GOST R EN 779-2014
Filters are tested in accordance with GOST R EN 779-2014 on an automated testing system for general purpose filters AFL 114 manufactured by (Topas GmbH).
Tests allow you to control the following parameters:
- Initial pressure drop at nominal capacity, Pa.
- Initial / average dust retention capacity,%.
- The initial particle efficiency of 0.4 μm on an un dusty filter,%.
- The average particle efficiency of 0.4 μm at different dust loads upon reaching a differential of 250/350/450 Pa on the filter,%.
- Dust capacity - mass of dust retained by the filter until it reaches the final pressure drop, gr.
- Determination of the cleaning class according to GOST R EN 779-2014.
