The problem of oil mists: what they are and how to solve it with AR Filtrazioni plants.
Oil mists are composed by airborne micro-particles of coolant.
This type of atmospheric pollutant is mainly focused in the mechanical and metal engineering industries, where works of turning, milling, grinding, grinding, trapping, drilling, bore, reaging, cutting, threading, threading, cold deformation of metal materials are the primary source.

Oil mists: what they are and how to hold them.
Oil mists are composed by airborne micro-particles of coolant.
This type of atmospheric pollutant is mainly focused in the mechanical and metal engineering industries, where works of turning, milling, grinding, grinding, trapping, drilling, bore, reaging, cutting, threading, threading, cold deformation of metal materials are the primary source.
The main causes of oil mists are due to the summation of these factors:
– evaporation of coolant – in fact, during extrusion and metal removal, the tool or cutter make contact with the worked piece. friction overheats them considerably, causing the evaporation of coolant and consequent fumes, oil mists and aerosols production.
– oil atomization – caused both by the high number of spindle/cutter/grinding wheel revolutions and by the use of high-pressure pumps for coolant on the machine tool. The resulting of these two elements, physically breaks down the fluids into particles, micro-dusts and micro-mists, making them volatile compounds.
– Evaporation of the containment tanks of coolant liquid;
– Airguns’ blasts for deburring or cleaning of pieces produced and machine tools.
– Atomization of oil caused by the high number of cutter turns
The problem of oil mists if not held
The volatility of polluting particles such as industrial fumes, oil mists and aerosols, whether they are solid or liquid, entails and creates various problems for companies, operators and machine tools.
First, in addition to the healthy air, they negatively affect the sanitary conditions of the operators, especially at the respiratory level, since particles smaller than 0.3 microns can reach the pulmonary alveoli, compromising the airways. Not only that, in contact with the epidermis, they create skin irritations, dermatitis and redness.
From a purely productive point of view, pollution in the workshop from micro-dusts and foil mists considerably reduces the productivity of the workshop and in particular the efficiency of machine tools, since the stratification of pollutants affects the precision and tolerance of measuring instruments, with the onerous consequence of having to increase maintenance on the most delicate components.
Dust, oil mists and aerosols, if unfiltered and purified, make the floor slippery, soil the surfaces of the machine tools and the walls of the shed, on which they settle.
Not forgetting any possible contraventions to existing regulations that impose a limit on the concentration of oil mists in the working
TLV limit Italian 5 mg/m3
ACGIH limit plus restrictive 0.5 mg/m3
