Electrostatic filtration systems for oil and emulsion mist are the ideal solution for sustainable production in industry and skilled trades. The pre and post-filters are fully washable so they can be reused. As highly flow-optimized solutions, the electrostatic cooling lubricant mist filters have a long service life and offer sustained, constant performance.
In electrostatic filtration systems for cleaning and extracting oil and emulsion mist, the first step involves extracting the polluted air via a pre-filter. This separates coarse particles larger than 3 µm and the pre-filter also protects the downstream filter elements from foreign bodies. Next, an electric field gives the incoming neutral aerosols a positive charge in the ionizer. These positively charged particles are deflected by collector plates (negative charge) and separated out in the downstream collector. The neutralization filter neutralizes any remaining positively charged dust particles in the penultimate step. Optional post-filters, such as those for smoke or odors, can also be fitted. The fan sucks the air flow through the air filter via the connection opening and coveys the purified air out of the housing.
Automatic cleaning system with consistently high filtration efficiency and operational reliability over the long-term. This LTA automatic system cleans using the cooling lubricant in the machine (e.g. lathe or grinding machine) without chemical additives or diluted solution. The CIP automatic cleaning system for machine tools permanently reduces material, personnel, energy and disposal costs.
Inexpensive entry-level air filters which do not have an interface to the machine but still offer all the advantages of electrostatic filtration systems.
Compact filtration systems for use in situations with limited space.
Electrostatic filtration systems, especially for machining magnesium.

LTA assumes a 250-fold per cubic meter and hour rate as a guide for air exchange for cooling lubricant. As an example, a machining area of 5 m3 in the machine and automatic loading result in a required effective suction capacity of approximately 1,250 m3/h. If the machine is manually loaded, a faster air exchange rate is required. Whatever the requirement, LTA’s filtration experts will find the perfect solution. The recommended collection rates lie between 2.5 and 10 m/s.
Electrostatic oil and emulsion mist filters are generally recommended. If emulsion is used as a cooling lubricant, then a mechanical air filter can also be used up to a concentration of 5%. If oil is used, then the use of a mechanical filtration system is also possible up to an oil flash point of 120°C. In the case of cooling lubricant pressures of up to 40 bar, one-step air filters can be used, for pressures greater than 40 bar, the two-step versions of the electrostatic air filters are recommended for industry and skilled trades.
In the case of dust and fumes, a 100 to 300-fold per cubic meter and hour rate is assumed as a guideline for air exchange. The experts at LTA will plan the right filter for you and your needs. As an example, a machining area of 4 m3 in the machine and automatic loading results in an required effective suction capacity of approximately 400 to 1,200 m3/h. The recommended collection rates, or welding and brazing for example, where pollutants only have low airspeeds in calm air are 0.5 to 1 m/s. If the pollutants have higher airspeeds in moving air zones, such as during grinding or sandblasting, then a collection rate of 2.5 to 10 m/s is taken into account.
If the dust is oily or moist, filtration can be ensured by an optional pre-coating unit or an electrostatic filtration system. Odors and other small particles can be removed by an additional post-filter.
