Absolute filterse



Basic information

• the classification of filters:

-the EPA from E10 to E12

-HEPA H13 H14 from to

-ULPA from U15 to U17

norma EN1822

HEPA (ang. High Efficiency Particulate Air filter) is a powerful air filter for air disinfection

• filters with high efficiency particulate matter wyłapujące made with sintered glass, provide air filtration through the pores of size 0,3 µm • stop most (at least 99.97%) and mechanical impurities, larger than 0.3 µm, as well: the cells of fungi, protozoa and bacteria and most viruses

• made with very thin sheets made of thin strands of glass fiber, polypropylene or borokrzemianu (formerly filters were cotton) made a harmonica and fixed in a rigid frame. Threads are pressed so that its structure reminiscent of a filter which is then laid multi-layers by creating the ultimate filter material.



• are used in boxes, boxes, boxes or spaces to work in a sterile environment (used in vacuum cleaners)

• used in many industries, for example. Microelectronics, chemistry, medicine, bioengineering, the pharmaceutical field and wherever necessary to require high air pollution • working in hospitals can remove particles even with a diameter of 0.3 microns


The efficiency of HEPA filters:

filter HEPA filter Efficiency decreases slightly with their aging, life goes back to 3-4 months, and in some cases even a year. Everything depends on the so-called. "air preparation", that is, from the use of the pre-filter. If ventilation is well executed, there are cases when HEPA filters are designed to 4 years.



Filters ULPA (ultra-low penetration air)

basic information:

• class filtration U15, U16, U17

• stop 99.999% of impurities with a diameter of 0.12 microns

• provide necessary level of control of pollutants in the environment

• lightweight and easy to install
