ATMOSFERİK HAVA FİLTRASYONU KALİTE STANDARTLARI

EN779:2012

EN779:2012 Standard classifies air filters according to the lowest filtration efficiency. Particle size that forms a basis to the

efficiency is regarded as 0,4 μm and filters are separated into three groups. These groups are; G, M and F.

 

Mikropor is equipped with complete EN 779:2012 / ISO 16890 test system to develop new products for

market needs, improve performance of existing products and to supply filters accordance with the design

specifications.

The Flat Sheet Media Test Rig is a modular filter testing system for flat filter media and mini-filters. This enables

you to determine; Differential pressure curve, fractional efficiency, dust holding capacity.

 

 

ISO 16890

ISO 16890 Standard is a global testing standard that entered into force in the year 2018. ISO 16890 Standard, used for the

classification of air filters has replaced EN779:2012 Standard.

Since EN779:2012 could not determine how a filter performs against other particles found in the air while it tests an air filter’s

capturing capability for 0,4μm particle size only, ISO 16890, which puts air filters’ capturing capabilities into test with particles on

a broader spectrum (0,3μm-10μm), came into effect.

The ISO 16890 Standard divides air filters into four groups. The prerequisite for each group is for the filter to capture at least

50% of the appropriate particle size.

For instance, if a filter can capture more than 50% of PM1* particles, it is classified as a ISO ePM1 filter.

*Pollutants found in the air are called Particulate Matter (PM). PM is accepted as a common indicator for air pollution, and it affects humans more when

compared to other pollutants. Main components of PM are sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral salt and water. It consists of the

mixture of solid and liquid particles of organic and inorganic matters suspending in the air.

 

 

 

 

OUR COMPANY STANDARDS AND CERTIFICATES

COMPARISON OF EN779:2012 and

ISO 16890 STANDARDS

EN 1822

The EN1822 Standard involves efficient, high-efficient and ultra-low permeability air filters (EPA, HEPA, ULPA) used in ventilating

and air-conditioning, cleanroom technologies or applications in nuclear and pharmaceutical industries.

Their classification is based on the measuring of the size of particles (MPPS) passing to the clean side at a specific air speed.

 

EN1822 reports must show average and local efficiency at the stated flow rate, initial pressure drop and class of the filter.

OUR COMPANY CLEANROOMS / ENERGY EFFICIENT FILTERS

CLEANROOMS

Structures, in which the particle density can be controlled and which are built for minimizing motions (entry, growth and

concealment) of particles, germs and other unwanted particulates, are called “cleanrooms”. Inside these structures, ambient

temperature, humidity and pressure parameters can also be controlled.

ENERGY EFFICIENT FILTERS

Energy consumption, one of the basic cost items, constitutes approximately 80% of total filtration costs. Because of this

high rate, using an air filter with high energy efficiency provides cost saving and also reduces the amount of waste, since the

replacement frequency is decreased.

An invariable method is used in order to evaluate the energy efficiency of G4, M5, M6, F7, F8 and F9 class filters, and products

in which this method is implemented are indicated with Eurovent 4/11 certificate located thereon. Eurovent energy label is

valid for filter classes between G4 and F9 that are tested in accordance with EN 779:2012 Standard.

With its energy efficient filters, Mikropor protects your health and the environment while allowing you to save money.

OUR COMPANY EUROVENT CERTIFICATE

PERFORMANCE UNDER GUARANTEE

Eurovent Certification is used for air conditioning and cooling products, indicating that these products are in compliance

with European and international standards. The series of common criteria for the products is formed by rating of the

products and thus, the performances of the filters are guaranteed. By dint of detailed identification of certified products,

it becomes unnecessary to perform tests, such as extensive comparison and performance qualification tests, once again.

Thanks to the globally acknowledged Eurovent Certification, not only is the work simplified but also the trust towards

data accuracy is increased.

OUR COMPANY HIGH TECHNOLOGY

SEM, 3D & NANO

SEM/ Scanning Electron Microscopy

Scanning Electron Microscopy (SEM) is utilized in determining of surface characteristics of newly developed materials. On nano-coated surfaces, uniform and continuous filament formations, where no drop defects occur, are desired. By means of the SEM instrument, having 1.000.000x magnification, morphology of nanofibers can easily be examined. EDX is the technique utilized in order to define elemental composition on any sample or on a respective small area on a sample. EDX analysis in electron microscope is performed by exposing the sample to a scanning electron beam. Thus, elemental composition of the sample can be determined.
