’s returned back into the workshop.
