Oil Mist & Smoke Filtration
Oil Mist & Smoke Filtration

Absolent has established itself as a prominent and highly competent supplier of oil mist, oil smoke and dust filters.

Absolent's products clean contaminated air at the source. Typical such sources include a variety of metal working processes, die casting, cold forming and welding applications that generate oil mist, oil smoke and dust.  We have a strong focus on innovation, high quality and customized solutions.


We help you to save both energy and money!
Absolent has developed a simulation tool that shows you how you can achieve a clean work environment while saving up to 30% of your energy cost. With a few clicks, the app presents the energy saving and CO2 reduction that can be achieved by operating Absolent filter units with "EcoDrive". EcoDrive means that the airflow is controlled by the actual need. Savings get obvious, both in terms of environmental savings and in terms of money!.  A•saver can also simulate how much cleaner the work environment gets after the installation of Absolent's filter equipment.
Oil Mist Filters

Absolent's oil mist filter A•mist guarantees a high separating efficiency, which does not deteriorate even over long periods of operation. The filters can run continuously 24 hours a day.

The filter cassettes are self-draining and have a very long operating life, which means minimal servicing and maintenance costs. A•mist filter cassettes can usually be washed.
The filtered air can usually be returned to the premises, which saves heating or cooling energy, and the returned oil can be used for recycling.

A•mist oil mist filters are well suited to applications such as:
•  Grinding (cutting fluid emulsion)
•  Turning (cutting fluid emulsion)
•  Milling (cutting fluid emulsion)
•  Electrical discharge machining
•  Machining, using straight oil and moderate loads.

Contaminated air is sucked into the inlet (1) in the lower section of the filter unit and passes through an Absolent filter (3), where most of the oil particles are arrested. Before the filter becomes saturated with oil, the oil is drained down to the bottom of the unit that serves as a collection vessel.

The oil is then conveyed back to the machine, to a receptacle or to a central purification system (2).

The air passes on through another Absolent filter (4), where the remaining larger particles are arrested, and then through the fan to a HEPA filter (7).
By now, the air is usually so clean that it can be returned directly to the premises.

Oil Smoke Filters

A•smoke filters incorporate three filter steps whereat the two first filter steps are self-draining in order to allow continuous operation.
All our filters are fire-tested and have a low noise level.

Why use an oil smoke filter?
•  Oil smoke is hazardous to your health.
•  Oil smoke causes slippery floors and collects oil and dust on machines and walls.
•  Oil smoke can lead to coating in ventilation pipes, a potential fire risk, and in heat exchangers, so reducing the efficiency of heat recovery.
•  The cutting oil which drains from the filter can be reused.
•  The amount of oil smoke polluted air discharged must not exceed the prescribed limits.

Contaminated air is sucked into the inlet (1) in the lower section of the filter unit and passes through filter stage 1 (2), where the majority of the oil particles are trapped.Filter stage 1 gets saturated and the oil drops into the bottom of the filter unit, which acts as a collection container. From there, it is pumped (8) (accessory, not A•smoke20) or drained away.

The air passes through an additional Absolent filter (3), where the remaining bigger particles are filtered out and on via a HEPA filter (4) to the external fan. Generally the air is now free from particles and can be returned directly to the premises.

Compact Oil Mist Filters
A•mist6C works after the same principle as A•mist10C, but here, we always recommend the Hepa filter for an
exhaust level of 99.97%. The filter unit has analogue pressure gauges for the two filter stages.

The oil is then conveyed back to the machine, to a receptacle or to a

Absolent's A•mist10C is extremely effective for cleaning oil mist. Choose between three different exhaust
levels depending on your local particle emission regulations or company policy. Take total control of your
working environment with A•mist10C, the first compact oil mist filter with an electronic LCD monitor!

Electronic Manometer
A•monitor is integrated in the service door of most A•mist and A•smoke filter units as standard. With our new A•monitor retrofitting kit, it is now possible to upgrade existing ODF and ODR units or to place a second A•monitor at a more convenient location, for example if the A•mist or A•smoke filter unit is placed high up and it is difficult to read the integrated monitor.

Optical display of the pressure drop over the filter stages

The present pressure drop over each filter stage is monitored.

LED indication

A green LED lamp is lit as long as the filter cassette works within the preset pressure range. When the yellow lamp lights up, the filter stage needs to be replaced or washed. Call your service contact for advice. When the red LED lamp lights up, the pressure drop over the filter stage is too high, and the filter unit might give a reduced air flow.

Hour counter device

An hour counter device is also included in our standard equipment. It shows the total operation time of the filter unit measured in hours.

Alarm

On the transformer circuit, there is an alarm output that can be used for external alarms (maximum 1A). If any of the filter stages reaches alarm level (red LED), the alarm output closes.

Applications

Absolent filters offer a high degree of separation, long service intervals of up to several years and can run continously 24 hours a day, seven days a week with a minimum of maintenance.  Even in tough applications such as:
