Marking of filtering elements of EFP-XYZ
The dynamic development of demand for filter materials in the domestic and foreign markets has demanded from the company new scientific developments. Thanks to our own innovations and cooperation with a number of foreign and domestic firms, our company has significantly expanded the product range and range of tasks in the field of industrial filtration of liquids and gases.
The expanding range of filter elements produced, new opportunities for their use, as well as the planned development prospects, required the company to switch to a new product classification system. The basis of the new classification of filter elements was based on the coding in the technical labeling of the EFP-XYZ three digits of the following features:
- X – preferential filtering mechanism or principle;
- Y – type of construction element or a type of filter material;
- Z – the chemical composition of the filter material with the exception of the number 5, which characterizes the whole class of polymer microfiltration membranes.
