Research, development and testing

Do you need protective filters for specific substances?
Do you have filters that you would like to test?
Do you want to check the adsorption capacity of your filters?
Do you have protective filters with an expired warranty period and you don’t know if they can still be used?

The quality of our products is based on long-term research, development and testing of filter materials and other structural elements of filters using simulation of the real effect of a wide range of harmful substances.

Our laboratory can verify the adsorption capacity of new, prospective, filtration materials and determine the extent of protection, the resistance time and filter capacity as needed by the customer. We also test the service life of filters and determine residual capacities for subsequent use.

In addition to tests for the penetration of chemical substances, we also use mechanical and thermal stress tests in various modes to test filters;
we check the weight, pressure gradient (SIGOD) and the paraffin oil mist penetration coefficient.

We test the resistance of filters to penetration with the following gases as standard:

Formula	Gas
HCN	hydrogen cyanide
ClCN	cyanogen chloride
COCl₂	phosgene
C₆H₁₂	cyclohexane
SO₂	sulfur dioxide
NH₃	ammonia
CH₂Cl₂	dichloromethane
CHCl₃	chloroform
CCl₄	carbon tetrachloride
CH₃OH	methanol
CCl₂CHCl	trichlorethylene
(CH₃)₂CO	acetone
C₆H_₅CH₃	toluene
C₆H₆	benzene

We can also test filters against the penetration of specific gases such as chloropicrin, chlorine, nitrogen dioxide, hydrogen sulfide, sarin, mustard gas, mercury and its vapours, if requested by customers.
We use an ANSYCO gas spectrometer with digitally controlled modules to test the capacity of filters and adsorption properties of materials. The test parameters correspond to the requirements of ČSN EN 14387.
