The mechanical solid matter filters for dust from LTA Lufttechnik are used to capture and separate all kinds of dust and fumes. They are used for simple industrial applications as well as complex industrial requirements and filtration according to special customer specifications. They can also be used for mobile systems or systems without a compressed air supply. Cartridge and pocket filters are available for removing harmful particles.
The polluted air is brought in via a suction line or with the aid of an extraction arm. It then flows through the container area where the decline in air speed results in separation of the heavier particles. Afterwards, the air mass flows through the filtration chamber with pocket filters or cartridge filters where fine pollutants smaller than 1 μm and aerosols are separated. The air exits via the ventilator chamber. Housing with another filtration stage and filter inserts adapted accordingly for the task at hand can be lined up before or after the ventilator chamber to filter out very fine dust or to separate various different gaseous pollutants and vapor. The filtered air can then be fed to the room from which it was extracted through a grid in the outlet or guided outside via a pipe fitted to the connection on the outlet cover.
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.
Mechanical dust filter including built-in cleaning function with mechanical-pneumatic actuation.
Automatic cleaning system with consistently high filtration efficiency, operational reliability over the long-term and additional explosion protection. Filter elements are cleaned by means of compressed air pulses.

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.
