The mechanical particle filters for dust from LTA Lufttechnik are used to collect and remove dust and smoke of any kind. The filtration systems are used for simple industrial applications, but equally for complex industrial requirements and filtrations with special customer specifications. Cartridge and pocket filters are available for cleaning harmful particles. The contaminated air is collected at the exhaust openings or with the help of an extraction arm, and led to the filtration system in a piping system.
Then the contaminated air flows through the housing, where gravimetric removal of the larger particles occurs due to the decreasing air velocity. The air then flows through the filter chamber with filter pockets or filter cartridges, in which contaminations smaller than 1 μm and aerosols are removed. The air reaches the air outlet via the blower chamber. For the removal of ultra-fine dust or a huge variety of gaseous harmful substances or steam, a further filter chamber with suitably adapted filter elements can be installed upstream or downstream of the blower chamber. Finally, the clean air is led via the air outlet either into the collection area or outdoors via a piping system.
Automatic cleaning system with consistently high collection efficiency and permanent operational reliability. The filter elements are cleaned by a compressed air pulse.
Mechanical dust filters including built-in cleaning function with mechanical-pneumatic actuation.
The filtration systems are equipped with additional explosion protection. For example, the filter chamber has protective measures regarding design. Furthermore, a three-phase blower in an explosion-proof design is used.

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.
