OVERIGE PRODUKTEN other gasses and particles Filtration is vitally important The air surrounding us comprises 78% nitrogen, 21% oxygen and 1% various gases and solid particles. This last component listed comprises such elements and compounds as noble gases, carbon dioxide, fine particles, salts and gas emissions from motor traffic and industry. Although one percent sounds like very little, it does determine whether the air quality is considered healthy or unhealthy. Although the operation of a filter may appear very simple in theory, filters are in fact highly complex products. The filter...

The principles of air filtration The sieve effect The sieve effect is one most commonly applied in air filters. The principle of the sieve effect is very simple: The particle is larger than the gap between the media fibres and therefore gets trapped. There are two basic types of air filter: Filters for solids and filters for gaseous particles. Both types have the same objective, to reduce the concentration of airborne particles. Gaseous particles can be filtered out by means of adsorption. Adsorption is brought about by London dispersion forces, or Van der Waal’s forces, which act between...

European filterclassification How can one establish, as the end-user, whether a filter will provide the envisaged air quality? Throughout Europe, air filters are classified according to two standards: EN779:2012 for course and fine filters, and EN1822:2009 for HEPA and ULPA filters. Filters that are tested for compliance with these standards naturally meet stringent requirements. During such tests, the filters are exposed to circumstances which indicate precisely how they will perform in practice. As the customer, it is a comforting thought to know that all the products AFPRO Filters...

MPPS MPPS stands for most penetrating particle size. This refers to the dimensions of those particles that are the most difficult to trap. It generally lies in the region of 0.1 to 0.2 microns (μm). The MPPS has to be established before subjecting a filter to tests. The overall efficiency and the local efficiency are then determined, depending on the filter class. HEPA Filters ULPA Filters

EN779:2012 The society changes continuously. Environmental responsibility increases, work conditions are getting more important and technological developments are chasing each other rapidly. It is therefore that after 10 year the air filtrations’ most important norm is revised. Recently the European EN779 norm for course and fine dust is modified. It is expected that as from the first of January 2013 this norm will officially be accepted. To this respect we would like to inform you about the upcoming changes. Two biggest changes Introduction Minimum Test Efficiency With the new EN779:2012...

Energy labels The Eurovent energy labels are used as from the 1 st of January 2012 by all Eurovent members with their G4 till F9 filters. Convenient for you, cause this enables you to select the desired energy classification and its corresponding usage. The energy labels only relate to those filters that are in accordance with the new EN779:2012 and that are in the range G4 till F9 with a nominal debit of 3400m3/h. The energy label can be found on the quotation, the boxes, the filter frame, our The energy consumption is determined using the following equation: t = operating time (hours)...
