The TA Luft defines limit values of airborne pollutants in exhaust air operation, including the total dust volume, as well as fine dust content. It is important to comply with either the mass flow or mass concentration limits as set forth. In this brochure, Keller Lufttechnik lists some limit values for you.
The German regulation 42. BImSchV applies to evaporation coolers as well as wet scrubbers. It regulates the maximum allowable legionella concentrations and defines preventive measures.

Regulation VDI 2262-3 provides information about air pollution control measures to minimize exposure to pollutants in the workplace. It is particularly important for clean air recirculation because the limit values are strictly defined for this purpose.
The TRGS 900 includes a list of materials with limit values for the workplace. Compliance with these limit values will safeguard the health of workers who are exposed to inhaled pollutants. The air quality in the workplace must demonstrate that the limit values are not exceeded. Therefore, reliable extraction systems and air pollution control efforts are required in many cases.
Since the beginning of 2012 the current TRGS 560 diective applies to air recirculation of carcinogenic dust. Mandatory measures and levels of separation are specified here for potential air recirculation.
Regulation TRGS 528 applies to welding or cutting of metals that may produce hazardous gaseous or particulate emissions. Welding of stainless steel produces carcinogenic Cr(VI) compounds.
This regulation applies to the grinding, brushing and polishing of aluminum at processing machines and related facilities. It refers only to the associated fire and explosion hazards. As a rule, wet scrubbers or dry separators with constructive explosion protection are recommended for these applications.
This regulation is for the handling of magnesium, especially during processing, filling, decanting, removing, or storing. The magnesium can occur as shavings, dust or sludge. As a rule, wet scrubbers are used for these applications.
Working in enclosed spaces can generate increased concentrations of hazardous substances. This DGUV regulation provides basic information regarding ventilation and air conditioning systems.
The explosion protection directive 199/92/EG (known as ATEX 137) includes basic safety requirements regarding the risks posed by explosive operating environments. The focus is on the explosion protection document which also specifies the safety zones for operators.
Guideline 2014/34/EU of the European Parliament and of the Council (commonly referred to as ATEX 114) is aimed primarily at manufacturers. The guideline pertains to protection systems and any machinery and units that are located in a potentially explosive environment. Included in this context are both electrical and non-electrical equipment that may have their own potential ignition source.
This European standard is a customary explosion protection document. It sets out procedures for detecting and assessing hazardous situations that can lead to explosions, and describes appropriate planning and manufacturing safeguards.
Electrostatic charges can create ignition sources, which in turn can set off dust explosions.The TRBS 727 outlines precautionary measures such as grounding.
The VDI 2263-6 Guideline specifically pertains to dust extraction systems. To adopt suitable protection measures, Keller Lufttechnik complies with the explosion/fire protection measures described herein.
