- contributes to environment non-pollution
- causes increase in dispersiveness and amount of dust extracted
- simply manufactured design
- system's dimensions can be selected for specific application
- can be adjusted to available exhaust duct
- license to use the extract system is offered.

Compared with the standard counterpart, previously run at the facilities of Petrovsky metallurgical works, implementation of this extract system allowed ~ 2,8 times increase in mass of dag, ash and other solid dirt extracted.

The extract system has Ukraine's patent right № 27582.
Has been introduced into oxygen-converter plant of Petrovsky metallurgical works, Dniepropetrovsk.
~ 2,8 increase in mass of extracted dag, ash and other solid dirt.
