Coalescing and Oil Mist Filters

Design, construction, installation and maintenance of coalescing filters and oil mist filters in all sizes and capacities.

What are coalescing filters?

Coalescing filters are devices for filtration oil mist: being humid, in fact, the latter cannot be usefully filtered with pocket or cartridge models, which would saturate too quickly. This type of filter instead uses the principle of coalescence, that is, the natural tendency of oily micro-droplets to aggregate; in the filter this principle leads to the formation of drops so large and heavy that they fall, leaving the air flow highly purified. Coalescing filters boast extraordinary efficiency.

Why are coalescing filters used?

Oil removal from air flows is an essential process in various industrial sectors, because the continuous deposition of oily micro-droplets on the surfaces of machinery leads, in the long run, to a decrease in their efficiency and to potential malfunctions.

Coalescence technology is among the preferred ones in the treatment of oil mist because of the substantial advantages it offers:

Very high separation efficiency:

even where the suspended oil particles are smaller than a micron, coalescing filters are able to retain percentages well above 90%, exceeding all emission thresholds dictated by law
Reduced maintenance needs:

not only do coalescing filters require minimal maintenance, but even when this is temporarily neglected their efficiency remains very high for a long time
Recovery possibility:

the oil droplets separated from the air flow do not undergo any molecular alteration, and can therefore be recovered and reused if the specific production process allows it

The reference standard for activated carbon filters is based on BAT (Best Available Technologies), which are the basis for the tables of the Italian Regions.

Application areas of coalescing filters

Coalescing industrial filters, as mentioned above, are used in numerous industrial fields where oil removal is necessary to preserve, first of all, the proper functioning of machinery.

A partial list cannot fail to include at least the following:

Mechanical machining with machine tools

Cold stamping of metals

Hot stamping of brass

Heat treatments of metals or metallic alloys

Rubber molding and post-vulcanization
