Filtration and ventilation installation of the welding shop.

To improve the air quality and comfort of work for the welding shop workers the existing filtration and ventilation installation was modernised in November 2017. A new 75 000 cubic meters capacity installation was integrated into the existing ventilation system. Donaldson DFO-4-64 unit was used as a main dust-collecting element, to work in-line with a 80 000 m3/h radial fan.
