FUMES | DUSTS | VAPOURS

Welcome to "Die Luftreiniger" Dear customers and partners of TEKA, Welcome to our world – the world of air purifiers! Because clean air is not just a profession for us, it's a vocation. While the protection against air pollutants at the industrial workplace used to be considered a generous gesture by the boss, the use of innovative extraction technology for modern companies is commonly accepted as a necessity nowadays. In times of a shortage of skilled labor, the targeted energy turnaround and high requirements of clean production processes, employee satisfaction and the Clean Factory become...

Good to know What is dust/fume? Dust/fume is finely distributed solid particles in the air, German framework regulation Ordinance on Hazardous Substances (GefStoffV) 1 which are caused by thermal processes such as welding. When it came into effect on January 1st, 2005, the Ordinance on Hazardous Substances restructured the occupa- What causes dust/fume? tional safety for activities involving hazardous substances In welding technology dust/ fume and thus hazardous as implementation of several EC directives. Welding fume is considered a hazardous substance, thus the Ordinance on Hazardous...

Air circulation when dealing with carcinogenic substances the required effectiveness. Instructions on the fresh air fraction If activities are carried out in a working area involving ventilation – ventilation measures". (2) At workplaces where hazardous substances of category 1 or 2 which are carcino- welding work or allied processes involving the emission of genic, mutagenic or have a negative impact on fertility, the carcinogenic or mutagenic substances or substances toxic to extracted air there must not be returned into the working reproduction of category 1 or 2 are performed...

Die Luftreiniger Good to know Occupational exposure limits Occupational exposure limits serve to protect the employees and their health against the dangers of inhalation of substances (TRGS 900). They came into effect in 2005 and replaced the maximum workplace concentration values that applied until then. TRGS 400 clearly states that the employer needs to carry out an assessment of the risks and that the necessary protective measures must be taken before starting the work with hazardous substances (§ 3.1(2)). The employer always has the overall responsibility (§ 3.1(6)). TRGS 402 informs...

Good to know Types of filters Prefilters and particulate filters are classified into 17 different filter classes according to their separation efficiency ranging from the coarsest filter to the finest filter U17: ■ ISO Coarse: COARSE DUST FILTERS ■ ePM10, ePM2.5, ePM 1: FINE DUST FILTERS ■ E10, E11, E12, H13, H14, U15, U16, U17: PARTICULATE FILTERS (ISO 16890 and EN 1822-1:1998) Depending on the norm the initial separation efficiency or the fractional separation efficiency are used as a performance criterion under standard load. Initial separation efficiency: Ratio between the passing and...

Good to know Particle sizes Particles having a size between 1 mm and 0.1 mm can As the right choice of filters depends on many other fac- often be seen with the naked eye. Particles smaller than tors such as the quantity and composition of pollutants 100 μm ( = 0.1 mm) are only visible by means of an optical microscope. These and perhaps an assessment of the situation on site should particle sizes correspond to the filter take place. For this matter feel free to contact our team by and the operating conditions, a professional consultation using info@teka.eu. Particles which are smaller than 1...

Settling times Decisive for the settling time of particles are in particular their size and weight. Small, light particles are held in the air by air vortices. Very small particles are in a permanent state of floating and may be inhaled if they are not extracted. Inhalation may result in significant damage to the health or even cancer. The chart on the right shows the approximate settling times of particles. Source: Technical Rules for Hazardous Substances/Welding work/ TRGS 528, Issue February 2009
